Ahead of the summer heat across the United Kingdom, REHUA, the globally renowned polymer specialist, has upgraded their smart heating control, in order to be able to seamlessly transfer between heating and cooling. NEA Smart 2.0 Allowing developers and contractors to provide efficient heating and cooling from a single solution, the NEA Smart 2.0 uses a series of algorithms to regulate temperature. These algorithms allow the device to learn occupant habits and data from multiple sensors in floors and walls, creating optimal conditions for occupants. Taking the present values for indoors and outdoors temperatures and their trends, as well as the learnt data, the intelligent algorithm in the smart control automates heating and cooling so end users do not need to control it themselves. Enhanced efficiency and comfort Efficiency and comfort for the end user is improved, as the required temperature is reached smoothly Alongside this, efficiency and comfort for the end user is improved, as the required temperature is reached smoothly, without putting maximum demand on the property’s heating or cooling source, including fan coil systems and heat pumps. Particularly for contractors and developers working on sealed new build projects, ensuring moisture levels are optimal is key to preventing damp and mould that could affect occupant health. So, in order to maintain good air quality between heating and cooling, the system uses a sensor to ensure the dew point in the space is not exceeded, and can control a dehumidifier to keep moisture levels down. IAQ and moisture control Franz Huelle, Head of Technical at REHAU Building Solutions said, “We are pleased to be able to offer a complete solution for heating and cooling both residential and commercial buildings. With air quality and moisture control key concerns within the building services industry, we have developed the technology to ensure these variables are constantly controlled.” He adds, “As conditions change, the NEA Smart 2.0 system can continuously learn and update settings to ensure the desired temperature is efficiently met without causing condensation or large energy bills.” Smart control for future proof buildings Franz Helle continues, “As we explored in our guide, ‘Warming the Next Generation’, smart controls are fast becoming one of the keys to creating efficient and future proof buildings. In order to make sure specifiers, developers and contractors stay ahead of the curve with smart technology, we are committed to constantly updating our own solutions to meet demand, as we have done here.”

As our urban centers grow, so does our demand for key resources, such as energy. Currently, cities are accountable for over 60% of resource use and an estimated 70% of global carbon emissions. In the Middle East particularly, countries have experienced unprecedented population growth, increased economic activity and consequently, increases in energy consumption. Integration of sustainable systems Fortunately, industry leaders and governments are placing sustainability at the heart of regional plans for urban development. The integration of sustainable systems is no longer a value-added benefit, but rather a necessary requirement. I believe a vital element for sustainable development in our cities is energy management. Energy is a costly commodity representing an average of 25% of all operating costs in office buildings. This cost, however, can be reduced by using energy management to optimize HVAC systems employed in a building. Effective energy management Energy management involves proactive tracking, systemic management and thoughtful optimization of energy consumption in a building, with the goal of improving energy efficiency. The concept of energy efficiency takes into account a variety of factors; we must consider system design, quality of installation and maintenance, efficiency rates and personal use. If we assume a system is designed with greatest efficiency in mind, its effectiveness is still deeply impacted by installation, maintenance and use. ‘Performance drift’ issues One challenge we face with the efficiency of HVAC systems is ‘performance drift’ One challenge we face with the efficiency of HVAC systems is ‘performance drift’. When first installed, and even in the first few months, HVAC systems operate immaculately. Over time, however, component efficiency and system conditions ‘drift’ away from the originally installed operating curve, meaning that efficiency and performance of the system can degrade incrementally. The deteriorating performance of HVAC systems has consequences, such as unnecessary use of energy, resulting in higher costs and emissions, in addition to reduced comfort for building occupants. Energy efficient HVAC pumps In order to truly have an impact on energy consumption, a holistic approach must be adopted. Only by carefully examining and optimizing each part of the HVAC system, can we then find ways to improve it. In my experience with Armstrong Fluid Technology, in the last decade, the technology for HVAC pumps has been enhanced to provide up to 70% energy efficiency savings through demand-based control and parallel pumping technology. These innovations enable the pumps to operate at optimum levels, consuming as little energy as possible. Innovative smart technology Systems that incorporate innovative smart technology enable more accurate system performance analysis and optimization. Pumps can function as highly accurate flow meters that provide valuable insight for building managers and operators. Data from the intelligent connected pumps can be collected through active performance management software, which enables the HVAC system to learn, predict and optimize to deliver even greater energy efficiency and cost savings through maintained optimized performance. Systems incorporating innovative smart technology enable more accurate system performance analysis Active performance management software Active performance management software enables real time and historical data reporting that directly demonstrates system efficiency and savings. Given the global shift towards sustainable building construction, legislation on energy reporting is inevitable, therefore employing systems with this in-built capability can prove to be extremely beneficial in the future. The software can also help maintain client comfort at all times by enabling predictive maintenance. Systems can provide alerts when they detect faults, allowing for early replacement before a full breakdown. This can be particularly helpful in mission critical applications such as hospitals. Importance of analyzed data in system optimization Without the ability to analyze data, buildings managers and operators cannot properly optimize mechanical systems Evidently, collecting data is essential for many reasons, including preventing, and even reversing, the loss of energy efficiency. Without the ability to analyze data, buildings managers and operators cannot properly optimize mechanical systems, which results in unnecessary energy use, insufficient maintenance practices and any related costs. There may be hesitation in the industry to incorporate more sophisticated systems as they require initial investment, however, the returns from using more efficient mechanical systems are impressive. Executing energy upgrades for HVAC systems Simple payback on energy upgrade projects is usually reached within 3 to 5 years. Furthermore, energy savings continue for the life of the system. Properly executed energy upgrades deliver up to 40% savings on energy consumption related to HVAC operation. Savings on that level for a large facility can be impactful for business operations. Energy efficiency is not ‘visible’ but has the potential to have a transformative effect on climate change, if embraced on a large scale. If we consume energy only as we need to, then we consume less of it. This, in turn, reduces our consumption of fossil fuels and consequently our greenhouse gas emissions. Aside from short-term benefits, such as costs savings and increased operation efficiency, energy management has the ability to help conserve energy for generations to come. Embracing energy saving solutions If we embrace innovative energy saving solutions in the building services industry, then we can begin to make a difference. With the recent launch of plans for sustainable development, such as the Dubai Master Plan 2040, green infrastructure, supporting solutions, will thrive. The global shift towards embracing sustainability has made individuals and organizations call into question their impact on our planet. Embracing sustainability is no longer a preference but a strategic business approach that helps to create long-term value on a social, economic and environmental level. The role of energy efficiency, and the systems that enable it, will inevitably play a key role in creating more sustainable buildings, communities and cities.
With ongoing efforts from governments across the globe to reduce carbon emissions and with an ever greater focus on sustainability, it is vital that the HVAC sector does its part in becoming more environmentally conscious. And, while there have been steps to become more sustainable, there is a huge amount that still needs to be done to make sure that many of the targets that have been set are attainable. In buildings, both large and small, industrial heating accounts for roughly two thirds of industrial energy demand and around a fifth of global energy consumption. Figures like this show the need to have efficient and environmentally-friendly HVAC equipment in place to make the crucial steps towards reducing the contributions these systems make to our carbon footprint. High energy consumption in construction sector A 2019 report by The International Environment Agency (IEA) showed that the buildings and construction sectors combined were responsible for over 30% of global energy consumption and nearly 40% of carbon emissions. This is indicative of the steps the sector needs to take to play its role in a more eco-friendly society, some of which are already underway. However, much more needs to be done if the UK is to reach its goal of reaching net zero carbon emissions by 2050. As we envisage what a post-COVID world might look like, businesses and governments are continuing to put sustainability and lower carbon emissions at the forefront of their planning and the HVAC sector is certainly no exception. But with change in the sector a daunting prospect, decision-makers often don’t know where to start. Smart Technology use in HVAC systems Smart HVAC uses sensors that integrate with a building’s automation system With the constant growth and greater deployment of smart technologies within the HVAC sector, this is certainly a way that systems can become more efficient. Smart HVAC uses sensors that integrate with a building’s automation system. These sensors then collect information about conditions throughout the building. Heat waves are now a far more common occurrence in the United Kingdom. The Met Office estimates they are up to 30 times more likely and will be a bi-annual occurrence by 2050. It is important that any uptake in HVAC usage doesn’t lead to a drastic increase in emission generation. This is one of the areas where smart systems will become crucial. Many scientists have been unequivocal in their sentiment that heat waves are a cause of greater emissions and expect temperature records in the UK and Europe to be broken more regularly, so sites will need to be equipped to handle these conditions. Regulating temperature with hand-held devices With wireless systems now much more commonplace, temperatures can be controlled easily from hand-held devices. With these new technologies, those managing the systems can also benefit from remote monitoring and maintenance, reducing the need to travel to the site for yet another environmental incentive. To accompany the smart systems, equipment including smart thermostats can be installed to maximize HVAC efficiency. Other smart systems available to businesses include smart furnaces and air conditioning units that are far easier to operate than their traditional counterparts. Reducing unnecessary ventilation While global temperatures continue to rise, air conditioning usage has increased and has contributed to greater levels of energy usage. A huge amount of needless emissions are generated by unnecessary ventilation, contributing heavily to heat loss and overall energy wastage. Recirculation of air is a traditionally lower energy cost method of retaining heat and keeping emissions low, however, we must be mindful of the risks associated with recirculating air. The risk of circulating diseases is negated somewhat with heat recovery ventilation, which both removes the risk of disease spreading and improves energy consumption. Efficiency performance of new AC units Air conditioning units in particular contribute significantly to a building’s energy consumption Air conditioning units in particular contribute significantly to a building’s energy consumption, equating to 10% of the UK’s electricity consumption and as such it is important that we bear in mind ways to counteract the emissions this creates. Global energy demand for air conditioning units is expected to triple by 2050, as temperatures continue to rise year on year. The efficiency performance of new air conditioning units will be the key, when it comes to ensuring that escalating demand does not equate to greater emissions. Another issue for suppliers and manufacturers to address is differing rates of consumption for AC units in different countries, with units sold in Japan and the EU typically more efficient than those found in China and the US. Modularization Modular HVACs have also become increasingly popular in recent years. Modular HVACs are responsible for heating, cooling and distributing air through an entire building, with their increase in popularity largely down to their greater levels of energy efficiency, cost effectiveness, flexibility and substantial ease of installation and maintenance. Modular HVACs can be tailored specifically for workspaces and they often allow work to be done on the systems without disturbing the workforce, achieved primarily through rooftop placement. Commercial workspaces are larger and often require differing needs to residential properties and can cater to a wide range of the specific requirements of work and commercial spaces. As we strive for lower carbon emissions, it seems that this trend will continue and will become a key area in reducing emissions that HVACs have traditionally generated. System maintenance and training To meet government and industry requirements, many new buildings will require HVAC systems that can be maintained simply in order to perform in a more energy efficient way. Many companies are looking at ways to become climate neutral and significantly reduce their footprint Many companies are looking at ways to become climate neutral and significantly reduce their footprint. Companies are following the likes of German-based company, Wilo Group, who have announced they are committing to sustainable manufacturing by developing a new carbon neutral plant and HQ in the next few years. Lowering carbon footprint As we continue to move towards an ever more environmentally conscious society, it will be of paramount importance for companies, governments and the public to think about ways in which we can lower carbon emissions. Smart technologies will certainly be at the forefront of this, negating many needless journeys and making it easier for industries to adjust settings and tackle issues remotely. Greater levels of training will help equip us with the tools to make sure we are best placed to reduce emissions and be more sustainable as a result. While the steps outlined above do show some progress and measures we can take, there is far more that we can do as a sector to significantly reduce HVAC’s carbon footprint and once we have moved beyond the impact of the COVID-19 pandemic, this will surely be at the front of industry leader minds.
The education field was faced with multiple challenges this past year. Not only did the COVID-19 pandemic bring the necessity of online learning, but it has also brought up necessary changes to physical schools and universities, when reopening time arrives. The health and safety of students, staff, and faculty has become a priority for directors of school operations, who have been working to properly adapt school facilities to this new reality we are facing. Ensuring health and safety of students Besides safety measures like the addition of hand sanitizers, reinforcing the use of masks and social distancing, these professionals were faced with an even bigger and more important issue: ventilation and airflow indoors. School facilities have many unique features that increase the concerns regarding indoor air quality. Occupants are usually very close together, considering that school buildings have four times as many occupants as office buildings for the same amount of floor space (EPA). Variety of pollutant sources According to the WHO, the virus can also spread in poorly ventilated and/or crowded indoor settings Other issues include tight budgets, the presence of a variety of pollutant sources (including specialty classrooms, like art, gyms, and labs), concentrated diesel exhaust exposure due to school buses in the property, and a large amount of heating and ventilation systems that may cause an added strain on maintenance staff. On top of that, schools usually have to worry about child safety issues, concerned parents, and wellbeing of faculty and staff. According to the World Health Organization (WHO), the virus can also spread in poorly ventilated and/or crowded indoor settings, where people tend to spend longer periods of time and aerosols particles tend to be suspended in the air, which leads to the importance of indoor air quality in classrooms. Importance of natural ventilation and HVAC systems Natural ventilation and HVAC systems are the basic methods to bring clean air indoors, however, schools that rely only on these methods of ventilation need to be aware of their potential limitations. HVAC systems, for example, should have regular maintenance checks and filter changes, in cases where the system is less sophisticated, schools need to add new forms of air purification to effectively mitigate airborne pathogens. Studies showing quality of air in US schools Studies have shown that low-standards HVAC ventilation systems may contribute to airborne diseases transmission due to low air exchanges rates, poor maintenance and lack of high-efficiency filters. For this reason, portable air cleaners are becoming more and more popular to create a healthy learning environment. EnviroKlenz, an indoor air quality company, conducted real-life setting studies to show the quality of the air in schools in different areas of the United States. The study measured the amount of particulate matter in classrooms, with and without the use of additional portable filtration systems, which allowed for comparison and analysis of the benefits a portable air cleaner can provide. National EPA standards for indoor particulate matter The study also compared the current data to the national EPA standards for indoor particulate matter (PM), in order to evaluate the performance of the EnviroKlenz Air System Plus. The IAQ meters focused on PM1, which is about 1 micrometer in size (70 times smaller than the diameter of human hair!). The systems ran in operational educational environments, with daily schedules being carried out as usual and results can be seen below. School directors of operations also must pay attention to the different technologies available in portable air cleaners. With the growth of the industry, new emerging technologies have come up, and there’s still lack of third-party testing to prove their efficacy. Other technologies, like carbon filters, do not work against airborne pathogens and may release harmful byproducts back into the environment. EnviroKlenz Air System Plus EnviroKlenz Air System Plus, which utilizes a patented earth mineral technology to capture pathogens, is at 99.9% efficiency The EnviroKlenz Air System Plus, which utilizes a patented earth mineral technology to capture virus, bacteria and other harmful pathogens, is at 99.9% efficiency and is complemented by a medical-grade HEPA filter and UV-C lights, was also tested against a carbon-based air cleaner in a classroom. As shown below, the carbon system struggled to keep consistency, with peaks and valleys throughout the day. Meanwhile, when the EnviroKlenz Air System Plus was turned on, the PM1 levels were steadily low for over 4 consecutive days. Deploying portable air cleaners in classrooms Adding a portable air cleaner to classrooms and common areas will increase air exchange rate and mitigation efforts, but the long-term benefits go beyond the pandemic. Studies have shown that good indoor air and ventilation rates are directly linked with students’ academic achievements and can increase performance. High CO2 levels in a school environment are also associated with lower average annual attendance and worse individual test performance. Other long-term benefits include reducing symptoms of those who suffer from respiratory diseases and creating a favorable environment not only for students, but also for teachers and staff; while bringing a sense of comfort and well-being to parents and the community. Combined benefits of air filtration, ventilation, and purification “When we’re operating more normally, maybe we’ll be able to cut down on some of the traditional flu-peaks that schools have, or cold peaks, that kids just bring into school, by managing the airborne virus and bacteria quality,” said Peter Twadell, Head of School at Birches School in the US, and an EnviroKlenz Customer. School officials need to consider the combined benefits offered by filtration, ventilation, and purification methods to create the healthiest environment possible. Thinking in a pandemic-conscious mindset, air quality has gained the recognition it deserves in creating a proper and healthy learning environment.
It’s shaping up to be a long, hot summer for HVAC contractors and their customers. Disruptions in the nationwide supply chain that began during the COVID-19 pandemic still have not been resolved. Shutdowns last summer played havoc with the supply of parts, and suppliers are still playing catch up, as raw materials remain scarce. Furthermore, prices are going up among some components and key raw materials. Waiting times for parts can run into weeks or even months. Supply shortages of HVAC equipment Summer weather increases the demand for HVAC equipment, especially in hotter climates. A spike in air conditioner demand is generally welcomed by most contractors, but supply shortages make it difficult to deliver on customer needs. Managing a backlog of impatient customers is a new challenge for many HVAC companies. The shortages impact materials, such as steel, aluminum, copper and plastics, whose costs are expected to rise in coming months. Among metals, the price hikes could be 20 to 30%, while prices of plastics could almost triple. Copper futures recently reached an all-time high, and steel price indexes are also at record levels. Shortages of electrical components Shortages have been reported of copper and electrical components, such as motors and compressors Shortages have been reported of copper and electrical components, such as motors and compressors, which are specific to the units that use them. There is also a shortage of microchips that are components in high-efficiency systems and furnaces, and resins used in the evaporator coil pans are scarce. Some HVAC supply firms have had difficulty obtaining evaporator coils used in air conditioners. Specialty items such as control boards have a wait time of up to two to three weeks, or longer. Shortages projected till end of 2021 The shortages are projected to continue until the end of 2021. Even as small shipments trickle in, they are often sold quickly. The situation is unfamiliar to the HVAC trade, which has traditionally not had issues with equipment availability. Shortages in the HVAC market are a reflection of broader supply and cost challenges of the construction market. Prices for goods used in residential construction have increased almost 10% over the past 12 months, according to the U.S. Bureau of Labor Statistics. Higher transportation costs impact supply chain Higher transportation costs are impacting both the supply chain and HVAC contractors. Personnel shortages continue to plague many HVAC companies, too, and a technician shortage is also contributing to longer wait times in some areas. A scarcity of labor has been a 20-year challenge for the HVAC industry, but it is reaching new levels as days go by. Order in advance and stockpiling equipment Alternatively, HVAC contractors may seek to switch brands to help ease availability issues One approach contractors are taking to the problem is to order equipment in advance and stockpile it for when they need it. One Denver contractor reportedly ordered almost a million dollars of equipment in advance. Alternatively, HVAC contractors may seek to switch brands to help ease availability issues. Identifying a manufacturer that has stock available can ease the inconvenience of customers having to wait for new equipment. need for regular HVAC maintenance Another approach is to educate homeowners about the importance of maintenance, such as changing filters, which can avoid a need for larger repairs involving equipment that is in short supply. Maintenance service is doable because it doesn’t require new equipment, replacements or add-ons that can be hard to come by. Unfortunately, among consumers, maintenance may have been delayed or ignored during the pandemic, which is aggravating the urgency of the current situation.
Artificial Intelligence (AI) is an emerging tool for a long list of applications, including the ability to analyze and ensure optimum performance of an HVAC system. Emerson’s Sensi Predict smart HVAC solution is an example of how AI can boost the capabilities of HVAC. It has been recognized with a Silver Edison Award in the Innovative Services – AI category. Sensi Predict smart HVAC solution Sensi Predict combines inputs from 10 sensors in an HVAC system and analyzes the performance of heating and cooling systems in real time. Intelligent monitoring alerts home owners and their contractors, when HVAC systems are not operating at full efficiency. The alerts, which can be accessed on a smartphone, can predict and prevent problems, ensure corrective maintenance, lower utility costs, and prolong the life of an HVAC system. Fault detection and diagnostics are a new frontier in HVAC technology, delivering a seamless and simple user experience. Sensi Predict HVAC system configuration Here is how the Sensi Predict system is configured: Sensors monitor the temperature of the air flowing from the HVAC system into the home, and also the return air temperature, coming from the home back into the system. Sensors also monitor temperatures in the liquid and vapor lines in the refrigerant loop, and the indoor and outdoor control lines, communicating back and forth from the thermostat to the outdoor unit. Other sensors monitor the current draw and indoor voltage of indoor units, and current and voltage to the outdoor units. Data from the sensors is used to analyze how well the HVAC is operating, including detailed monthly performance checks, with results issued to the home owner and the contractor. If a warning is detected, an alert will be sent in real time. 24/7 monitoring The 24/7 monitoring is summarized in a personalized home owner portal and monthly performance reports The 24/7 monitoring is summarized in a personalized home owner portal and monthly performance reports that include any alerts, loss of performance, runtime and estimated cost and filter status. Actionable alerts tell when a problem is detected, sent via an email with a straightforward explanation and recommended action. “Our heating and cooling systems are critical to the health and comfort of our families and the environment, yet we have little visibility into how they perform on a day-to-day basis,” said Jamie Froedge, Executive President of Emerson’s Commercial and Residential Solutions business. The Sensi Predict systems seek to provide additional visibility. Sharing real-time system insights The Edison Awards highlight top-tier new product innovation, service development and human-centered design. Named after inventor, Thomas Alva Edison, the awards recognize and honor global innovation. The award to Emerson’s Sensi Predict system recognizes it as a 21st-century solution to the maintenance of home heating, ventilation and air conditioning systems, sharing real-time system insights, in order to help home owners monitor performance and prevent unexpected problems. Maximize system lifetime and minimize energy costs “We are honored to be recognized for this innovative technology that provides both awareness and peace of mind, when it comes to an essential component of the home,” said Jamie Froedge. Sensi Predict also provides benefits related to installation, by validating a quality install and eliminating call backs. Over time, it maximizes system lifetime and minimizes energy costs. service and maintenance information In terms of maintenance, the system provides information to ensure that all contractor truck rolls generate revenue and decrease the average time on site.

Home owners can access the Sensi Predict Homeowner Portal on the official website for detailed information, based on real-time data about how their system is functioning and its performance history, energy usages and costs and predicted maintenance needs.
What do customers want from their HVAC company? It’s a challenging question, and the answers reveal a path to a more successful and customer-centric company. There are numerous articles written that offer consumers advice on choosing an HVAC company. In the simplest terms, wouldn’t it be possible to ‘reverse engineer’ that advice to provide a roadmap to guide HVAC companies in how to succeed? Addressing consumer concerns Often, consumers’ concerns surround whether a company is a reputable and/or a well-managed business. Answering questions about basic requirements, such as insurance should be easy. Another element of consumer-oriented advice on choosing an HVAC company is to find one that is qualified to do the job. For example, able to work on the specific type of equipment a consumer has, whether central air conditioning, humidifiers, heating sources, or whatever. From the perspective of the HVAC contractor, this advice points to a need for constant training and updating of skills related to various equipment types. Seeking HVAC specialists Customers may be looking for specialty service, specific to a certain type of equipment or type of installation Consumers are also advised to seek out specialists in the work they need doing, whether a repair, a new installation or related to a specific type of equipment. Contractors must both understand their own strengths and weaknesses and be able to communicate them clearly to put customers at ease. Consumers will also be looking for contractors, who are experienced in repairing the brand or type of system they have. Customers may be looking for specialty service, specific to a certain type of equipment or type of installation. Contractors should constantly evaluate their skills-sets, their strengths and weaknesses, and provide full transparency to enable customers to make the most informed decisions. Better to walk away from a job than to overextend or misrepresent a contractor’s skillset. Such overreach never ends well and can damage a contractor’s broader reputation. HVAC contractors come in all sizes Customers will also be looking to evaluate the size and stability of the HVAC company that they work with. HVAC contractors come in all sizes, of course, and the size of a company does not necessarily reflect on the quality of work. However, stability and a good reputation are essential, especially for a smaller company or one-man shop. Consumers are often advised to ask for references, especially if dealing with a smaller contractor. HVAC businesses can be proactive in this regard by keeping references handy and even collecting customer testimonials to share with prospective customers. Positive reviews a key indicator Online reviews, hopefully all positive, are another element that can help to put prospective customers’ minds at ease. Ideally, if an HVAC contractor is doing a good job, positive reviews, testimonials and references will happen organically. Consumers are often advised to ask for certifications to document an installer’s skillset, so keeping up with the related paperwork will ensure that a customer is comfortable with any contractor’s skill level. Specific HVAC contractor license requirements Specific contractor license requirements vary by state and even at the local level Specific contractor license requirements vary by state and even at the local level. Required license numbers should be displayed on websites and promotional materials, and most states have an online directory listing of licensed contractors. Be attentive to other requirements, too, such as the special EPA certifications required to use refrigerant. Consumers expect their HVAC contractors to guide their buying decision, whether determining the correct size HVAC unit to serve a specific home size, analyzing flow rates, or recommending systems to meet specific needs. Striking a balance between simplicity and technical detail Delivering on these expectations requires a delicate balance between simplicity and technical detail. The customer needs to be comfortable that the installer knows his stuff but does not want to be overwhelmed by arcane technical discussions or puzzling acronyms. Best by far is to keep it simple (and be willing to provide additional detail – described in layman’s terms – if the customer has questions). Membership in local trade associations can provide additional credibility to a contractor, and provide additional sales and networking opportunities, too. Importance of warranties Warranties are another critical issue for consumers. Everyone offers manufacturers’ warranties, but there is an opportunity for HVAC contractors to offer even more, whether an extended warranty, inclusion of labor, as well as parts, work guarantee on repairs, and/or an extended maintenance contract. Availability 24/7 could enable a contractor to take work away from a competitor Customers should be warned that maintenance or repairs performed by an unqualified company may void the manufacturer warranty. Availability in an emergency or on short notice is another way HVAC companies can differentiate themselves among consumers. Availability 24/7 could enable a contractor to take work away from a competitor who is closed for the weekend. Emphasizing on customer services Customer service also requires a personal touch, so an ability to communicate well with potential customers can generate extra business. Emphasize listening skills and make sure customers know they are being heard. In all dealings with customers, be straightforward and honest in order to build long-term trust. To grow a successful HVAC business, prepare proactively to answer the questions customers are most likely to ask.

A large manufacturer of steel cables from Detroit, Michigan contacted Wattco with a problem that the cables they manufactured were corroding in their warehouse and needed a solution to prevent this from happening. Steel products that often sat in inventory for long periods of time were more prone to corrosion. Traditionally, light lubricating oil was used to coat the cables, preventing rust from settling in. The cables were exposed to a steam heating tank, containing light oil at ninety-five degrees Fahrenheit. The problem was that the oil had a lower than average viscosity and tended to disappear after a period of time. Oil immersion heaters Oil that has a higher viscosity can solve this problem. It would coat the cables and offer a longer storage life than before Oil that has a higher viscosity can solve this problem. It would coat the cables and offer a longer storage life than before. The trick was to heat it up to 220F, and make the oil more viscous without sacrificing the quality of the cables. Wattco provided 12 immersion heaters, each with 9KW 480V 3PH that had control panels and a redundancy system that prevented downtime. Thermocouples for heater safety Two thermocouples were used – one for temperature control and the other for high limit shutoff to safeguard the heaters. The heaters were also overrated to provide the customer additional power available. 120,000 LBS of cable was able to be treated with oil reaching 210 degrees temperature. Wattco suggested a high limit setting of 275 degrees to avoid overheating. This was easily programmed in the digital temperature controllers. Once we installed the new system, the process was monitored for 6 months and found no additional signs of corrosion. Benefits include: No maintenance costs on process heaters Safety temperature controller that prevents overheating Cables are fully protected from corrosion Electric industrial heaters are fairly inexpensive and last for years

Underfloor air conditioning systems and HVAC systems pioneer, AET Flexible Space, has announced that the company won the title of ‘Retrofit Project of the Year’, at the H&V News Awards 2020, for its work supplying its HVAC system for the refurbishment of the 24 St James Square building, in London, United Kingdom. Underfloor AC system installation The judges commented that the project was ‘an innovative use of building services, which addressed the challenge of a historic site with low ceiling height and extensive period features’. They also particularly highlighted the benefits of the flexibility of AET’s underfloor air conditioning technology. They highlighted the benefits of the flexibility of AET’s underfloor air conditioning technology One of the key challenges presented by the refurbishment of the Grade 2 listed 24 St James Square property was the need to simultaneously preserve key architectural features of the building, while at the same time, also providing flexible, modern, and premium office space that would suit the requirements of incoming tenants. Flexible air conditioning at each floor plate The re-modeling of the office interiors at all levels of 24 St James Square building was driven by seeking to maximise floor space and take full advantage of views from the double aspect interior, as well as providing flexible air conditioning at each floor plate. This would simply not have been possible with a conventional ceiling-based air conditioning system. M&E Consultant for the 24 St James’s Square project, Vic Holloway, from Edward Pearce LLP commented, “At the outset of the design process, it was clear that the refurbishment delivered significant challenges in delivering fully serviced accommodation, while maintaining respectable floor to ceiling heights.” AET downflow units installed Vic Holloway adds, “The AET downflow units promptly stood out as the obvious candidate for several reasons, including having the absolute minimum requirement for floor void height, and offering excellent distribution of cooling, heating and ventilation evenly across the whole floor, whilst reducing energy consumption.” Underfloor air conditioning CAM-V system AET Flexible Space’s underfloor air conditioning CAM-V system was perfectly suited to this complex project AET Flexible Space’s underfloor air conditioning CAM-V system was perfectly suited to this complex project, because it makes use of the space beneath a raised access floor, in order to create the air ventilation path, eliminating the need for ceiling-based services and associated duct and pipework, and thereby maximizing floor to ceiling heights. The high floor-to-ceiling heights and preservation of the windows and original ceilings also created a brighter and more airy office environment. Converting residential buildings into Class A office space Refurbishment of existing buildings has been identified as a key way to increase the sustainability of the construction industry, especially in densely built-up cities like London. However, converting residential buildings into Class A office environments is often a major challenge. AET’s underfloor systems are perfectly adapted to this challenge, as they require minimal adjustments for installation, and provide all the necessary heating and cooling for a commercial building. The 24 St James project has already won the ‘Best Office Architecture London’ award at the 2019 International Property Awards, and space is currently being let as Grade A listed office space, by BNP Paribas Real Estate.
Electricity produced through solar panels is used for heating water effectively and efficiently when attached to immersion water heaters equipped with sensors and controls. Depending on the average hours of daylight and the number of panels contained in the system, not all of the electricity produced is utilized in the home or business. Some of the electricity produced can be stored for later use. Or, sold back to the electric company for cash or credits. Unused electricity When businesses are “hooked to the grid” they can sell unused electricity to the power company, depending on state and local regulations. “Hooked to the grid” simply means the home or business's electric power remains tied into the municipal or private power company. So excess electricity can be sold. Or, if not enough electricity is generated by the solar power system the homeowner has immediate access to electricity. Using solar heaters Most electric companies pay far less than what they would sell everyone the same electricity for. So it’s better to store and use, than export to the grid. Circulation water heaters (or “inline water heaters”) particularly those used in a solar power system have far more uses than they are currently being used for in the home. Many homeowners would find it far too expensive to use these water heating elements for their pool Many homeowners would find it far too expensive to use these water heating elements for their pool while buying electricity from a power company. But when produced by the sun, it is more cost-effective. Certainly, pools and steam rooms are extravagant uses for solar-powered water heaters. For those already using these luxuries, heating the water more efficiently keeps more money in their wallets for other necessities. Heat radiation Many places are utilizing warm floors to heat their homes. Since heat rises, the floor is a good place to start with any heating system. Pipes laid in the floors, hooked to an electric water heater with concrete poured over them, make excellent radiant heating. Particularly when those floors are tiled. Solar Power System It is surprising how many large corporations continue to spend large amounts of money on electricity without considering solar power system solutions. A circulation system can be used to heat a building inexpensively using solar panels tied into the grid as insurance for electricity during extended periods of darkness. Keep in mind that even cloudy days produce some solar power. Using an immersion water heater to heat a plant or office building is cost-effective, even though the initial cash outlay may be expensive to build that solar power system. Cost-effective Tying solar power systems into the local electric system is not only wise. It can also be financially beneficial depending on the amount of electricity generated versus the amount of electricity used. Utilizing a backup plan is always the preferred method. Therefore, it is best to hook into a battery storage system for one’s solar power system. As stated previously, it’s more profitable to use one’s own electricity produced than to sell it to the power company, but the latter is a viable alternative when excess electricity is produced. Grid Connection is Essential Maintaining a connection to the grid makes sense in a variety of ways. It provides an outlet for the sale of the excess electricity produced and a reliable backup during extended periods of low production. There is always a possibility of overproducing and selling electricity back to the power company Sure, there is always a possibility of overproducing and selling electricity back to the power company. That’s more of a bonus; however, it is much more beneficial to be able to flip the switch and use your grid connection to warm your home or power your business. Actually, in most cases the change over from grid to solar or battery backup is seamless. Utilizing Storage Tanks Another backup source for heated water is storage tanks. Using an immersion heater for water tanks will ensure that after the water is heated, either by solar or the regular power source it can be stored in insulated storage tanks for later use. Temperature control panels can be placed within the tanks that control the water heater to ensure consistent heat. Many homes now use solar to circulate and heat their water by the sun’s warmth. These only use their immersion circulation heaters for backup. Valuable alternative These are particularly beneficial to municipalities that maintain purified water for residents’ use. Although hot water is not normally provided to the residents, freeze protection is provided through water temperature controls. These can also be linked to solar power systems with immersion water heaters that could be placed on, in, or around the storage tanks. In summary, immersion water heaters coupled with a solar power system are a valuable alternative to high-cost electricity and heat or hot water production in the home or business.
