As the UK continues to battle through the coronavirus crisis, HVAC business owners and installers can be putting some of their enforced downtime to good use. This period of subdued trading is a rare opportunity to get into better shape for when economic activity picks up. One way of doing this is by sharpening the focus on markets which promise strong growth – and few markets are growing faster than that for heat pumps. The potential here is huge. Some 28,000 heat pumps are currently installed in the UK every year, and before the pandemic this number was rising annually at a rate of 15-30%. That equates to sales doubling every three to five years. New-builds account for the majority of those sales, but 30% are retrofits, and about 30% of those retrofits are in private residences. This means there’s a big opportunity for doing conversions from oil boilers to heat pumps at rural homes not connected to the gas grid. The ‘New Normal’ and Heat Pumps It is only realistic, of course, to expect a lingering dip in HVAC sales of all kinds, including heat pumps, until the post-pandemic world gets back on its feet. But when we do turn the corner into the ‘new normal’, heat pump sales will again climb strongly. One reason for this is consumer demand, the other is government policy. End-users are now increasingly aware of the dangers and disruptions threatened by carbon emissions and climate change – informally known as ‘the Blue Planet Effect’ – and more are being guided by their consciences to make environmentally-responsible heating choices. An Expected Spike In Demand Many end-users are also encouraged by the prospect of receiving payments from the government through the Domestic RHI tariff. When we do turn the corner into the ‘new normal’, heat pump sales will climb strongly If RHI tariffs are the carrot, however, the government is also going to wield a big stick. The Chancellor’s spring statement last year dropped the bombshell that low-carbon heating systems, not fossil-fuel heating, should be installed in all new homes built after 2025. Though this policy might perhaps get slightly delayed and diluted, there can be no doubting that radical change is on the way. With all this in the pipeline, the industry should be preparing now to cope with the increased demand. But there’s some way to go: of the UK’s 120,000 registered gas engineers, merely 600 or so are MCS-registered to install heat pumps. Many more will be needed. MCS Certification Some installers are already recognizing this opportunity. Some 28,000 heat pumps are currently installed in the UK every year, and before the pandemic this number was rising annually at a rate of 15-30% This is evident in the heightened level of interest in the one-day introductory heat pump courses run nationwide by the Viessmann Academy. These courses provide a useful overview of what heat pump installations involve, helping participants decide whether or not they would like to go on to qualify with the MCS quality assurance scheme. This is a crucial decision, because having MCS certification is an obligation when installing equipment eligible for Domestic RHI payments. Some course participants decide to take the next step to MCS certification straight away, others decide to wait a while – but standing still in a fast-moving market can mean getting left behind! F-Gas Certification So what else must HVAC businesses and installers consider about heat pumps, in order to stay ahead of the game? In addition to MCS certification, F-Gas certification is also necessary when split air source heat pumps are installed. This is because the outdoor and indoor units have to be connected on-site with refrigerant pipework. Some installers choose to get F-Gas certified themselves, others sub-contract this part of the job to someone who’s suitably qualified. Of the UK’s 120,000 registered gas engineers, merely 600 or so are MCS-registered to install heat pumps It is possible to sidestep this need, however, when it is appropriate to install a monobloc heat pump – and the widening choice and affordability of monobloc designs is making them appropriate for a wider range of properties. A good example of this is Viessmann’s new Vitocal 100-A, an outdoors unit which has no need for a complementary indoor unit and is also easy to install because most components are integrated in the unit. New, compact and affordable air source heat pumps such as this, offering much-needed space-saving solutions for urban homes, are another reason why the heat pump market will boom. The Challenges Of Heat Pump Installation Though technological advances are making things easier, installing a heat pump isn’t ever going to be quite as straightforward as replacing an old boiler with a new one. Before starting an installation, first it is necessary to assess whether a heat pump is suitable for the property. This means checking that the property is well-enough insulated; checking the existing system’s radiators, which may need supplementing or replacing with bigger radiators or underfloor heating because of the lower flow temperatures of a heat pump system; and calculating the required size of the heat pump according to the building’s heat loss (and not including hot water demand). This period of subdued trading is a rare opportunity to get into better shape for when economic activity picks up At the installation stage itself, much of the work will be familiar to boiler installers, though weather compensating controls are obligatory for all MCS-approved work and as part of building regulations Part L. It’s also important to note that planning permission requires minimum distances between the heat pump’s outdoor unit, the plot’s borders, and neighboring properties. If this seems complicated, it doesn’t have to be: some heat pump manufacturers provide a calculator to simplify the task. Now Is The Time To Be Proactive Just as installers need a little time to assess whether a property should switch from a boiler to a heat pump, end-users also need a little thinking time, to consider adopting a technology new to them. By being proactive, HVAC businesses and installers can reap what they sow When customers get in touch because their existing boiler has broken down, the pressure for a quick fix can rule this out. But right now, when many of us have time on our hands, there’s the chance to inform customers of alternative heating solutions before their boiler needs replacing. Taking such pre-emptive action, by emailing information or mailing leaflets to customers, does require a little effort, but at least now there’s the time to do it. We are heading into a new era which will see boiler sales decline while heat pump sales rise. By making preparations for these profound changes, and by being proactive, HVAC businesses and installers can reap what they sow.
Strategic electrification encompasses a host of solutions aimed at decarbonizing Earth’s atmosphere, decreasing pollution and reducing the costs of modern comfort and technology. Also known as “beneficial electrification”, this movement requires increased energy efficiency and end uses powered with electricity from cleaner grids and renewable sources. The movement will transform both the built environment and society’s modes of transportation. Despite the complexity of its challenges, strategic electrification can no longer be dismissed as a niche or a possibility of the far future. The movement is happening now, driven by a mix of public and private entities on various levels proceeding along voluntary and mandatory paths. What Is Being Done? In the absence of formal federal action on climate change — including the Clean Power Plan and Paris Accord — cities, states, municipalities and utilities are continuing to develop their own decarbonization strategies. There are now nearly 450 cities in the U.S. that have committed to 80% carbon reductions by 2050 The goal is to achieve this through a variety of policy mandates such as taxes, building codes and portfolio standards. This is in addition to voluntary approaches that can include utility rebates and construction decisions such as choosing a passive house design; updated building efficiency targets; system-specific electric mandates; and comprehensive gas bans. Just recently, Santa Cruz became the 30th city or county in California to enact a measure limiting or prohibiting the use of natural gas in new construction, according to an article published by Yale Environment 360. The Carbon Neutral Cities Alliance Many organizations have rallied around these strategies. For instance, the Carbon Neutral Cities Alliance (CNCA) is one of the many organizations that have rallied around the strategies that must be employed to reach carbon neutrality. CNCA is a collaboration of leading global cities working to cut greenhouse gas emissions by 80-100% by 2050 or sooner. They’ve adopted some of the most aggressive GHG reduction targets undertaken anywhere by any city. Mitsubishi Electric Trane HVAC US was one of the organization’s first HVAC participants, providing expertise and product knowledge to support their continued efforts. Major CNCA cities include New York City, NY, San Francisco, CA and Washington, DC. If We Don’t Electrify, How Could That Impact the Environment? Cities are working aggressively to reduce fossil fuel use because our CO2 levels are trending in a dangerous direction. As a naturally-occurring greenhouse gas (GHG), CO2 helps earth retain enough warmth to sustain life but too much can lead to excessive warming. If our global energy demand grows and we continue to use fossil fuels in the same way, the average amount of atmospheric CO2 will likely exceed 900 ppm by the year 2100 For 800,000 years, before the Industrial Revolution and the widespread adoption of fossil fuel-burning technologies, the highest global average atmospheric amount of CO2 was 300 parts per million (ppm), according to the National Oceanic and Atmospheric Administration (NOAA). 407 ppm is the current average amount, per a trend report published by the Global Carbon Project. The NOAA also reports that if our global energy demand grows and we continue to use fossil fuels in the same way, the average amount of atmospheric CO2 will likely exceed 900 ppm by the year 2100. As atmospheric CO2 increases, the global temperature also increases, potentially reaching 1.5° C above pre-industrial levels between 2030 and 2052. At this temperature, the majority of climate scientists expect environmental changes to include rising sea levels, increased flooding, droughts, extreme heat, wildfires and new risks to human lives, infrastructure and biodiversity. According to the U.S. Energy Information Administration, buildings (residential and commercial) account for nearly 40% of the nation’s total energy demand — and about 75% of all electricity use. Where Does The HVAC Industry Fit In? Worldwide, all-electric heat pumps are the most popular technology for decarbonizing heating and cooling. VRF heat pumps and heat-recovery systems contribute to lower carbon footprints and benefit strategic electrification by reducing overall costs for commercial building owners, consumers and society. Instead of burning fossil fuels, a VRF heat pump provides heating to zones by introducing ambien heat its outdoor unit extracts from the air or a nearby water source. During cooling, VRF heat pumps reverse this process as indoor units transfer heat from zones to the outdoor unit which then rejects the heat. Until recently, some specifiers in northern regions felt obligated to select a gas-powered furnace or electric resistance for heating systems due to air-source heat pump derating at sub-freezing temperatures. Today that’s not the case. Mitsubishi Electric Trane HVAC US' SUZ universal outdoor unit uses Hyper-Heating INVERTER technology Air-source VRF systems now use advances such as flash-injection technology in the compressor to offer unprecedented levels of capacity and efficiency at low outdoor ambient temperatures. This creates opportunities to replace fossil-fuel-burning equipment in more regions than before. VRF heat pumps and heat-recovery systems help building owners, architects and engineers solve challenges associated with decarbonizing the electric grid as well as emerging building codes, standards and legislation related to decarbonization. Federal standards and programs like ENERGY STAR®, tax credits and utility rebates will continue accelerating adoption of energy-efficient alternates to fossil fuel burning systems. The Decarbonization Challenge The decarbonization challenge is significant and complex, but change is happening now. At Mitsubishi Electric Trane HVAC US, we’re passionate because we recognize the dangers of climate change and acknowledge the significant role we can play in decarbonization efforts. The decarbonization challenge is significant and complex, but change is happening now Legislation, codes, financial incentives, product innovations and environmental advocacy encourage the transition from fossil-fuel-burning equipment and will continue to evolve. We’re doing our part by researching, developing, manufacturing and providing training for the all-electric heat pumps and VRF systems that enable society to enjoy improved comfort while reducing both costs and carbon emissions. Ultimately, strategic electrification can only be successful if it’s associated with personal comfort and prosperous communities.
Thermo King®, a provider in transport temperature control solutions and a brand of Trane Technologies, announced that its new hybrid refrigeration systems for trucks and high-loaders are being delivered to customers across Europe. The new T-Series Hybrid and UT Hybrid refrigeration systems seamlessly switch between diesel and electric mode allowing transporters to operate in inner cities, residential areas and low emission zones with the unit’s diesel engine turned off. Greggs, UK’s bakery food-on-the-go retailer with over 1,800 shops nationwide and serving over six million customers a week, is one of the first customers in Europe to experience the benefits of the new hybrid refrigeration systems. Three new trucks with Thermo King’s hybrid systems will contribute to lowering the environmental impact and reducing operating costs of their truck transport operations in central London. Reducing sound level and eliminating emissions “Thermo King units have been our systems of choice for several years now. Their units have delivered good flexibility and work efficiency to our operations, and we could also always count on the Thermo King dealer service network to support us,” said Richard Penna, group logistics manager at Greggs. “We’re very cautious about the sustainability of our transport operations. It is paramount for us to operate in inner cities with as little noise and reduced emissions as possible. It was a natural choice to work with Thermo King and equip our trucks with these new units that can easily switch from diesel operation to electric, reduce the sound level and eliminate emissions. On top of that, we expect to benefit from the lower daily fuel consumption.” Trailer hybrid refrigeration “Thermo King Hybrid technology was designed to help transport and delivery companies future-proof their refrigerated operations and investments. With this solution they can stay ahead of regulations, control their total cost of ownership and achieve important sustainability goals,” said Colm O’Grady, product manager at Thermo King. “Thermo King was the first to offer its European customers a trailer hybrid refrigeration. Now, our truck transport customers can also benefit from this cleaner and electrified transport refrigeration to make urban distribution more flexible and sustainable.” Switching between electric and diesel operation The new hybrid single and multi-temperature solution for trucks feature Frigoblock alternator and inverter-drive technology. The nose-mount T-Series Hybrid and under-mount UT Hybrid refrigeration automatically switches between electric and diesel operation as required or necessary. This enables the transport companies to operate in inner cities, residential areas and low emission zones with the refrigeration unit’s diesel engine turned off. The system is also well accepted by drivers, mainly due to the simple and smooth transition from one drive technology to the other. The driver only needs to set the vehicle when leaving the depot and the system will switch electric and diesel modes seamlessly during the working day depending on the unit’s requirements. The T-Series Hybrid and UT Hybrid solutions are aligned with Trane Technologies’ 2030 sustainability commitments, and the commitment to reduce customers’ carbon emissions by one gigaton – equivalent to the annual emissions of Italy, France and the United Kingdom combined.

As countries around the world work to contain the spread of COVID-19 and prepare to reopen, Trane Technologies is addressing critical needs for healthier air quality in buildings, hospitals and homes and safe transport for food and medicine. The global climate innovator has seen a growing focus on indoor air quality in buildings, including hospitals and other healthcare settings. At the same time, strain on the grocery supply chain and concerns about a pandemic-driven food supply crisis highlight the vital role transport refrigeration plays in getting perishables safely to their destinations. Healthier and Sustainable Buildings “Sustainable, reliable and efficient climate control technologies matter more today than at any other time in recent history,” said Mike Lamach, Chairman and Chief Executive Officer for Trane Technologies. “Society will increasingly depend on the latest technologies for airflow and filtration, controls and remote operation, and precision temperature control for transportation. As we serve these needs, strengthen infrastructure and increase efficiency and resiliency, we are improving health and safety for people, communities and the planet.” efficient built environments Technologies such as Trane Catalytic Air Cleaning systems include special filtration and UV light systems “While there are still a lot of unknowns about how the virus that causes COVID-19 spreads, what we do know is that proper design, installation and maintenance of HVAC systems are key to maintaining healthier and more efficient built environments,” said Dave Regnery, President and Chief Operating Officer for Trane Technologies. “By ensuring proper air treatment, filtration, ventilation and decontamination, we’re helping to keep people safe and comfortable in even the most challenging situations.” Technologies such as Trane Catalytic Air Cleaning systems include special filtration and UV light systems to remove pathogens and particulates from the air in healthcare facilities. In areas with specialized needs, such as isolation rooms and operating theaters, proper pressurization and airflow keep infections from spreading. supporting emergency hospital Other healthcare facilities, such as research laboratories and pharmaceutical manufacturers, also rely on specialized climate solutions to meet strict standards in air quality. Through rental options for climate and air quality control, Trane Technologies is also supporting emergency hospital expansions and temporary healthcare facilities – even tented facilities constructed in parking lots or parks. Remote monitoring and control systems enable building operators and technicians to monitor a building’s HVAC system around the clock, and technicians can diagnose and service issues that may impact efficient operation and air quality. Efficient Food and Medicine Transport It’s important that mechanical systems are checked and maintained after long periods of vacancy" “Beyond healthcare, indoor air quality is increasingly in focus as communities begin to reopen and people return to offices and eventually places like movie theaters, gyms, and shopping centers,” said Regnery. “It’s important that buildings’ mechanical systems are thoroughly checked and maintained after long periods of vacancy, with consideration to ventilation, airflow and humidity, to ensure healthy and efficient indoor environments.” Trane Technologies is helping to address another big challenge exacerbated by the pandemic: ensuring a safe, reliable cold chain to transport food and medicine. Feeding America says that food banks have seen a 70 percent increase in demand, and 40 percent of people served by food banks are new to the system. real-time intelligence “Perishable goods require precise temperature control,” said Regnery. “Even the slightest variance in temperature can cause food to spoil prematurely or compromise the integrity of life-saving medicine. Our communities need these products, so waste is not an option.” Thermo King telematics for real-time intelligence on the status of refrigeration equipment help fleet managers make sure units are running properly and efficiently to maintain safety and quality of the shipment. Further, the company offers special air filtration systems to improve air quality in vehicle passenger cabins for public transportation, such as buses. transport refrigeration technologies Trane Technologies is sponsoring and partnering with Feeding America and local food banks Through its transport refrigeration technologies and employee volunteers, Trane Technologies is sponsoring and partnering with Feeding America and local food banks to address growing food supply shortages and to divert food waste from farms to people in need. This includes establishing pop-up food pantries to serve thousands of people facing hardship. “We have an opportunity – and an obligation – to take care of our people, serve our customers in innovative ways and put our technology to work in service for our communities. Innovating and responding quickly are key to building community and global resilience,” said Regnery. transmission and mitigation There is strong evidence from The American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE) and other sources that HVAC technologies can mitigate the risk of exposure to infectious aerosols in built environments; however, the transmission and mitigation of COVID-19 in buildings is yet to be fully tested and confirmed.
