The Viessmann Group has announced a record revenue in 2020 of 2.8 billion euros (previous year: 2.65 billion euros). Following a global market slump at the beginning of the COVID-19 crisis, the family-owned company and its installer partners quickly consolidated and kept day-to-day life going for customers internationally, growing sales by 6 percent over 2019.

Maximilian Viessmann, Co-CEO of the family business, said, at the Viessmann Live digital event on March 22nd: "Thanks to a unique sense of solidarity among our installation partners and our 12,750 family members, we have successfully managed to continue to grow in a year of crisis. We did this with a lot of positive energy and for our common purpose: to create living spaces for generations to come. A crisis shows clearly who you are, and not who you want to be. Together and united, we have shown who we are. I am extremely grateful for the team spirit, the solidarity, and the sense of responsibility demonstrated by the entire team."

Renewable Energy-Based Climate Solution

Sales growth is largely attributed to Viessmann’s renewable energy-based climate solutions and digital services. Green climate solutions – which now account for approximately 50 percent of Viessmann turnover – include hydrogen-ready wall-mounted gas boilers, fuel cells (+8 percent), heat pumps (+35 percent), and batteries (+48 percent).

On the digital technology and services side, Viessmann saw dynamic growth in its subsidy management program, Viessmann Wärme/Heating-as-a-Service business, and both installer and end-user apps. Viessmann recorded notable positive growth in Germany, Poland, Austria, Belgium, Italy, Turkey, and Switzerland.


Viessmann acquired a stake in ThermoWise, a renowned South African commercial heat pump specialist In 2020, Viessmann acquired a stake in ThermoWise, a renowned South African commercial heat pump specialist, laying the foundation for entry into fast-growing markets in Africa.

Viessmann also expanded its product portfolio and improved market access in Central and Eastern Europe through the acquisition of Kospel in Poland, a specialist manufacturer of electric instantaneous water heaters, electric boilers and domestic hot water cylinders. A growing presence in South-East Asia involved setting up new company locations, notably in Singapore.

Viessmann has seen double-digit percentage growth in sales in the first two months of 2021.

Successful Crisis Management During The Pandemic

Viessmann’s 20 production plants around the globe continued production during the pandemic with almost no interruptions, thanks to excellent hygiene, Covid-secure working practices, and a far-reaching testing strategy, which resulted in below-average numbers of Covid-19 cases within the company.

Responding to needs outside of the core business, Viessmann embarked on various social responsibility initiatives, manufacturing mobile ventilators, ICUs, face masks, and disinfectants. Viessmann engineers developed the new Vitovent 200-P air purification system, to supply school classrooms with continuous fresh air, removing aerosols and protecting students and teachers against viral infection. In addition, the Viessmann Foundation supported more than 80 schools during the crisis with the supply of ventilation solutions, laptops, computers, monitors, disinfectants, and masks.

During 2020, Viessmann invested more than 120 million euros in its own future. Research and development focusing on hydrogen-ready heating systems and fuel cells, and holistic solutions for purely electricity-powered houses, including digital energy management. A new development center for heat pumps in Dresden, Germany, was established. Viessmann increased the number of employees by 450 to a total of 12,750.

Co-create climate for life

The theme behind the latest climate innovations Viessmann has also unveiled a number of new products, platforms, digital and other services to tackle global warming, together with specialist partners. Highlights, relevant to the UK market, include:

  • New electronics platform: a new controls system will network Viessmann energy systems – including heat pumps, ventilation systems, and electricity storage systems – with digital services to form a uniform overall system. Beyond controlling the devices, it offers simple and fast access via the ViCare app and the new Vitoguide, which now combines menu-guided commissioning, remote maintenance, and service in one digital service tool.
  • Green hydrogen readiness: Viessmann’s gas-condensing boilers in the Vitodens 200 and 100 series are already certified to operate with up to a 20 percent hydrogen mix with natural gas and can even convert a 30 percent blend into heat easily and efficiently. The next generation of Vitovalor fuel cell heating devices, the new compact Vitobloc 300 NG 15 and NG 20 CHP modules and, from mid-2021, the Vitocrossal 100 gas-condensing boiler (type CIB), can also be operated with a proportion of up to 20 percent hydrogen. Viessmann’s Vitomax hot water and steam boilers can be operated today with pure hydrogen.
  • New CHP units: The new Vitobloc 300 NG 15 and Vitobloc 300 NG 20 models will be launched later in 2021. They are compact, fully wired units with a water-cooled synchronous generator for producing three-phase power and heating water. They boast low operating noise of less than 49 dB(A) and maintenance is only required every 8,000 operating hours.

How Will Remote Working Affect HVAC?
How Will Remote Working Affect HVAC?

The practice of working from home soared during the coronavirus (COVID-19) pandemic and many observers see a likely continuation of the trend, as infection risks gradually subside. Both environments – home and office – depend on HVAC systems to keep occupants comfortable (and safe!). Therefore, the industry stands to be impacted whichever way the trend plays out. We asked our Expert Panel Roundtable: How will remote working affect residential and commercial HVAC?

Active Technologies Needed For Indoor Air Quality As Pandemic Plays Out
Active Technologies Needed For Indoor Air Quality As Pandemic Plays Out

The most likely scenario for the next 12 months in the United Kingdom is far lower risk of serious COVID-19 illness due to the vaccine. However, there will be big swings in R rates, and there is uncertainty about how effective vaccines will be against COVID variants. The ‘R’ rate is the number of people one infected person will pass a virus on to, on average. As the scenario plays out, and more companies open for business, issues of indoor air quality will continue to be top of mind. The UK cannot stay in lockdown forever, so the big question becomes: What will happen when R rates rise again? Significant illness transmission “People have become far more concerned about building safety issues because we are dealing with a deadly virus that transmits when people don’t realize they have it,” says Andrew Hobbs, CEO and founder of Surrey-based air quality and HVAC specialists Better Indoors. HAIs, including COVID, are still a major issue in National Health Service hospitals The guidance of increasing ventilation air changes and using passive systems like filters and UV has been the only mitigation for dealing with indoor air quality (IAQ) issues for many years, yet homes and offices still allow significant illness transmission, says Hobbs. Healthcare-associated infections (HAIs), including COVID, are still a major issue in National Health Service hospitals in the UK, and R rates generally rise when physical distancing measures are relaxed. Air purification solutions “It is because ventilation and passive processes do not destroy viruses at the point of transmission and until we introduce technologies that do, we will always be stuck in this loop,” says Hobbs. Better Indoors works to create the safest possible indoor environments for homes, offices, factories and on transport. Their active air purification solutions destroy viral emissions at the point of transmission – an essential feature for controlling indoor R rates, according to the company. “We are the UK’s exclusive distributor of unique technology that has been around for over 20 years and is used in millions of applications around the world,” said Hobbs. “This attribute is proving to be a key differentiator as firms race to futureproof their buildings and make their indoor spaces as safe as possible for staff and customers.” Master exclusive distributor Better Indoors is a master exclusive distributor to RGF Environmental Inc. Better Indoors is a master exclusive distributor to RGF Environmental Inc. of the United States, with a territory in the United Kingdom and Northern Ireland. Better Indoors supports agents and wholesalers, providing training and education on how to specify, install and provide aftersales services. They also have a strong relationship with various operating businesses of Volution plc for their ventilation products. Passive technologies have been strongly promoted, as have ionization-only technologies. Less well promoted have been RGF Environmental’s photohydroionisation (PHI) and Reflective Electro Magnetic Energy (REME) technologies, which have had major impact where they have been installed. Photohydroionisation mimics nature’s air cleaning process indoors by creating an equilibrium concentration of ionized hydrogen peroxide molecules throughout the indoor space. More effective process These molecules react with viruses on contact, revert to water vapor and oxygen afterwards, and are replaced with new ones from the units. The process is continuous, safe and effective, says Hobbs. REME units contain an additional process of bipolarionization for particulate agglomeration also. Products include in-duct, in-AC units and standalone, plus individual units containing individual technology pieces to complement existing infrastructures. Our technology is the safest for COVID and every single future virus that comes along" Not all potential technologies have been tested in the fight against the novel coronavirus. If they had, the resulting guidance should include technologies that kill the virus at the point of transmission, which are safe and proven with millions of users. “Our technology is the safest for COVID and every single future virus that comes along,” says Hobbs. “You cannot get a safer more effective process than one that kills a virus at the point of transmission that is not dependent on the actions of behaviors of anyone or anything.” Offering maximum protection “We have learned the main route for viral illness transmission is in the air,” says Hobbs. “It is therefore essential that we future-proof our buildings and indoor spaces to the best extent possible so they offer maximum protection for when the next deadly pathogen comes along but also to minimize common illnesses going forward. The best possible protections come from IAQ processes that physically destroy viral emissions at the point of transmission rather than relying on moving it somewhere first like all filter and UV processes.” There are very few testing techniques that properly test certain technologies" One of the biggest misconceptions in IAQ is the difference between whether a particular passive IAQ process actually works and the limitations of how it works, Hobbs notes. “This is constantly misrepresented, misunderstood, and there are very few testing techniques that properly test certain technologies.” Technologies under consideration For example, the effect and performance of UV technologies are significantly limited by line of sight, inverse square law and dwell time, but this is rarely if ever mentioned, he adds. “Yes, it works but only if certain severely limiting conditions are met,” says Hobbs. “Furthermore, the industry-accepted testing metrics are designed for passives and not active systems, and this needs to be addressed also.” None of the other new technologies under consideration, such as Far UV, will be able to destroy the virus at the point of transmission because of their already known physical limitations. “We have been arguing for months that our active technology must be made mandatory for indoor spaces because it is the only method that can stop R rate rises regardless of which variant we have,” says Hobbs.

Innovative Technologies Will Drive The Future Of HVAC
Innovative Technologies Will Drive The Future Of HVAC

Innovation is a driving force behind most industries, including HVAC. Keeping up with industry research, and looking toward the future, helps HVAC professionals to anticipate upcoming changes to the industry, and to be prepared when they happen. There is no shortage of innovation in the sphere of HVAC. I recently came across some interesting designs (and one product already on the market!) that provide a useful glimpse into the types of projects that may shape the HVAC industry of tomorrow. Large-Scale Air Purification System A new purification system on the horizon provides higher levels of purification and sanitation for large-scale applications such as hotels and other big businesses. It also seeks to protect HVAC service employees from exposure to viruses when they service a system. Rather than filter out viruses, the system destroys them with photocatalysis, which uses a semi-conductor to create radicals to zap the viruses. Photocatalysis has been around for decades but is only now becoming refined enough to provide a marketable solution. Promethium, the company seeking to bring the filtration to market, evolved from the work of two the University of Nevada, Las Vegas (UNLV) students, and a University of California (UC) Berkeley graduate. The technology can be used in several ways – from water purification to energy generation – but purifying air is the first priority. Each unit is customized for a specific application, but a “basic” standard unit starts at around $10,000 and can clean 40,000 square feet of space, enough for a casino gaming floor, for example. The project won $250,000 in a contest sponsored by UNLV’s Lee Business School and has also signed a research agreement with Purdue University. It should be ready to go to market this year. Dual-Mode Heating and Cooling Device Duke University is demonstrating the heating and cooling capabilities of nanomaterials, including a dual-mode heating and cooling device that could lower HVAC energy costs by nearly 20% in the United States if widely deployed. The invention combines mechanics and materials science to either harness or expels certain wavelengths of light. Depending on conditions, rollers move a nanomaterial sheet back and forth to expose either heat-trapping materials on one half or cooling materials on the other. Designed at the nanoscale, one material absorbs the sun’s energy and traps existing heat, while the other reflects light and allows heat to escape. Flair’s Smart Vents are DIY devices that fit into existing floor and wall register slots in standard sizes The cooling portion of the sheet has ultra-thin silver film covered by an even thinner layer of clear silicon. Together, they reflect the sun’s rays like a mirror. The unique properties of the materials also convert energy into mid-range infrared light, which does not interact with the gasses in the Earth’s atmosphere and easily passes into space after it is emitted. For heating, an ultra-thin layer of copper is topped by a layer of zinc-copper nanoparticles, which interact with the copper beneath them to trap light onto the surface, thus absorbing more than 93% of the sunlight’s heat. The “reversible thermal contact” allows users to switch between two modes of heating or cooling. The device would be especially useful in the world’s temperate climate zones that require both heating and cooling during the year – and sometimes requires both within a single 24-hour period. Do-It-Yourself Smart Vents Flair’s Smart Vents are do-it-yourself (DIY) devices that fit into existing floor and wall register slots in standard sizes. The vents control airflow across individual rooms to boost efficiency. Electronics for the low-profile devices are contained in a casing that rests under the floor level. They can be hard-wired for power or can use two C batteries. The Smart Vents work with smart thermostats and/or with Flair’s Puck cylindrical devices that include temperature control and monitoring. The Smart Vents coordinate their open/shut status depending on temperature needs. For example, the vents can be used to equalize the temperature and route heating and cooling intelligently. It can provide a solution if one room is too cold when cooling or too hot when heating. The approach is aimed at approximating the results of zoned HVAC systems at much lower costs and to replace existing wall ducts.
