Decarbonisation is gathering pace as heating technologies compete in the main European marketsMay 2021

While the heating market has been stable for most of the last decade, 2020-2021 was a decisive point for the industry, not only because of the pandemic but also the push for Green Economic Recovery. In Europe, a target of carbon neutrality was set for 2050, and before that, a significant increase from 40% to 55% in the reduction of carbon emissions by 2030. The drive to decarbonisation is gathering pace with several distinct pathways to achieve it:


Here, we are talking about electric-driven heat pumps; they are part of the “all electric” scenario for the future, which is supported by the extensive decarbonisation of electricity and the shift to all electric heating. Hydronic heat pumps are of strong value in terms of efficiency and their potential to lower COemissions.

Issues include the impact on the electric grid and the price of electricity – on average three times that of gas. Heat pumps are ideal for new build but ca be difficult in older, poorly insulated buildings.

Green gas

This scenario outlines the increasing use of hydrogen – and alternative biogas – as a heating fuel.

Current projects trial the use of hydrogen with domestic boilers at 20% / 80% mix of hydrogen and natural gas. The ambition is to increase to 100% hydrogen in the long term. Some heating companies have already developed so-called hydrogen-ready boilers. The claim is that it will be possible to switch from natural gas to hydrogen with minimal disruption, when the time is right. Several obstacles, including safety, availability, production of green hydrogen, price of fuel and products, will have to be overcome to make it a success.

District Heating and Cooling (DHC)

Heat networks are most suitable for cities and built-up areas like campuses and blocks of flats. The issue is that it is inherently inefficient to transfer hot water in a pipe compared to a boiler working in situ or an electric line. The progress of 5th generation heat networks, whereby there is no central energy centre, rather using locally available waste heat and low temperature renewable energy in bodies of water or solar energy, is encouraging.

Hybrid systems

Anything that connects a traditional heating unit with a renewable energy source can be classified as a hybrid; at its simplest a small heat pump connected to a gas/biomass/green gas boiler, the latter for those cold days. This means no need to insulate the house or to upgrade the radiators. With solar PV the cost of heating can also be reduced.

Other electric: electric boilers or electric panels, air-to-air heat pumps

New buildings generally have a very low demand for heat. For an average modern home, a heating capacity of 2kW to 3Kw is adequate – a 10-fold reduction compared to an older house. Consequently, a heat pump is a good solution. But why even a hydronic system with radiators at all? Air-to-air heat pumps, or integrated solutions of heating, cooling and ventilation (with air-purification, too) is another alternative. Also, electric boilers or electric panels are viable solutions, attractive to developers, but less so to users due to the cost of heating.

We live in changing times and in the HVAC industry two things are coming together; the two fundamental trends towards digitalisation and energy transition and companies that make heating equipment or air-conditioning are changing faster than ever before.

BSRIA Worldwide Market Intelligence study into European heating industry transition: 2020-2030

BSRIA will use its solid base of historical data combined with expert views on the developments in the heating, air conditioning and renewable markets to put forward some scenarios forecasting in which direction heating in our homes will go between now and 2030. The study will identify the winning technologies among boilers, heat pumps, heat interface units, air-to-air heat pumps and reversible air conditioning.  It will also review the likely success of hybrid systems, widely seen as bridging the gap between traditional heating systems and renewables.

We will develop two scenarios, typically a hydrogen progress scenario and an electric & DHC scenario, to account for roadmaps for the banning of gas/oil, what governments will see as the more realistic propositions, what incentives or subsidies may apply, as well as, building regulations, energy prices, demographic changes, cost of installation and running, product offering, etc.

The study will focus on Europe and initially the UK, France and Germany, with reports ready by late summer. We will then expand our research to other important European markets.
