Thermally-driven heat pumps

Home 9 Heating technologies 9 Thermally-driven heat pumps

Thermally driven heat pumps use the renewable energy stored in the soil, groundwater or the environment for heating purposes. These heat pumps use fuels such as natural gas or green gases as the source of energy to transfer heat from the environment to the interior of buildings. Because they make the most of already existing heat, these heat pumps are very efficient.

There are three main technologies of thermally driven heat pumps, depending on how environment heat is transferred from the outside to the inside of the building: by compression, adsorption or absorption. Each of these technologies is particularly well-suited for certain applications:

      • Thermally driven compression heat pumps are especially suited to commercial buildings (such as hotels, hospitals or schools) and large housings to produce heating, cooling and domestic hot water.
      • Absorption heat pumps are well suited not only for new builds, but also for existing buildings. This is because they can very efficiently heat water, up to high temperatures. This characteristic makes them suitable for renovation projects where the original old types of radiators – called high-temperature radiators – have to be kept.
      • Adsorption heat pumps are most efficient in new heating systems or in deep renovation where they are coupled with low-temperature radiators or surface heating system.


      In recognizing the importance of this new and innovative segment of the heat pump market, the European Heating Industry and the European Heat Pump Association worked together on the report “Thermally driven heat pumps – How they work and why they matter”, provide an insight into the various types of thermally driven heat pump technology and explaining how it works.

      We also co-organized a webinar, to discuss this new and innovative technology as presented in their recent report, and then focus on the role of thermallydriven heat pumps in the decarbonisation of heating and reaching climate neutrality by 2050
