We need to reduce heating energy consumption in buildings in order to achieve the climate turnaround. This applies in particular to existing buildings. Surface heating systems, such as underfloor heatings play an important role. They indeed work with lower flow temperatures than conventional radiators and distribute the heat more evenly throughout the room. This means less energy is consumed and less CO₂ is generated. For this reason, underfloor heating systems are particularly environmentally friendly.
Energy sources which protect the environment like heat pumps or solar systems often provide lower flow temperatures than oil or gas heating systems. With these forward-looking energy sources, underfloor heating systems therefore make a lot of sense.
There are different types of underfloor heating systems, in particular electrical and hot water heating systems. Almost all heating systems must be covered with a specific heating screed, which should have a high thermal conductivity and at the same time be resistant to frequent heating and cooling stages. Calcium sulphate or cement screeds are well suited for underfloor heating systems.
