Almost every second builder now decides for a surface heating system. It is usually a floor heating system, but also wall and ceiling heating systems are very popular. Their great advantage is that the operating costs are about ten percent below those for radiator heating. There is a lot of talk about underfloor heating – and many prejudices prove to be pure everyday myths. Nevertheless, there are also some drawbacks.
According to a study conducted by the Freie Universität Berlin on behalf of the BVF in Hagen, floor heating is not necessarily more expensive than radiator heating. “Material and labor costs are almost the same,” says BVF Managing Director Joachim Plate. If there are additional costs, the builder should inquire how this is done.
Matthias Wagnitz from the Zentralverband Sanitärheizung Klima (ZVSHK) sees a similar situation: “The installation is somewhat more expensive, but it is not particularly important for new buildings.” The higher price for underfloor heating goes back to the insulation, which is included in the price. In the case of a radiator heater, for example, the latter is introduced into the calculation of the screed, which makes its work more expensive.
