Helpful guide for private builders

The Bavarian State Office for the Environment (LfU) has published a guide to dealing with noise problems caused by the installation of air-source heat pumps in private houses.

During the preparation of the guide, it also came to light that there are considerable differences in the quality of individual products in terms of noise. After all, if all components of an air-source heat pump are optimized in terms of noise, the sound power level should be no more than 50 dB(A). In fact, however, the sound level of equipment on the market can be 70 dB(A) and above.

Depending on the insulation quality of the house and the height of the flow temperature, a wall heating system needs between 20% and 35% of the living space. However, this is not the only difference to underfloor heating, which generally requires one hundred percent of the living space.
Underfloor heating systems react more slowly to climate changes, require higher flow temperatures and cause dust swirling. As a result of the smaller area requirement, the client saves installation material for wall heating systems, thus lowering the production costs. Wall heaters radiate radiant heat and can be combined with clay or lime. You will find several reasons to deal with this technique in more detail.
