Partial solar room heating

The partial-solar room heating with both 1000 litres buffer storages covers the annual room heat requirement up to 40%.

Additionally,  passive utilization of the solar energy by means of the large south-facing lateral windows, affects the energy balance very positively.

Due to costs and implement reasons, the radiators were left as the heat emission system in the entire house. The preset- temperature could be lowered to 30 ° C, which takes better advantage of the comprehensive thermal insulation of the entire building. Thus the solar facility will essentially be better used.

In very rare cases, the solar energy may not be sufficient. Then it is reheated either with wood or with natural gas using a gas-burning-value-boiler.
