Bockenfeld, Germany

Oil out, air in!

Replacement of an old oil boiler, built in 1984 and a domestic water heat pump.

An efficient heat pump AERO SLM 6-17 from iDM was installed with a targeted annual performance factor of 1 to 4,2 so the heat pump can also work efficiently, a hydraulic balance was carried out on the existing underfloor heating, this is also mandatory if you want to have the subsidies from BAFA.
On the upper floor, 4 radiators were enlarged to reduce the supply temperature from 70 to 48 degrees at an outside temperature of -14 degrees, which in turn helps to save electrical energy.

House year of construction: 1888!
