Hello everyone,
we hope to get a nice plot of land in a neighboring town in the summer, so we are currently in the concrete house planning phase. We have decided to build with a general contractor. But we are not yet sure which one. The finalists are Helma and Viebrockhaus. These two mainly differ in the design of the heating system.
One provider recommends an exhaust air heat pump and currently advises against photovoltaic systems! The other provider exclusively installs air-water heat pumps in combination with central ventilation (with heat recovery) and photovoltaics with batteries.
Since these are two completely contradictory statements for laypeople like my wife and me, I thought you might be able to shed some light on our situation.
Many thanks in advance.
