Hello!
We are currently planning to build a house, and that includes finding the right heating system.
We recently visited an installer near us, and he recommended a geothermal heating system.
We are planning a bungalow of about 120 m² including mechanical ventilation to achieve a nearly zero-energy house.
Our installer recommended a heat pump from KNV with direct evaporation and a ground collector. The house and drinking water should be heated with it.
Which brand would you recommend? Should we rather choose a ground collector (how many m²?) or a deep borehole (how deep?).
I saw that KNV and Ochsner use the refrigerant R407c and Heliotherm uses R410A.
Is there a difference?
I also saw that there are MODULATING heat pumps. Are these preferable? And why?
Oh yes, and last but not least, does anyone know the price of any brand? I couldn’t find prices for Heliotherm and Ochsner online.
Best regards
Daniel
