Water-air heatpump implementation

Project outcome:

Air-water heat pump -based heating systems can handle the heating needs of the entire property, but it needs a support system for the coldest times.
As the outside temperature drops, the amount of heating energy obtained by the air-to-water heat pump decreases, and in the most severe frosts, either electricity or the property's previous heating system (oil, gas, etc.) is needed for support. During the heating season, however, there are only a few days when the air-to-water heat pump is not enough.
The advantage of the air-to-water heat pump solution compared to geothermal heat is the lower purchase price and the fact that it can be installed even in locations where geothermal heat cannot be installed due to the quality of the soil. The air-water heat pump solution is installed in place of or alongside the old heating system.
