What pump is more suitable for me – air-to-air, air-to-water or a geothermal heat pump?

It depends on your needs, which pump type you should choose. If you want to get warmer in a specific room or smaller apartment, heat buildings that you use temporarily or support existing heating system during cold periods, then you need additional heating, air-to-air heat pump suits here better.

If you need a complete heating solution for a new house or you want to replace the existing heating solution in full, an air-water or geothermal heat pump is more suitable. The latter two also make it possible to heat household water and are an ideal solution for basic heating in larger households.

How much can you save by selecting a heat pump?

If you use electric or oil heating to heat your home today, you can save more than four times more on average electricity costs with a ground source heat pump, and almost 2-3 times with an air-to-air heat pump and an air-to-water heat pump.

What are the advantages of a heat pump over other heating systems?

If you heat your home with electric fans or radiators, the heat pump will have significantly lower heating costs and a longer service life.
