What is the difference between geothermal heat, ground heat, air/water heat, air/air heat and exhaust air?
Geothermal heating
Geothermal energy uses solar energy stored in rocks, soil, lakes or groundwater. Geothermal heating is a technical system for heating buildings, where a geothermal heat pump raises the temperature to a level suitable for the building’s heating system.
- Geothermal energy provides good energy savings, but requires a larger installation kit
- Environmentally friendly
- Handles your entire house’s heating and hot water needs
Ground heat
Geothermal means that a geothermal heat pump heats your home by utilizing solar heat stored in the ground. The method does not require drilling, as loops are buried approximately one meter deep and over an area of 250 – 400 square meters.
- Minimal environmental impact
- Can handle the entire house’s heating and hot water needs
Air/water heating
By using outside air, indoor heat and hot water are created. (However, this method is negatively affected at low outdoor temperatures.) The installation of an air/water heat pump requires a certain measure on the site and therefore has a higher investment cost.
- A good alternative if you cannot install geothermal heating
- Provides financial savings
- Meets the entire house’s heating and hot water needs
Air/air heating
The air/air heat pump, just like the previous method, draws energy directly from the outside air and then spreads it as airborne heat in the house and works even when it is below freezing outside. This option is particularly suitable for those who have direct-acting electricity and offers great opportunities for financial gain.
- Perfect for holiday homes
- Clean the indoor air
- Can be used in summer to provide cooling
- Great financial savings in houses with direct-acting electricity
Exhaust air heating
The exhaust air heat pump makes full sonic use of the hot air that you already have in your house and that would otherwise have been vented out. This method is both economical and environmentally friendly as the air is reused. With an exhaust air heat pump, you get both heat and domestic hot water and a simple installation without the need for intervention on the site.
- Environmentally friendly
- Recovers heat from the ventilation air
- Economically
- Requires no drilling or digging
- Meets the entire house’s heating and hot water needs
