The Right Heat Pump for Your Home

Heat pumps use the cleanest and most affordable energy sources nature has to offer: the ground, air, and groundwater. They extract the stored environmental heat from these sources and convert it into usable heating energy. With only a small amount of electricity, the heat pump raises this energy to a temperature suitable for heating.

Electricity accounts for just 20 to 25% of the heat generated—meaning around 80% of the required heating energy comes free of charge from nature. This makes heat pumps not only highly efficient, but also environmentally friendly and cost-effective. WATERKOTTE has developed efficient heat pump solutions for each natural heat source: ground, air, and groundwater.

Heat Sources of Heat Pumps

Depending on the system, heat is extracted from the air, the ground, or water and efficiently converted into heating energy. Each source offers specific advantages and is suited to different applications.

Heat Source: Groundwater

Groundwater is one of the most efficient heat sources available. A groundwater heat pump extracts thermal energy from groundwater and converts it into comfortable heating energy. Because groundwater temperatures remain relatively constant throughout the year, this type of heat pump operates with exceptional reliability and energy efficiency.

Heat Source: Ground

A geothermal heat pump uses the earth’s heat as a natural and renewable energy source. Heat stored in the ground is captured via ground probes or ground collectors and transferred to the heat pump, where it is converted into usable heating energy and domestic hot water—completely without fossil fuels.

Heat Source: Air

An air-source heat pump uses the heat stored in the surrounding air to efficiently heat your home. Even at low outdoor temperatures, the air contains sufficient energy, which the heat pump absorbs and raises to a higher temperature level—creating environmentally friendly heating energy.
