The ground in particular is a giant energy store. A few meters below the surface it stores the sun's heat. From within the Earth's core temperatures of 6,500 degrees Celsius radiate to its outer layers. Heat pumps make use of geothermal heat, or the heat from groundwater depending on the technology. The energy stored in the ambient air is also suitable for heating rooms and for producing hot water. Heat pumps can make use of this and therefore save heating costs dramatically.
The advantages of using environmental heat as an energy source:
Requirements for the use of environmental heat:
Heat pumps can use the energy from the ground. The delivery is achieved in two different ways. Either the heat close to the surface is used, where the year-round temperature is almost uniform. A surface collector installed as a heating coil at a depth of 1.5 m extracts heat from the ground.
Or, alternatively, heat recovery is possible with a space-saving geothermal probe. The geothermal heat is removed with special ground probes that go as far as 100 metres deep into the earth. The temperature is constant all year long, at about 10 °C, which is sufficient in order to harvest the heat.

Requirements for the use of geothermal heat:
Heat pumps can utilise the ambient air and make use of the stored energy for heating purposes. Our modern heat pumps operate economically to produce heating even with an outside air temperature of as low as -20 °C.

Which energy source and therefore what type of heat pump system is best suited for your application depends on many factors. The different acquisition and operating costs are to be considered. But the individual heat pump species also differ from each other in terms of permits, promotion, and the requirements of the building.
There is no standard solution when searching for the right heat pump system. But it is not that difficult to find the system that fits your needs. Talk with your Vaillant heating specialists. They can assist you in planning the optimum heating system.
Whether you need a permit depends on the type of heat pump and your location.
