We live in a house, where we have a heat pump (Wärmepumpe) and an earth probe (Erdsonde).
The probe goes deep into the earth and takes the heat from the earth. Thanks to a very clever system, we can use that heat to make hot water and to heat our house. Because the heat from the earth is renewable, the system is very ecological. Before the pump and the probe we had to heat with oil, which is not good for our environment. The change to the new system is a very important step for our family and our ecological footprint. More and more families and houses change or already have changed to this ecological system.
In the picture below you can see our boiler at home.
