If you have a swimming pool you can heat it with a heat pump using a special accessory.
During the months when the house is being cooled by an active cooling module, the excess energy can be used to heat the water in the swimming pool. Of course, the pool can still be heated by a heat pump without a cooling module. If you have an indoor pool, you can easily dimension the heat pump so that it keeps the swimming pool heated all year round.
By using all the advantages of the heat pump in this way, heating, cooling, and hot water are provided at the same time, all at a low cost and with regard for the environment.
