The use of heat pumps to heat water in new and existing buildings is becoming increasingly important. They represent a sustainable solution that uses renewable energies. The domestic hot water or hot water heat pump, a form of hybrid heating, can be particularly useful in existing buildings. The energy advice service of the consumer advice center points this out.
For unrenovated old buildings, the installation of a domestic hot water heat pump is a first step towards reducing fossil fuel energy consumption. In existing buildings, domestic hot water or hot water heat pumps offer a cost-effective and environmentally friendly alternative to conventional instantaneous water heaters, boilers or combi boilers. They achieve an annual coefficient of performance of between three and four. This means that they can generate three to four kilowatt hours of heat for every kilowatt hour of electricity.
A suitable installation location is crucial for the efficiency of the hot water heat pump. Ideally, rooms with a relatively high air temperature are suitable. The purchase costs of a hot water heat pump are between 2,000 and 3,000 euros, plus possible installation and assembly costs. The energy advice staff at the consumer advice center are available by telephone on 0800 809 802 400 for further individual, provider-independent and free advice.
