Anyone who wants to live more energy-efficiently and decides to install a heat pump to generate energy in the home has a choice of different models. What all heat pumps have in common is that they use regenerative energy, for example from the air, groundwater or the ground, and use it for heating, hot water or both.
While a hot-water heat pump is only used for the preparation of hot water and the system is completely decoupled from the heating system, an air-water heat pump transfers the energy obtained to a water circuit, which then transports it to the heating system or for the preparation of hot water. An air-air-water pump is used primarily in passive houses and functions both as heating and as ventilation. However, for it to function, it requires controlled ventilation of the living space and the house must be completely airtight.
Likewise, there are heat pumps that obtain their energy from an ice storage tank or brine-water heat pumps that extract heat from the earth's surface by means of a horizontal pipe system. Water-to-water heat pumps, on the other hand, use the energy of water. To determine which water pump is right for your needs and for the property, an expert or energy consultant should be consulted. External factors usually do not play a role in the choice of heat pump, as they use heat from the earth and groundwater.
