Hot water heat pump and solar system - the ideal supplement
The hot water heat pump uses exhaust air from basement and utility rooms as a heat source. The temperature at the installation locations should not drop below 10 Celsius at any time the year in order to provide sufficient heat. The heat is drawn from the environmental air by a heat exchanger - The electrical energy required for this process is provided by the photovoltaic system.
The heat pump can be powered almost entirely with free solar energy for up to 7 months per year.
A further advantage of combining a hot water pump and solar system is the possibility of heating water to as high as 60 ° C in the storage tank during sunny periods. Temperatures are normally between 45 and 50 ° C.
It's a simple calculation: If there is a lot of solar power available, the water can be heated to higher-than-normal temperatures. The higher the water temperature in the thermal storage tank, the longer hot water remains available, even when the sun is no longer shining, because it takes longer for the water to cool down again. There is also a larger amount of hot water available.
The combination of photovoltaic system and hot water heat pump assures a higher proportion of internal household consumption and lowered electricity costs.
