The efficiency of a heat pump depends on various factors that should be carefully checked. These include the heat source, the size of the radiators and the actual heat requirement. The consumer advice center points this out. In terms of heat sources, groundwater pumps are the most efficient, followed by ground source heat pumps and air source heat pumps. If the radiators are too small or if more heating is used than planned, the heat pump cannot work efficiently. Regular maintenance by specialists is crucial to ensure that the heat pump works optimally.
Under good conditions, electricity for the heat pump can be supplied by a photovoltaic system. As the electricity from your own roof is cheaper than that from the grid, according to the consumer advice center, heating costs can be reduced. However, the consumer advice center also points out that a solar system on a detached house alone is not sufficient to operate a heat pump heating system. The reason for this is that most heating is required in the winter months, but only low solar yields can be expected during this period. According to the consumer advice center, the heat pump can still be connected. This allows more of the electricity generated to be used. This is more lucrative than feeding it into the grid.
To estimate the total cost of a heat pump, funding opportunities should be considered. The federal and state governments offer various subsidy programs for the installation of heat pumps, which can reduce the investment costs. It is important to check the conditions of the individual programs and submit applications in good time. Sound advice and planning are essential in order to find the best solution for individual needs and requirements.
