The cost of an air source heat pump depends on various factors, including performance, energy efficiency, brand and installation effort. In general, prices for air source heat pumps tend to range from a few thousand euros to tens of thousands of euros. It is also important to consider additional costs for installation, maintenance and, if necessary, replacement of parts over time. There may also be regional and national subsidy programmes that provide financial support for the purchase and installation of heat pumps. It is advisable to find out about these options in order to realise potential savings.
