What is the best heating system to install when renovating an old building?
When renovating an old building, it is also important to consider the heating system. There is no clear-cut answer as to which new heating system is the best for an old building. The local and structural conditions have just as much influence on the choice of heating system as the costs and the legal regulations. While heating systems with storage tanks need plenty of space, solar thermal energy needs a sunny roof, preferably facing south, in order to achieve its full potential. Some homeowners want to save costs during renovation and therefore only replace the heating system as a single measure. If the insulation is not sufficient and there is no underfloor heating, a heat pump is not always the best choice. But it is precisely these heating systems that use renewable energies and are thus on the federal government's priority list. The subsidy programmes for the purchase of new heating systems are correspondingly generous. But when choosing a new heating system for an old building, there are other interesting alternatives.
