A heat pump extracts heat from the environment and converts it into heating energy, but requires electricity to do so. It consumes one kilowatt hour of electricity to produce 2.5 to 4.5 kilowatt hours of heat. However, in a poorly insulated house, a significant amount of heat is lost, which can cause even the best systems to operate inefficiently, leading to potential energy losses of over one-third. Economical heat pump operation is therefore only possible with good insulation.

Logical conclusion: the use of a composite thermal insulation system is the first step, especially for old buildings. Therefore, before starting any work on the heating system or the house, the most important tip in terms of the order of work is: only choose the right heat pump for your home after the professionals from the painting company have completed the insulation work!
