A heat pump is an economical alternative to a traditional boiler. In fact, the technology produces up to 75% of the heat you need. The remaining 25% comes from natural gas or electricity.
The operation of a heat pump is simple:
A distinction is made between different types of heat pumps, depending on the heat source used and that which needs to be heated (water or air).
A heat pump extracts heat from a heat source (soil, air, groundwater) with the help of collectors.
A coolant transports this energy to a compressor. The advantage of the coolant is that it boils at a low temperature and evaporates.
In the heat pump compressor, these vapours are compressed until they reach a higher temperature than the air or water used to heat the home.
The compressor is the only part of the heat pump that uses energy (electricity or natural gas).
This heated vapour then ends up in a condenser. Here the vapour transfers its heat to the heating system of the house.
An expansion valve lowers the pressure of the vapour and cools it down again to a liquid. It is then sent back outside to evaporate, after which the whole process can start again.
