The heat pump is one of the most efficient and environmentally friendly heating systems of our time. It uses the energy stored in the environment and converts it into heat for your home. But how exactly does it work? In this article, you'll find out everything you need to know about how a heat pump works - explained simply and to the point.
What is a heat pump and how does it work?
Find out everything you need to know about the definition, functionality, benefits and cost-effectiveness of a heat pump below.
Definition
A heat pump is a heating system that absorbs thermal energy from the environment (air, water or earth) and makes it usable for heating, hot water and sometimes even cooling through a technical process.
How it works in 4 steps:
1. energy absorption from the environment
The heat pump extracts energy from the environment:
- Air source heat pump: Takes heat from the ambient air.
- Ground source heat pump: Uses the energy stored in the ground.
- Water heat pump: Taps energy from groundwater or other water sources.

2. compression of the refrigerant
The refrigerant in the heat pump absorbs the energy and evaporates. A compressor then increases the pressure, which heats the gas to a high temperature.
3. energy transfer to the heating system
The recovered heat is transferred to the heating system. The refrigerant condenses and becomes liquid again.
4. cycle starts again
The cooled refrigerant flows back and starts the process again. In this way, heat is continuously generated.
