The demand for eco-friendly solutions continues to grow and covers a range of industries from transport to computing and energy.
What are heat pumps?
At their most basic, heat pumps are devices that move heat from one area to another. Domestically, heat pumps can be used to extract heat from an external source and transfer it inside where it can be used to warm the interior of a property.
Types of heat pumps
Several different types of heat pumps exist, although the two most common are ground source heat pumps (GSHPs), and air source heat pumps (ASHPs). These work in similar ways to each other, the main difference being that one extracts the warmth from the ground whilst the other extracts it from the ambient air.

So how do they actually work?
The key components in a heat pump system are the compressor, the evaporator, the condenser and the expansion valve.
The first phase is the extraction of the heat from either the ground or the air. This heat is passed into the external heat exchange and causes the refrigerant liquid to evaporate and convert into a gas. This gas is then transferred through a compressor, thereby increasing its temperature.
The warmed gas is passed over the surface of the internal heat exchanger and is circulated through the system, transferring its heat to a cold water circuit to warm the water. Once the water has been heated to the desired temperature, it is sent to radiators or underfloor heating.
