Air and ground source heat pumps utilize energy in the air and in the earth surrounding a property to provide a heating and cooling solutions. Highly efficient compared to traditional energy sources, heat pumps can help achieve massive savings.

The heat pumps are designed for outside placement and transform an existing radiator system into an excellent, complete heating system.

FUNCTION OF THE COOLING CIRCUIT
Heat pump technology is actually based on a very simple, well-known principle. It works in a similar way to any domestic refrigerator, using a vapour compression cycle.

The main components in the heat pump are the compressor, the expansion valve and two heat exchangers (an evaporator and a condenser).

A fan draws the outdoor air into the heat pump where it meets the evaporator. This is connected in a closed system containing a refrigerant that can turn into gas at very low temperatures. When the outdoor air hits the evaporator the refrigerant will turn into gas.

Then, using a compressor, the gas reaches a high enough temperature to be transferred in the condensor to the house’s heating system. At the same time the refrigerant reverts to liquid form, ready to turn into gas once more and to collect new heat.

Using an inverter-driven heat pump compressor, the system can be regulated so that heat output matches the exact capacity required at any given time. This means the heat pump will only consume the exact energy needed, making it highly efficient.

In the summer, the refrigeration circuit is capable of operating in reverse to provide cooling on demand.

An air/water heat pump makes heating your home and hot water much cheaper. You can reduce your heating costs by up to 70%, although the exact figure depends on several factors such as where you live, the size of your house and whether or not you use the cooling function. Your initial investment is relatively low since an air/ water heat pump, unlike a ground source heat pump, does not require any geothermal drilling.

Heat pumps are so environmentally-friendly. By merely upgrading naturally occurring energy from the air outside to heat your home and hot water, it leads to much lower CO2 emissions than any traditional fossil-fuel based heating system.
