An Air - Water is a very energy efficient and environmentally friendly way to generate space heating and hot water. The heat pump uses outside air to warm your house in the winter and cool it in the summer. This system can deliver in excess of 70 % saving on energy bills when compared with the more traditional oil boilers.
In a simple way, the heat pump is a device that “transports” heat energy from one place to another place.
The heating process starts in the outside unit. The surrounding air is passed over an evaporator which contains refrigerant. The refrigerant is responsible for transferring and transporting the heat. Then the refrigerant is passed through a compressor which significantly increases its pressure and temperature. The heated refrigerant then flows into the heat exchanger (indoor unit) where it transfers its heat to the water in your heating system.
With the heat pump, cooling is also possible. For cooling, the
