Air / Ground Source Heat Pump
Air / Ground Source Heat Pumps are becoming an increasingly popular choice for home heating. Heat pumps are powered by electricity and extract heat from the ground or surrounding air to be used to heat your home. What makes the unit so special is that it supplies more energy than it consumes. For every unit of energy purchased as electricity, several units of heat are delivered, making it up to four times more effective. They are suitable for both new build properties and retrofit installations.
Saving energy and preventing pollution
The heat pump works in a very similar way to a domestic refrigerator, utilising a working fluid driven around a refrigerant circuit containing four components - an evaporator, a compressor, a condenser and an expansion valve. The refrigerant liquid circulating within the system has a boiling point as low as -40°C and evaporates when absorbing heat from ambient air. This means it’s possible to extract considerable heat from extremely low temperatures. The resulting refrigerant gas is then compressed, adding more heat energy and raising its temperature. This heat is then passed via the heat exchanger into your home for use in your hot water cylinder or space heating.
Unique efficiency
This unique product consists solely of one neat, compact unit, complete with refrigerant. The systems are available in a range of sizes from systems suitable for domestic hot water to larger models which are suitable for underfloor or radiator heating. The heat pump is the modern way to harvest yet another natural resource - it satisfies the need to move heat from ambient air, where it’s not needed, into the house where it can become an integral part of our domestic comfort in a completely safe and reliable way.
Coefficient of Performance
The coefficient of performance, or COP, of a heat pump is the ratio of the output heat to the input supplied. A heat pump operating at COP of 3.0, will provide 3.00kW of heat output for every 1kW of unit input (energy consumed).
Heat pumps have the potential to greatly reduce CO2 emissions in the home
