Air Source Heat Pump Technology

A heat pump produces hot or cool water by increasing and decreasing gas temperature inside the compressor: when gas is pressurised it produces the heat, when gas pressure is decreased, the temperature decreases as well. This relationship between pressure and temperature is the main principle behind how a heat pump works. The R32 refrigerant gas then transfers the temperature to the water via a heat exchanger. Electricity is needed to run the compressor. The performance of a heat pump is assessed by using CoP (Coefficient of Performance). A CoP of 4.75 means that for every unit of electrical energy the heat pump draws from the mains electricity supply you get 4.75 units of heat energy into the property.

Types of Heat Pump

The Air to Water Heat Pump: Air to water heat pumps transfer heat from air to hot water that can be used for central heating, cooling and hot water, air sourced heat pumps are the most common and popular type.

Ground Source Heat Pump: Ground source heat pumps’ pipework are buried underground in boreholes or horizontally in trenches. Ground source heat pumps are more efficient than air source heat pumps, but require a lot of external space and additional groundworks, and as a result are generally more expensive.

Air to Air Heat Pump: Air to air heat pumps are usually used in smaller properties. They work through fan coil units installed in different rooms for both heating and cooling. This type of heat pump does not provide domestic hot water.

Types of Air Source Heat Pump

Monobloc Heat Pumps: Monobloc heat pumps are self contained and only need water and power connections to provide heating, cooling and hot water. To produce the hot water you would require a specially designed hot water cylinder that will work with heat pumps, it has to have an internal heating coil area of no less then 2.5 m/sq (ie a larger area than an ordinary hot water cylinder).

Split Heat Pump: Split heat pumps have 2 separate units, an external unit and an internal unit. The external unit can be installed 75 meters away from your property. The external unit contains a compressor and the internal unit contains a heat exchanger and a circulation pump.

Monobloc heat pumps are the most popular models installed in the UK market. We are at the forefront of the industry and our monobloc heat pumps are designed and developed to high standards with new heating and cooling technologies. In the meantime we are working on development of new range of split heat pumps to accommodate future clients with particular requirements.
