Air to Water Heat Pumps

AIR SOURCE HEAT PUMPS

Air to Water heat pumps

Air source heat pumps operate by absorbing energy from the outside air as it is drawn across a coil filled with a low temperature refrigerant gas. This gas is increased in pressure by a compressor which increases it temperature. The now hot gas is passed through a heat exchanger where it transfers its heat to water for either heating or hot water. 

Air source heat pumps can be installed virtually anywhere and are quick and convenient to install. They offer retrofit homes the cheapest and least intrusive way to install heat pump technology and benefit from the low running costs.

There are two main types of Air-source unit, Monoblock and split.

A split unit will be made of two parts, an indoor and an outdoor which are connected by copper pipes containing the refrigerant. Heat Energy is transferred between the outdoor and indoor units through these pipes.

A monoblock unit as the name suggests is an all in one unit. The energy is collected in the outdoor unit and is also transferred to the water at the outdoor unit. A high density insulated pipe then transfers the energy to the house.

The style of unit should be influenced by the application and positioning of the equipment. Let our team guide you as to the best unit for your application and you rest assured you are getting the best advice.
