Product introduction:

An Air Source Heat Pump is a unit that stands outside your home and is connected to your heating system. In a well insulated home, it can take the place of a central heating boiler.

Air Source heat pumps extract heat from the outside air. They are effective all year round (even at temperatures as low as -25°C) and in a well insulated home they can take the place of a central heating boiler. For residential heating systems they are at their most effective when used for lower temperature applications such as underfloor heating, but they can be configured to cope with heating most houses, whatever the age and type of property.

Air Source Heat Pumps are an eco-friendly and cheaper alternative to oil and are often installed in new build properties in areas where there is no mains gas. Properties that have an existing oil-fired boiler can benefit from the addition of an Air Source Heat Pump, as they can be easily incorporated into the heating system to improve efficiency and reduce running costs. High output, commercial air source heat pumps are also available. Air source heating systems, with multiple units linked together, can be designed for large scale installations, as an alternative to a ground source system, where groundwork is not practical.

Because air source units do not require any groundwork, installation is quick, easy and very cost-effective.

 

 

Benefits:

 

 

 

The main benefits of Air and Ground Source Heat Pumps can be summarised as follows:

 

They save money. An Air or Ground Source Heat Pump can help to achieve significant fuel cost savings compared to direct electric heating systems (e.g. storage heating), gas boilers, oil boilers and some renewable energy systems, such as biomass boilers. Additionally, the Government has introduced the Renewable Heat Incentive for owners of heat pumps.They are an eco-friendly alternative to oil, gas and LPG. Although they require electricity to operate, the output generated is around 2.9 to 4.0 times the power input (known as the CoP or Co-efficient of Performance). If a renewable source of electricity is used, for example, photovoltaic panels, they are completely carbon neutral - and you would then not only benefit from the tariff payment for the heat pump, you would also benefit from the new Feed-in Tariff scheme on the PV panels. To secure the Renewable Heat Incentive you must have a heating COP > 2.9 Geothermal International designed systems are expected to achieve COP's as follows: Heating only up to 3.8 Heating and Cooling system - Heating only up to 4.8 Heating and Cooling system - Cooling only up to 5.8 They don't require any fuel storage space, unlike oil and LPG which require large storage tanks, and biomass boilers which require wood/pellet storage. There is also the peace of mind that there is no need to store large volumes of combustible fuel on the premises. They do not require flueing as there are no harmful emissions. Low maintenance. The basic mechanism is similar to a refrigerator, with few moving parts and few things that can  go wrong - all you need to do is keep the unit clear of leaves and debris. The most costly part in the unit is the compressor and you have the option to extend your warranty if you would like the reassurance that all parts and labour are covered in the longer term.

How they work?

Following is the working principle drawing

Heat Pumps operate in a similar way to a refrigerator – but in reverse. Heating and cooling are achieved by moving a refrigerant through various indoor and outdoor coils and components. A compressor, condenser, expansion valve and evaporator are used to change the state of refrigerant from a liquid to hot gas and from a gas to cold liquid.

 

 

The main stages of the process are as follows:

 

 

Liquid refrigerant passes through the outdoor evaporator coils at a low temperature. Air is drawn in to the unit and the temperature of the outside air causes the refrigerant to boil and become vapour. The vapour is drawn into the compressor, where the temperature of the vapour is increased to over 100 degrees. The vapour then enters the condenser heat exchanger and heat from the vapour is transferred across the coils. As the vapour cools it condenses back to a liquid, which releases considerable latent heat to the air passing over the heat exchanger. The refrigerant, which is now a very cold liquid at high pressure, passes through an expansion valve, which reduces the pressure so that the cold liquid can re-enter the evaporator and begin the cycle again.

 

At stage 4, the heat is transferred to the domestic hot water tank and to an underfloor system and/or central heating radiators.
