Air and Ground Source Heat Pumps

Air and Ground Source Heat pumps are the most efficient alternative to coal fuel, oil and electric systems in terms of both heating and cooling domestic and commercial premises.  Whilst gas is relatively efficient, it is not a long term solution in terms of reducing the carbon footprint.  Properly installed,  heat pumps can supply more heating and cooling capacity than the amount of electricity it takes to to run them, and can often attain more than 300 per cent efficiency.

Air Source Heat Pumps

Can provide fairly low cost space heating. A high efficiency heat pump can provide up to four times as much heat as an electric resistance heater using the same amount of electricity. The lifetime cost of an air source heat pump will be affected by the price of electricity compared to gas or oil.  At Nexiom we provide a cost comparison with all our surveys. An air source heat pump issues no carbon dioxide, nitrogen oxide or any other kind of gas. It uses a small amount of electricity to transfer a large amount of heat: the electricity may be from a renewable source. A  domestic air source heat pump can extract useful heat down to about −20 °C.

Ground Source Heat Pumps

Depending on latitude, the temperature beneath the upper 6 metres (20 ft) of Earth's surface maintains a nearly constant temperature between 10 and 16 °C (50 and 60 °F) Geothermal pump systems reach fairly high coefficient of performance (CoP), 3 to 6, on the coldest of winter nights, compared to 1.75–2.5 for air-source heat pumps on cool days. Setup costs are higher than for conventional systems, but the difference is usually returned in energy savings in 3 to 10 years.
