Heat Pumps - Air Source Heat Pump Systems

AIR SOURCE HEAT PUMP SYSTEMS

sp
Installing an Air Source Heat Pump is a straight forward and cost effective method of using renewable energy to heat a home. They operate by extracting heat from the outside air as low as -20^oC and operate very well in UK ambient conditions and at normal UK winter conditions the units still deliver excellent efficiency levels.

BENEFITS

Available from 5KW to 1000KW
COP Ratings up to 4.26 at 7^oC and 2.18 at -7^oC
Models suitable for retro fitting to existing radiator systems with water tempratures at 65^oC
Reliable proven technology first manufactured by Delonghi in 1979.
Suitable for FLATS/HOUSES/COMMERCIAL.
Multi functional HEATING/HOT WATER/COOLING/HEAT RECOVERY.
Suitable for both radiators and underfloor heating.
Simple user friendly controls.

Coefficient of Performance (C.O.P.)
At an external ambient of 7 ^oC, DeLonghi Air Source Heat Pumps can provide a COP of 4.22 this means that for every 1 kW of electricity used to operate the Heat Pump, the unit will deliver 4.22 kW of heat energy into the home. Warning! be aware that if you compare COP values they must be for the same air temprature. There are numerous air pumps on the market that have very low COP at below 0^oC and below, resulting in an inefficent system. We will always provide you with a system suitable for your local climate and will provide you with COP data for -2^oC and -7^oC.

For specific model COP data see the individual leaflets in the technical data section at the bottom of the page.

Heat Pump Myths

“They use electrical immersion heaters to heat buildings”
Incorrectly sized systems will excessively rely on an immersion heater to provide heat. This tends to become a problem when a supplier has a limited range and is specifying a product outside of its normal operating guidance ie a small unit in a very cold location. The Green Building Site utilises the DeLongi Climaventa range because it is diverse allowing us to specify the correct product to the correct location. We have access to heat pumps that produce between 4.5KW to 250KW and that are designed to work at -20⁰C.
