Air Source Heat Pumps

Air source heat pumps are sited outside a property and use a refrigerant gas to harness solar energy directly from the outside air - even in temperatures as low as -20C. 

This gas is then compressed to raise its temperature and the heat is transferred to the heating and hot water system of the house.  Some air source systems also include an internal unit.

Air source systems typically have a coefficient of performance (CoP) of around 3.  That is to say, they return around 3kW of heat for each kW of energy used.  It should be noted that the actual CoP of any system will depend on factors such as efficiency of the system itself, outside temperatures and required internal temperatures.  Air source systems are generally cheaper to install than ground source as there is no requirement for the laying of underground pipes and they can often be sited where there would not be sufficient outdoor space for a ground source system.

Air source heat pumps are best suited to well-insulated properties with an efficient heat distribution system and it is not unusual for them to meet 100% of the heat and hot water demands of the household.  In other properties, it may be necessary to install a secondary heater system for times of peak demand for heat and hot water.  Either way, at Eco Energi we do not believe that one size fits all, and our solutions will be tailored to the specific requirements of your project.  Our independence allows us to select products and manufacturers that best meet your requirements for efficiency and reliability, although we generally believe that Danfoss heat pumps are best at reducing your running costs and saving energy while needing only minimal maintenance.
