Where the use of ground source heat pumps have been considered, but it is not possible to drill in a ground probe or install a surface ground loop on the property, an air source heat pump may well be the answer. The only space requirement is an outside wall making them ideal for apartments and homes with limited outside space. With no need for groundworks, installation costs are kept to a minimum.
Air source heat pumps work by converting the energy of the outside air into heat, creating a comfortable temperature inside the house as well as supplying energy for the hot water system. As with all heat pumps, air source models are most efficient when supplying low temperature systems such as underfloor heating.
The efficiency of an air source heat pump is measured in Coefficient of Performance (CoP). A CoP of 4 means that for every kilowatt of electricity put in, you get 4 kilowatts of energy in the form of warm water. The flow temperature of the warm water is typically between 35 degrees Centigrade and 45 degrees Centigrade; much lower than achieved by a domestic boiler. The units are perfectly capable of generating higher temperatures but the CoP suffers meaning the economic and ecological benefits may be affected. Keeping the temperature at the lower end of the scale keeps the system operating at maximum efficiency.
An air source heat pump should cover the heating requirements of a well-insulated property in all but the most extreme conditions. When used in combination with an immersion heater both heating and hot water needs should be met, the immersion heater boosting water temperatures when necessary. An outside air source heat pump working efficiently can reduce energy consumption for heating by up to 50% when compared to conventional heating systems.
Nu-Heat can design and supply your heat pump requirement. Whilst we are happy to work with any designated heat pump supplier, in purchasing from one source, seamless integration of the heat pump and underfloor heating technologies is ensured with one company taking sole responsibility for everything from design and supply with installation and commissioning by specially trained engineers.
