Worcester has added to its range of renewable technologies with the introduction of a new collection of Greensource air-to-water heat pumps, offering homeowners an alternative option for ‘greener’ home heating with minimal CO2 emissions.
The technology inside an air-to-water heat pump works on similar principles to a domestic fridge. An external fan draws air from outside the building into the unit before converting the latent heat within the air into useable heat for home. Designed to work with existing wet central heating systems, Greensource air-to-water heat pumps transfer the converted heat into water to deliver low-cost, energy saving heating and hot water all year round.
Worcester’s air-to-water heat pumps are also ideal for use with underfloor heating and oversized radiators. Even though the heat pump can operate at up to 65oC flow temperatures, it is more efficient when operating on lower temperature heating systems. However, even really cold air can be converted into heat, as the Greensource system is capable of working efficiently in outside temperatures of up to -20oC.
When properly installed, an air-to-water heat pump can produce up to approximately four times more heat energy for use in the home than the electrical energy it consumes. Greensource air to water outdoor units have a COP (Coefficient of Performance) of up to four, which means each heat pump is capable of providing up to 4 kW of energy for every kW used.
A choice of three outdoor air to water units is available from June 2008 – 6kW, 7kW and 9.5kW. And to complete the package, Worcester has also introduced a Greensource Integrated Cylinder for indoors with compact dimensions and a storage capacity of 151 litres.
Worcester’s Greensource air-to-water heat pump and integrated cylinder will be available from June 2008 and will soon be followed by the introduction of an air-to-air heat pump this autumn.
All air source heat pumps in the range are covered by a comprehensive two-year warranty (terms and conditions apply).
