The GAHP system can reduce costs dramatically when converting from traditional boiler technology, while significantly improving environmental performance – benefiting businesses and public sector organisations, as well as domestic consumers.
The technology works by removing energy from a low temperature heat source – the outside air – and then upgrading it in the heat pump so that it can be used to heat or cool air or water inside a building. The whole process is powered from natural gas or LPG.
The concept of absorption cooling was pioneered in the late18th century and the origins of Robur’s highly efficient gas-fired systems dates back to work carried out on domestic refrigerators for the US-based Servel company by Albert Einstein.
“GAHPs harness the properties of refrigerants to change from liquid to gas and back again in order to transfer heat. The technology provides sustainable solutions for a wide range of businesses and households,”
Among financial advantages are energy consumption reductions of up to 50% and exemption from the climate change levy. Legislative benefits include cost savings relating to the new Carbon Reduction Commitment (CRC) and improved Building Energy Certificate ratings (EPC and DEC).
Additionally, GAHP systems means reduced regulatory costs as a result of low emissions, enabling points for BREEAM assessment, and compliance with Part L2A and Part L2B of Building Regulations.
Operational benefits comprise security of energy supply through reduced dependency on electricity, low maintenance levels, easy installation and heating and cooling provided by a single unit.
ENER-G supplies GAHP systems manufactured by Robur, based in Bergamo, Italy, that deliver heating and cooling for buildings, with up to 165% efficiency. http://www.energ.co.uk/?
“Our heat pump solution, in partnership with Robur, provides a reliable, cost-effective, and constant energy source that is highly effective for industrial, commercial and residential use,” added Andrew Hill.
“This is due to the system’s ability both to save energy and increase the value of the building with its A+++ classification issued by the European Commission.”
ENER-G’s services include a free feasibility study; project design; system specification;
“While traditional heat pumps use a compressor to convert the gaseous refrigerant into a liquid state, absorber and generator systems transfer the refrigerant into an absorbing fluid and then liquefy it,” said Andrew Hill.
“This means that only a small supply of energy is required to pump the refrigerant solution around the fan to circulate the air, which substantially lowers both energy costs and CO2 emissions.”
GAHPs can be used as a direct replacement for gas-fired traditional and condensing boilers due to the ability to reach temperatures in excess of 65°C and produce hot water.
ENER-G systems can be bought at a fixed cost when all the savings are realised immediately, or through a rental agreement where costs are met through savings in energy.
