GAHP (Gas Absorption Heat Pump) - Introduction of the technology

Similar to any heat pump (use of a cold renewable source to heat the building), but the compression is replaced by a thermally reaction driven by a natural gas burner

GAHPs avoid energy expensive conversion of primary energy needed for EHPs. Therefore GAHP can obtain outstanding values of renewable energy use and reduction of primary energy use, They are mature solutions for the markets of collective dwellings and light commercial buildings, First available results from development projects in domestic market are very hopeful in term of seasonal performances, Special effort has to be maintain for regulation, standard, certifications aspects, and lobby at European level.
