Résumé

Ground-source heat pumps (GSHPs) were shown to use between 15 and 20% less energy than an air-source heat pump for a 200 m2 house built to the proposed revised NZ Building Code insulation levels located in the lower North Island or South Island. With present energy prices, this energy saving struggles to justify the extra cost of a GSHP even for a house in Clyde which had the highest heating load. It is expected that GSHPs would be more economically attractive for applications with larger heating and cooling loads or if the option to heat water with a desuperheater is included, so further investigation of their use in NZ for such cases is recommended.
