Case Study This property in Perranporth, pictured below, shows why heat pumps and underfloor heating are an ideal match for new builds. A Grant Aerona³ air source heat pump was selected as the heat source alongside a new hot water cylinder and an underfloor heating system which have been installed to meet the space heating and hot water demand of this sustainably built home. Based in Redruth, Tom Smith Plumbing and Heating Services, are G1 Installers and completed the installation. “The clients gave us a design brief and we came up with a system to suit the needs of their property,” says Tom Smith, the installing engineer. “Being an eco-friendly build, this property needed a sustainable heating system that would help the client achieve a low carbon footprint. The Monowave cylinder and 10kW Aerona³ heat pump were coupled with Uflex underfloor heating.” The 10kW heat pump is one of four models within the Grant Aerona³ R32 air source heat pump range. Monobloc in design, the Aerona³ heat pumps are inverter driven units and are highly efficient, achieving an ErP rating of A+++. The 10kW model’s excellent performance is marked by its high SCOP value of 5.22, demonstrating its efficient operation even when external temperatures are low. www.grantuk.com T R A I N I N G I N S T A L L A T I O N
