LOW CARBON, ENERGY EFFICIENT PERFORMANCE The Ecodan Hot Water Heat Pump has provided this home with an impressive COP of 3.3!*1 Furthermore, the overall carbon footprint is significantly smaller when comparing to typical gas and direct electric systems. In the last year, this Ngaio Ecodan unit has only contributed an approximate 0.60 tonnes equivalent of carbon to the atmosphere*3. When the Ecodan is compared to an equivalent capacity natural gas heating and hot water system, the equivalent carbon emissions are approximately 3.9 tonnes*3. That is an equivalent of 3.3 tonnes*3 of carbon savings with an Ecodan Hot Water Heat Pump System – which could fly an aircraft from Wellington to Auckland at least 26 times!*4 STYLISH RADIATORS USED FOR SPACE HEATING Eleven radiators have been installed throughout the home to provide contemporary space heating to the various rooms. Radiators are the ideal solution for responsive heating that can be mixed and matched to each room. Quick to heat up as well as turn down or off, radiator heating is easy to control room by room.

We just don’t think about being cold anymore.” 10
