We recently installed a Sanden Heat pump. We chose Sanden for a number of reasons including it being quiet. However, we were astounded at how quiet it actually is. You had to listen hard to hear from only a few metres. It is amazing.

Want an energy efficient house? When we finally found a builder prepared to tackle an ICF build he sent us along to LAROS – and that changed our world! Andreas took 20 minutes out of his busy schedule to sit us down and tell us about ‘Passivhaus’ design – we never looked back. R6 insulation at roof level wrapped in a gortex shell, taped down to make it airtight and big, beautiful, TRIPLE glazed windows and triple sealed doors from Germany. The heat exchange ventilation systems keeps us warm in winter and keeps the heat out in summer. The Sanden heat exchange hot water system and the 5KVA Solar system means power (and gas) bills are a thing of the past. We love our comfortable, economical, quiet (seriously) house. If you’re thinking brick veneer don’t sign until you’ve heard about passivhaus.

We’ve been in the house for 2 months now, and through warm sunny days, gloomy days and overnight temperatures of -6oC, the house has really shown that it is delivering on the promise. The temperature has not dropped below 19.2 degrees (even with the freezing nights) and has stabilised at a comfortable 21-23 oC during gloomy days and cool nights. The higher temperatures due to the solar gain on sunny days are easily managed through opening the clerestory windows in the living room and tilting other windows throughout the house to manage a very comfortable temperature.
