One of the options that attracted us to the Ground Sourced Heat Pump was that you could also use the return feed of cold water to cool the house in the summer. Although 2007 and 2008 have hardly been blistering summers, only three years ago everyone was talking of summers getting hotter and hotter. So two comfort cooling units were added to the heat pump order to cool bedrooms and the lounge.
But having decided to fit a heat recovery system since we bought the comfort cooling units we have to think about how we duct the whole system. After considerable discussion with those in the know, we have decided to duct the comfort cooling system separately. The Heat Recovery system has a “summer bypass” that is a thermostatic switch which cuts out the heat recover element if the ambient temperature goes over a certain level and we will set the comfort coolers to cut in at that same point – hopefully!
Of course all this means our super tilt and turn windows and trickle vents will be unnecessary and the idea of living in a house where you do not need to open windows is not going down well at present. Only by living with it will we see how it performs.
