Hello all,
I've been finding your experiences and wealth of knowledge fantastic during the fantasy phase of our project - thank you - but now it is getting real I was hoping for some more specific guidance.
We've bought a 1970s chalet/bungalow in north Devon and will be converting and extending it to provide a zero net energy home to retire to. It is on a NE sloping site and will have living spaces & main bedroom on the 1st floor (with 3 more on GF). Our architect has produced some great plans for about 165 sqm and the 1st pass of the PHPP says it will just about meet the EnerPHit standard. The calculations indicate that a couple of small radiators and a towel rail attached to an ASHP will be enough, but I have read enough on this forum to believe that UFH will be better. However I'm a little concerned whether our inverted arrangement affects this: with a concrete slab on the ground floor and the bulk of the thermal mass in the original GF walls, does this affect the logic of the heating plan? (The GF will not be much used unless the kids & grandkids are visiting). Also, how do you control the system to distribute heat/coolth around?
Thanks in advance for any input.
