Gosh Kevin - you have got problems. I have a bad back which bothers me even more when I'm cold - tensing up the muscles and all that, so I can sympathise in a way. How are you doing after the op?
Was visited by a bloke from ARL Air Conditioning today www.arltd.co.nz who advised that it would probably cost $12,000 to $14,000 to install a heat pump system in our 'villa' in Feilding. That would be in living room, two bathrooms and three downstairs bedrooms. The two dormer bedrooms don't really need it as the heat rises straight up there, in fact I'm thinking of living up there until we can get a heating system installed. . But it is getting warmer now. Didn't light the woodburner until 4pm yesterday in expectation of the temperature dropping in the evening.
Also got info from www.chilltech.co.nz
