Heatloss of small terrace house 6.5kW ?

I've just done a heatloss calculation for a small terraced house (3.8m widex 7.4m deep x 2.4m each storey with 2.5m x 4m back addition, mix of carpetedwooden and solid floors, mostly single glazed, 50mm insulation in the roof)and get just over 6.5kW, which seems very low. I've done the calcs on aspreadsheet but cross-checked with the Myson calculator for the floor andair changes of one room, to sanity check.Does this seem right? I could put it all through the Myson to completelycross-check it but it's a lot of extra work ...tia--John Stumbles-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-|-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+

BSF, I was just doing gas, flue & commission for the client and he helped me lift it.

The Keston is 38kg. Carrying that up a light-duty home step ladder and balancing with it on the top whilst trying to hang it on the wall bracket was no joke I can tell you. If I ever put another one in, it probably won't be mounted as high as a 9' ceiling allows, no matter how good a use of space it is ;-)
