Have been asked to quote a replacement boiler for main house 2 floors with good insulation, windows & doors running radiators(aprox 2600 square feet) and then the annexe at (1600 Square Feet) the annexe is underfloor heating over 2 floors with good all round insulation. existing boiler is aprox 97 KW.
are there any bullpark figures of heat requirments over 1 square meter or 1 square foot?
I dont want to spend too much time on this if the clients decide not to bother.
thanks in advance
