In theory I'd agree that you should insulate first. But as others have pointed out, on some older houses, insulation can be difficult to accomplish (especially true in non-wood-framed housing). In such cases it is still a better idea to use LESS energy (because of a COP above 1) to heat that space than it is to use resistive or combustion methods (which have a COP less than 1). |
