We live in a old granite cottage with tiny windows, no wall or floor insulation, very little roof insulation left (squirrels have had it we think), no central heating just range and wood burner. So, I'm in three layers at the moment and have had the fire going for nights now, DH moaned he was too warm last night! Off out soon to do more wood sawing. That will warm me up and build up the supply we get through by the wheelbarrow full.
Fortunately, we've almost finished building our new south facing house with masses of insulation, heat recovery system and big south windows.
