I constantly automatically log and graph temperatures and weather. Its a three bed semi, cavity wall with CWI, apart from the (very cold 9" wall utility + pantry) and double glazed. Loft I converted years ago, into an unofficial electronics workshop, accessed via a loft ladder. The loft floor has insulation under it, the loft ceiling is plaster boarded and insulated and the loft access is usually closed. I added extract fans where needed, to avoid damp. I devised a very effective dehumidifier and wall fan system for drying clothes in winter in the utility. There are no other heat sources in the house, than the gas CH. Living room has a couple of tons of stone fireplace, which I guess acts as a pretty good heat store to help even out temperatures.
Before I did all the above, it was a terribly cold draughty place, with ill fitting windows and doors. It cost a fortune just to keep it slightly warm.
It is very different now...
Our general house (the hall) temperature was recorded at 11pm when the heating went off for the night as 18.1C, out side it was -3.2C and rapidly fell during the night to -4.7C. The heating didn't fire overnight. This morning outdoors is -6.1C, at 8:53. indoors the temperature has only fallen to 16.3C. I might even nudge the heating on soon
I call that a pretty good figures for heat loss. Does anyone else bother actually logging temperatures?
