I live in a house with two foot thick stone walls and virtually no insulation.
We have to keep the heating on pretty much constantly from October to March. 19 degrees for an hour in the morning and from 4 till 10 at night, 14 degrees the rest of the time to maintain the heat in the massive thermal mass of the walls. If you turn the heating off when it’s cold it takes hours to get the house back up to temperature again.
I have two completely seperate central heating systems, one upstairs and one downstairs to feed a shitload of radiators. Having two boilers actually makes the house easier to heat as you can zone the occupied parts of the house and heat them at different times
You would not want to pay my gas bill.
Back in 1970, the average internal temperature of a home in the UK in the winter months was 12°C.
Yep, Can easily believe that.
My parents 1950’s council house, for most of my childhood, had no heating other than a gas fire in the living room, no insulation in the walls and single glazed Crittal windows. We used to always wake up in the winter mornings with ice ferns on the windows.
