So at work today, the discussion of household heating and gas/electricity bills came up (entering winter Down Under), and I commented that we have our central heating set to 14 Celsius (approx 57 Freedoms) overnight, and off during the day/evening. We find that 14 is quite comfortable under a fluffy doona/duvet. I was warmly mocked (well natured), and informed that something closer to 24C (75F) is appropriate, day and night.

Surely not… right?

    I don’t believe the government has any running initiatives to improve energy ratings on old houses, but there are certainly standards for new builds like you would have today. Generally speaking, because the summer sun disproportionately heats up our metal roof (and our ceiling cavity is not insulated), it will get to around 2-3 degrees hotter inside than it is outside, if no climate control is used.

    The advantage on a sunny winter day, is that it can be 10 degrees outside, and 17 inside if we’re lucky :) (but of course that heat vanishes the moment the sun goes behind the trees.)

      Hotter inside than outside must be a nightmare especially to sleep.
      I manage to keep temperature around 23/24 during summer and exceptionality 26/27 during heat wave. But I don’t have AC.

      It’s a bit more difficult on winter when the max temperature of the day is 1-2 degrees and there is no sun. Radiators need work frequently to keep 18 degrees.
      I wish we would have more sunny winter days.

          Traditional houses from the 70s are usually a basement and the house upstairs.
          Basement is often half or totally underground.
          Then the wall are made with cinder blocks, empty air and bricks.
          There is chimney (not sure the term in English), so you can heat with wood, but most of the time there is central heating with Gaz or Fuel to replace or in complement.

          How is it in your country ?

            How interesting - the bricks and blocks would act as quite a good heat mass to sort of, smooth out the temperature? (And chimney is the word we use also 😆)

            Our cottage is built up on hardwood stumps, with a hard oak frame, and asbestos sheet cladding, both inside and out. The roof is almost flat, just a 2 degree incline, with corrugated iron sheets from end to end. Cheap and hollow 😀 hahaha
