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 live offgrid in a campervan and do not have HVAC in the normal sense. I follow mild weather, aiming for daily highs of 65-70deg F. Because I camp in arid regions this usually means overnight lows of 35-45F. I try to avoid overnight freezes for comfort and to protect my water system.
My roof vent is set to 65F (comes on then and tries to hold that temp). The LiFePO4 battery bank is warmed to 50F. At night I use an electric blanket and dogbuddy to stay warm if needed.
If I set my winter evening thermostat to 14C my wife would have my head on a spike in the front lawn. Police be damned.
We keep it at 22C as a compromise during the day and 19 at night (since we sleep better in the cold).
18C . We live in a condo building that is well insulated so setting it any lower wouldn’t help. I agree, it’s preferable to sleep when it’s cooler. 24C in winter is insane - if you’re cold just put on a jersey or a fleece.
In the winter, I’ll accept 23C anything colder and I catch a cold.
