It's not uncommon on a sunny day for the interior to get up over 30*C and I have recorded 38*C in my bedroom which is verging on unsafe.
Hahaha!
Do you know how many days we had here in the 40's on the trot? At least 2 weeks worth non stop with a month of here and there cooler days. Didn't even put the AC on till it hit 35. 30 Was a cool change here only a month or so ago.
We are coming into winter now and where I am, we will get a few weeks down to zero with the occasional Minus morning temps. We got a bunch of -5's last winter and that was bad.
In some places that would be a warm winter. Mate in canada has been sending me pics of the snow Piled half way up his garage door.
I don't know how anyone could live in frozen hell holes like that but I guess they couldn't imagine living in flaming hells like I take for granted.
We have insulation standards here too but I think they would be pretty poor in comparison to a lot of places. Double glazing is VERY rare here, Maybe a bit more popular down south where it's colder but still not typical by any stretch.
I'm in the process of building an oil burning heater to offset our heating/ power bills this winter. Basing it on a 100KW spa heater. Probably only need to run at about 3Kw most of the time but will be interesting to see how it averages out.
I want to keep the place itself warm, not just the air. I think if you don't heat soak the place, the walls, furniture, floors etc you are never really warm. If I ever built there would be a lot of things I'd do, hydronicaly or maybe electric floors would be one thing.
We are redoing the kitchen and I saw something at the tile place so might look into that to see if it's remotely affordable.
If I had a bit more suitable space, I'd like to put an IBC in the house full of heated water so there was a thermal mass slowly radiating heat all the time similar to an old russian stove. by the same token the water could be cooled with a refrigerated system especially at night when temps were cooler and into the mornings. The heat really kicks in after lunch time here, Generally if you are out the direct sun the air temps aren't too bad but that sun sure fries you.
