But why, oh why, is it even hotter at night when the air outside is cooler than it was in the day? In the day time your part of the earth is, by definition, facing the sun. As such the gravitational pull of the sun basically pulls the skin of the earth closer to it. By default, this pulls the skin or crust of the earth further away from our throbbing hot metallic core. At night, facing away from the sun, the crust relaxes, flops back down closer to the molten core and the heat comes from underneath you. This gives the impression of heat stored in the dense building materials during the day, being released at night. Link to comment Share on other sites More sharing options...

When Percy and Mary Shelley went with Byron for their Italian jaunt (where she wrote Frankenstein for a bet), the locals were bemused by the stupid Brits' behaviour. Not only did they sit out in the midday sun and ended up looking like tomatoes, they kept the house windows and shutters closed at night, and left them open all day. When any Mediterranean resident could have told them that the idea was to do the exact opposite - keep them closed all day to keep the sun out, and throw them open at night to let the cooler air in. 4 Link to comment Share on other sites More sharing options...

Stevo985 Posted June 16, 2022 VT Supporter Share Posted June 16, 2022 On the subject, my flat is so so **** hot. I know everyone is warm in weather like this, and I don't complain about the weather, I like it hot. But we must have the best insulated flats in the world. We never have to have the heating on, even in the winter. And at the moment it's just unbearable, it was 28 degrees in the flat yesterday. I've had to invest in a proper high end fan this year with the new baby as don't want to risk him overheating Link to comment Share on other sites More sharing options...
Genie Posted June 16, 2022 Share Posted June 16, 2022 (edited) I assumed it’s because our houses are designed to retain heat, once it’s in they do a decent job of not letting it escape (although insulate Britain might disagree).

Modern houses, perhaps. We have a 1910 house, built of stone. The theory is that it should be cool in summer, warm in winter. Well, it is cool in summer, fair enough. But it's feckin FREEZING in winter, costs us a fortune to heat, even before the current price hikes. 2 Link to comment Share on other sites More sharing options...

Ours is a modern house and it’s bloody boiling in the summer but on the flip side doesn’t cost a fortune to heat in the winter. Link to comment Share on other sites More sharing options...
Seat68 Posted June 16, 2022 Share Posted June 16, 2022 My last house was built in 1888 and it was never warm. Great in the summer but absolutely dog shit in the winter. This one is 1950s and seems pretty good. Link to comment Share on other sites More sharing options...

PussEKatt Posted June 16, 2022 Share Posted June 16, 2022 IMHO its all to do with what your body gets used to.Here in Perth,my comfort zone is 24 to 35 digrees.If the temp goes above or below that I/we have to turn on the heater/aircon. 2 Link to comment Share on other sites More sharing options...
StefanAVFC Posted June 16, 2022 Share Posted June 16, 2022 Our upstairs is roasting because it’s all built into the roof and our heat pump doesn’t really cool that much. We end up just turning the pump off most of the time for heating. We also have AC in our bedroom which helps a lot. Link to comment Share on other sites More sharing options...
sidcow Posted June 16, 2022 VT Supporter Share Posted June 16, 2022 Our house was built 1960 but has had cavity wall insulation and obviously the loft is insulated. We're getting new double glazing to the front as the current panels are very old and mostly broken down. Hopefully should make a difference next winter.

We can feel our loft AC down two flights of stairs! 1 Link to comment Share on other sites More sharing options...

They've lost a few inches internally but their walls are now lined with insulated plasterboard. They're hoping their usually freezing house will now be warm.
