Without central heating on how cold is your home?

I have readings from the Hive thermostat and other devices

14C on the 18th of Jan 2024 (6am)
unfortunately I didn't have an accurate outdoor reading but I'm sure it was less than the -1C recorded

This year I see a low of
14.9C on the 21st of Nov 2025 (7:10am)
-1.5C at the same time inside the shed
 
Dropping 1'c every 5-6 hours, new build flat. Mostly west facing windows and picks up solar gain through roof but also loses heat through it. Active ventilation keeps air flowing to remove moisture, heating water flow at 55'c and a couple of hours a day between morning and evening keeps internal temps around 18'c. Obviously needs more boost when it's colder for longer or less sun outside.
 
We don't have central heating, so I only heat the room I'm in most of the time. The rest of the house drops down to around twelve degrees, but there's obviously some heat leaking out and the heating is run in the morning and evening, my guess is that with no heating it'd drop down to only a couple of degrees above what it is outside. In summer it stays cooler inside than out. Joys of a few hundred year old house,

Eventually, regardless of how well insulated, you'll reach equilibrium with the outside temperature.

The presence of people, pets, and electronic stuff in the house as well as the input of solar energy through windows means that this doesn't apply. There are houses being built now that require no heating at all, it's all provided by these things although I'm not sure the British climate allows that.
 
Late 70s built 3 bed detached, settles out around 10-13c if the server rack is running - 8-9c if not - although it takes about 18 hours to drop from the 20~ the heatpump keeps it at normally.
 
On cold days gets to around 14c without heating on throughout the house.
Most the heat is lost through the front door as no separate passageway. No drafts but the front door gets very cold.

~19 degrees, which is shorts/t-shirt comfort zone for me. Warmer if I'm gaming or rendering. The windows get closed and heating on only when the other half is staying.
 
When it was -6°C for a few nights on the run the other year, the thermostats (set to 16°C overnight) never clicked on so I guess it doesn't dip much below 16°C?

EDIT: As someone above said though, I have a thermostat so the heating comes on and I don't have to be that cold. House is barely ever below 18°C

60's semi, we keep each other warm. Drops overnight two or three degrees centigrade. It's normally 18C when we go to bed.
 
Victorian Semi-detached Villa.

Drops to about 13-14 quickly in the winter without the heating on. I've found best way is to keep heating ticking over to about 17 and unto 19 in the evening. Burner in the lounge keeps that room in the 30s :D
 
currently 13c. i live in a terraced house. built in the 1910s. but having double glazing and a house either side stops it getting insanely cold. until the outside temperature drops below 0c. then i usually have to put some socks on
 
Without the heating on my house is freezing. It's an Edwardian house build in 1904, over three floors and with single glazed wooden windows. As soon as the heating is off the heat disappears. We have the heating on when our kids are at home. But when they aren't here then my wife and I generally keep to a couple of rooms and just warm those. I couldn't tell you what temps it gets down to.

It's quite interesting that when the colder weather starts I feel really cold. But as winter progresses my body adapts and I don't fee the cold so much. I'm guessing that growing up as a kid in the 1970's with no heating except one gas fire probably acclimatised me a little.
 
I like a warm house, So wouldn't even entertain trying to see how cold it could go. Plus its a fairly large house and would take a while to warm the bugger back up. Detached,Built 1906 Some large rooms, circa 5000Sqft In total....TOTAL...lol

Some rooms are circa 5000sq.ft?! My house is about 900sq.ft/90sq.m total :D
 
I have a digital monitor thingy, it reads about 1 to 1.5c higher than my thermostat the other side of the room due to it being on my computer desk, so it's got heat from me, the screen and the pc.

Mildly interesting I guess.
