Your thermostat temperature?

So it’s cold and in our home the annual heating debate has begun. Dh thinks it’s acceptable to have the thermostat on 16. I would be far happier with 20 but we have compromised at 18 although he still complains about this and the cost.

We have a log burner which does heat the downstairs quite well but when we go up to bed it’s freezing. He doesn’t feel the cold like me and I genuinely dread this time of year and having to argue just to feel warm in my own home.

Get an electric blanket for your bed. You can get one with 2 different sides and leave his off and turn yours on.

Between 18 and 21 depending how I’m feeling, but that’s only when it’s on, we don’t have it on all the time. I’ve just set up a scheduled for a few days given this cold snap but generally we turn it on just on the mornings and evenings we need it. Though recently been experimenting with leaving it on overnight in case it helps our two year old sleep.

Had the heating in for 7 hours today, never normally have it on that long as cant affors it
Normally only have the heating on for 3 hours a day

I came to realise that when it’s colder outside, my thermostat had to be increased for the house to be warm. I didn’t understand it because, like you, I assumed if the thermostat was at 20c, the room would be that temperature irrespective of the temperature outside. It turns out that the colder the weather, the quicker a house loses heat. When it’s very cold that loss happens fast enough that the thermostat needs to be increased in order to maintain the 20c!

The thermostat will tell the boiler to stop heating when it gets to 20 degrees inside regardless of the temperature outside or the rate of heat loss. If it can’t maintain 20 degrees then the boiler and/or the radiators are undersized. Turning up the thermostat won’t fix that.

  1. We have a giant African land snail who gets very upset and tries to push his guts out of his mouth if it gets too cold.

I have been on many many nanny MN threads for over 2 decades & this has to be the funniest & yet understandable reason ever. I'd never turn the heating down 'just in case'. 😂😂😂

Anyahyacinth · 21/11/2025 00:18

18 degrees, no heating on at night ever

Mademoidame · 21/11/2025 00:17

18 during the day, 15 at night. I turn it up occasionally if I'm cold and do turn selective radiators off/down depending on where I am in the house. We have a log burner which we usually use during the 3-4 coldest months. Currently -3 outside but the heating is off so it hasn't gone down to 15 in the house yet. Our heating costs a fortune but the house is old and draughty and I can't bear being cold.

FullOfMomsense · 21/11/2025 00:09

22° overnight, one dc runs warm so slightly cooler for her room. We are blessed to sleep in a warm home

ghostiewhisp · 21/11/2025 00:06

Mine is staying on tonight, I’m cold. It’s set to 16.5 for tonight
usually around 18c if I’m awake

I don’t work hard. I only work frontline in NHS and lone-parent in my downtime.

Which is why I only deserve to have my house at 10.5 degrees by day.

I’m genuinely sorry. I didn’t mean to sound so insensitive.

nocoolnamesleft · 21/11/2025 00:05

19 in the morning and evening, much lower the rest of the time when I'm either out or in bed.

I do night feeds, pretty cold sat still and topless in the middle of the night while my baby feeds. My baby doesn’t want to
go down when it’s cold either. Not a waste of money to me!

Yes, it's almost like people have different situations & needs isn't it

😂😂

21° at all times.
We all work too hard to be cold in our down time. Fuck that noise.

I can’t afford to have my heating on other than evenings. Today whilst WFH ringing patients this was how cold my house was.

Mine's hard wired in so not easy to move at all and I suspect my LL would take a very dim view of me making any alterations to their house.

I don't think it actually matters anyway. You get used to what yours needs to be set at for your home to be comfortable (if you can afford to do that) I actually have a wireless one I can move around & find putting it in the bedroom
on a low setting with the radiator on very low means the rest of the house is a more steady comfortable temperature.

WhatATimeToBeAlive · 20/11/2025 09:06

19.5 - but it's never on at night. I don't understand anyone that has the heating on overnight. What a waste of money.

Some people have health problems, or are elderly and need a warm room. Does that help you understand it!

Elbowpatch · 20/11/2025 09:04

I’m not making sense? You have turned it up from 18 to 20 so it won’t get colder, it will stay at 20.

I have a child who is now on palliative care, his body thermostat struggles to maintain a normal temperature and he often drops to 35.7 overnight and to help him keep warm the heating comes on when the house drops below 20° day or night.

Biggest Hugs.

thats a sentence no parent should ever have to say or write xx

making him as comfortable as you possibly can is the only thing that matters

this random on line sends you much love

CrazyCatMam · 20/11/2025 23:33

16 when I go to bed (it was at 14 but we’ve had snow and wind here), 18 through the day & 20 in the evening. Teens have wee plug in heaters if they want their rooms warmer than that.

Old house, but we added insulation and double glazing. Once the house reaches the temp and the heating cuts out, it tends to maintain that temp for a decent while, so often it’s not on at all.

Namechangefordaughterevasion · 20/11/2025 23:31

18 during the day. It goes off at 9pm and comes back on at 7.30 in the morning. I can't sleep if the room is warm.

PaisleyGilmourStreet · 20/11/2025 23:13

21 round the clock for us. It's been very frosty out the last couple of days, so I've had it at 22.5 for a few hours by day. I imagine we'll be paying more than usual on our DD for a bit this winter (I've been using the tumble quite a bit too), but needs must.

18 is a minimum according to health professionals

out thermostat is set at 19 - the living room runs therefore at 20 or 21 and the upstairs at 18

turn it to 13 overnight - from around 9 till 7 but so far it doesn’t need to operate overnight

18 would be nice.

17-17.5 here in the day. Off at night.

I'd prefer warmer really.

GrannyTeapot · 20/11/2025 22:55

Disabled child and parent here. I don’t quibble with the cost - thermostat is set to 22 at all times. We have a log burner that tries to heats the house too, but it is a poorly built and draughty place that is right on the Atlantic. It’s never as warm as I’d like it to be, and loses heat so quickly.
