Posted in housekeeping but AIBU is the only place that gets replies 😜

If you have a baby, it's worth bearing in mind the safe sleep guidelines, which are to keep the room temperature (the room where the baby is sleeping anyway) between 16-20 C. www.lullabytrust.org.uk/safer-sleep-advice/safer-sleep-basics/baby-room-temperature/

This is what we do. 18 isn't warm enough for my soft southern bones.

Another vote for 18 during the day 15 at night. Dress baby for the temp, much healthier in my personal opinion. Off mostly between May & September ( depending on if we actually have a summer)We have Hive. Heating costs dropped by over a third when we started doing this as some days heating just on for very short time, just blips on to keep temp right. We are in a 1920s home, solid brick & though we didn't think we had a damp issue. I got a dehumidifier mostly to dry the clothes in winter. It's amazing & swear it has dropped heating bill even more keeping house at 55% humidity, which makes it feel warmer, plus costs very little to run.

Same here

I'm at home all day and get cold easily so ours is on all day at 21c. 18 would be far too cold for me

If you have a baby then 20 degrees is probably fine, but in an old house you might want to consider getting a decent dehumidifier, and run it for an hour a day.

Can control each room so 20 in rooms we're using, 16 elsewhere and overnight ( with doors closed). 20 doesn't feel warm to me but I wfh, so not moving around much during the day. Also have one of those smart thermostats that knows if anyone is home and only hears if so. Before I had that and When everyone was at school / office had a schedule similar to yours.

This is what we do.

Also agree that good ventilation and dehumidifiers help with damp.

it depends. I have got thermostatic rad valves so they are on the frost setting in unused rooms. The hall thermostat sits on 22 but that doesn't mean all the rooms are 22. I tend to do it by whether I am comfortable in a sweatshirt and joggers. Heating comes on about an hour before I get up and again early evening till just before bed time.

Ours is set at 18C and is constantly on all year round. All radiators controlled by individual thermostats so unused rooms can be turned off. Converted Victorian School but this seems to keep damp at bay. We've been here years and, for us, this is cheaper than letting it get cold and then trying to get up to temperature.
Mind you it hasn't come on yet this year and we're in the north.

We have the heating on constant at 18 during the day and 15 at night. It only comes on for a few hours a day. It's meant to be a cost efficient way of doing things and means the temperature never drops really low.

Ours is like this, we have Nest which tells the boiler when to come on and go off from a thermostat in the hall. Our settings are different from @Wibblywobblybobbly but it's the same idea - the heating is kept between a range of temperatures and therefore doesn't fluctuate wildly from very cold to getting too hot. Our heating bill actually dropped by about a third after installing Nest, rather than going up, and the house is more comfortable day to day.

Depends on the house. Our old 30s semi was set at about 22 and was on all day pretty much but because the house was damp and poorly insulated it was never warm. Our house now is set to 17. Comes on for an hour at 2am although now dc are older and don't wake up at night can probably get rid of that, the comes on at 5am, off about 8 and back on mid morning if we are home and just turn it off if we don't need it.

You just have to find out what works for you in the house.

Make sure you either turn off the dehumidifier when windows are open, or that it is running in a rokm with doors and windows closed. Otherwise it is pulling the damp air from outside through, and is pointless.

We too live in a similar property and would spend an absolute fortune if we kept it at a constant 18, unfortunately they just don’t hold the heat well, it’s a real ball ache in the winter trying to keep everyone warm, stop the condensation and keep energy bills down

I’m in an old Victorian. Make sure air bricks aren’t blocked up or covered. Almost all ours were when we moved in.

Apart from that, I set my heating to 19 constant. When it drops below 19 it’s comes on day or night. I have a little one and don’t want her getting cold in the night… it wakes her up 😂

My thermostat is set at 18oC and the heating is timed to come on for 2 hours in the morning and another 2 in the evening. We also have a log burner that I light some evenings and a dehumidifier I switch on for a couple of hours most days in the winter.

Ours was set at 18.5 for all day until 5 o'clock and it barely came on, thermostat said 18.7 when I looked, it then went up to 20 at 5 o'clock for the evening until 10

If it's not got them already, look into getting air bricks. It can do wonders for damp in Victorian houses.

Personally we didn't put the heating up with a baby, just made sure to dress baby for the temperature. Although actually it subsequently turned out baby was far too warm following the guidelines as he also runs hot. The minute he could start objecting to wearing a sleeping bag he did, and even now at 5 he largely just sleeps in pyjamas and kicks the covers off, even in the winter. Wish I'd realised sooner as I think being too warm caused a lot of his night wakings.

Anyway, that heating regime has been fine for our old house. We also make sure to open a few windows for a good half hour or so a day year round.

Just stick on a constant 17/18 for the day, 14/15 at night. It's thermostatic, no need for schedules other than day/night

That's how I'd have it with it on for a bit at midday if home and possibly 5ish

It's a really personal thing. 20 would suit me. I like a quick hour to warm up house before I get out of bed then prob same again at about 4 to warm
Up for the evening .
My house is new though and heats up fast so that will change by the house type.

Do you have a dehumifier?
