Overnight heating??

BooJewels

I woke just before the heating switched on this morning, so had a quick squiz at the Hive app just as the heating was switching on and the thermostat was recording a temp at that point of 15.7°C.  That's downstairs in the hall and the upstairs is usually a degree or two warmer than downstairs, so I'd guess my bedroom was about 16°C.  I thought my house was poorly insulated, but maybe the thick stone walls are better than I thought.

Heating goes off at 10pm and doesnt come back on until 6am.      No need for heating outside of those hours as the residual heat after 10pm is fine until bed time and the bed keeps you warm until you need to get up.

I am considering dropping 30 minutes off the night time heating as the residual heat is sufficient until about 2am.

Thermostat set to 15 overnight. Hasn't yet got that low, but expect it will this week. Down to 15.5 first thing this morning before heating kicked in at 7.

To those that don't run heating through the night, what sort of bedroom temps does your rooms drop too in the night?
Do you not get condensation etc when you wake up?

My bedroom is the coldest on the outer north side of the building, two windows and two outside walls.  [The other two bedrooms are on the inner wall (semi-detached house), one outer wall and window each; they're also above the sitting room which is the warmest room in the house with two radiators and my brother's computer.]  I don't know what my bedroom gets to but I wake up long after the house is up to a reasonable temperature again, no cold noses here thankfully.  Downstairs last night at 3am the thermostat said 16.5℃, although of course there's scope for the outside temperatures to get much colder still. 

We do get condensation, there's often a lot of it by the evening anyway.  I don't know what it's like early morning.  But as I said in my previous post, we used to get frost on the inside so unfrozen condensation is a heck of an improvement

For all our house seems to be a bit colder than others on here (internal temps dropped below 18℃ a month / month and a half before many other posters' homes) it doesn't seem to lose heat ever so quickly now that the fabric of it warms up with central heating.  It gets chilly, but not cold like the temperatures you're seeing.

Thanks for your input; I was just genuinely interested to know if/how trends have changed since I was a kid.  Absolutely no judgement of anyone is to be implied from my original posting

It's at least partly due to the products available nowadays. Smart thermostats can set different temperatures at different times.  Back in the days of my childhood people would typically just have a thermostat and a separate time clock. I don't know how many went to the trouble of adding a frost stat, or rigging the time clock to switch between two different thermostats.

How is it flued currently? 

Straight up a vertical flue that runs up a brick chimney straight out to the roof. House was built in the early 1950’s

I wouldn't have thought that replacing it with a modern floor-standing boiler would be a problem then?

Our heating is 'on' 24/7/365.  It's set to kick in if the temperature gets below 15 degrees overnight.  I think that's probably only happened on a handful of occasions in our 37 years ownership of this house.  I love the feeling of cold sheets and hate a warm bedroom.  We have the upstairs windows open 'on the latch' the whole time.  We 'lock them open' when we go away on holiday - no problem and the rooms still have air circulating whether it's summer or winter.

Heating on from 5:30 - 21:00 at 18 degrees. Then 15 degrees from 21:00 to 5:30.  It needs to be fairly cold overnight before it kicks in, and that only lasts between 11 and 15 minutes. Hive says it was on 3:57 to 4:00 this morning.  

A couple of reasons for that, one is in case we get up during the night, and the other is that it takes a long time to heat up to 18 in the morning anyway and if it drops below 15 it would take even longer. Last year we had a couple of slots at 20 degrees, roughly 5:30 to 9:00 and 16:00 to 21:00, with 18 degrees in between, but this year we've cut back to 18 for the duration.

If you have a concealed flue, there needs to be access hatches so that joints can be inspected. Without hatches, a GSR engineer could slap an "at risk" notice on the boiler and disconnect the gas supply.

I'm in an all electrical flat. It can get very cold despite new windows and funded insulation. Even with windows on latch which they are in some rooms 24/7 , I wake up to condensation on those windows. I have a hard time finding a balance of heat/ventilation here. The bedrooms have panel heaters. My daughter's room can go down to 10 deg at these coming due temps during the day. I feel with how cold her room gets, I have no choice but to run her panel for a few hours through the night as it uses cheap rate electricity too then and if ran for more than a few hours, even after once it is completely off by 7.30am, her room stays in regions of up to 13-15 degrees by 1-2pm until it then drops more to about 12-10 deg by 4 or 5pm. All depending on outside temps. 


The landing/kitchen reaches same temps as her room but has no heating there now. I've bought an oil filled radiator for landing which is next to kitchen so should heat there too to go on through the night for a few hours (since it is cheap electricity)  as I'm worried about the pipes freezing with the temps due to drop now. Otherwise I probably wouldn't bother as we don't hang out much in those areas so don't care too much for the cold there.

My bedroom has 3 outside walls, 2 windows

it dropped to 16.3 during the night, from 18 - no heating in this room the past 14 years ( outside temp 1oC )

No condensation, the room is massive and we dont shut the bedroom door and the trickle vents on the windows are always open

I wouldn't be worrying about frozen pipes when living in a flat. Winter of 2010 we had 3 weeks of nighttime temps of down to minus -16, no frozen pipes, other then the oil pipe from the tank to the boiler ( outside and above ground )  That was the only time Ive ever had heating on at night - two 20 mins blasts, to keep the oil flowing
