solving a cold bedroom

It is a corner bedroom. I might up the insulation in the loft. I will put the heating on but it's odd that all the other rooms are about 21 and this room feels about 16/17 degrees.

are those actual figures or just what it feels like ?

what it feels like and what is actually reading can be two different temps.

it would be worth getting an actual reading form the boy's rom and comparing with another one

I can't see the house being 21 if the heating is off (maybe if you get lots of sun). My house (well insulated) my thermostat is saying 18 that's with heat from us living there, we were away all last week and it was 15 when we got back.

No heating on here and am over 2.5 degrees up on you. Study is over 22 Maybe you are in Scotland

Is his room on the N side? My place faces mostly SE, so I get loads of solar gain in the rooms I use. However one bedroom faces NW so it never gets the sun and is cold. I had the same as a kid, my room was on the NE corner and freezing when the rest of the house was picking up heat from the sun.

Our lads room is the coldest in the house, it's a corner room with two exterior walls & faces North West. My study in beneath which is also colder than most of the house & isn't used much so his room gets little heat from it.

He has the option of a larger South East facing room but won't move.

^ This.

Your guesses could be way out. I'm in my home office in the upstairs East corner of our house. Two thermometers are telling it's 21C (no heating on) but I feel chilly and just put a sweatshirt on.

[Rangeroverover]

We used to dream of a room warmed up to 16 degrees, we had to get up an hour before we went to bed, lick the lake clean etc etc.............

[V8RX7]

If rooms are warm without heating then generally it's solar gain - IE South facing rooms are warmer than North facing

Which way does it face ?

Equally draughts can make rooms feel much colder than they are.

[wjwren]

N W facing.

The back of my house is south facing, even in October if its a sunny afternoon it makes a huge difference to the temp of the house, the only room on the North side is our master room and its 2 or 3 degrees colder than the rest of the house, nothing I can do about it. I have however recently had cavity wall insulation fitted, topped up loft insulation to a total of 300mm and its noticeable.

Probably a ghost in there or something.

Your sons bendroom is cold? Colder than what? The rest of the house or generally cold?

If it's generally cold, then put the heating on. It's been dropping cold overnight recently, so no surprise.

Why would you have not put the heating on yet? Our house has been cold for a month now really, so we have the heating on to warm it.

Why do you need to put the heating on already, it's not particularly cold yet. Put a jumper on !

[cylon]

let us know how you get on, I have same issue, heating is on in full whack and three of the rooms dont feel warm, compared to other rooms. When you walk in you can actually feel the cold air. This is a new build just built and moved into. (insulation above is ok)

I bought one of those laser thermometer and shows the walls in those rooms are 3-4 degrees less than others. Have logged the issue today with builder and i am 100% sure i will be fobbed off, so need to get some facts together.

[smn159]

Do you have solid walls? If so batten them out, fill the gaps with Celotex and plasterboard over the top. 50mm of insulation is ideal but even 25mm makes a huge difference.

Or just put the heating on

How did you get on with the thermal camera? What are the actual temperatures in the rooms?

Have you got thermostatic valves on your radiators? That would allow you to adjust the heat of the central heating room by room.

Updates with pics taken from the thermal camera required please!

I had a cold wall in my bedroom, leading to condensation where the air could not circulate etc., I put up thermal wallpaper - http://www.gowallpaper.co.uk/erfurt-mav-wallrock-k... - although not fully tested out yet, the room feels far warmer and I have not felt any condensation.

Be warned, it is not the easiest to put up! but it does cover a multitude of sins in un-even walls.

[wjwren]

didnt get round to doing it ive re-organised it for Wednesday now. Will upload pics and details asap!!

Quite often the radiator will be positioned near to the door (easier for the installer) where it is warmer than the far side of the room next to the external walls. If this is the case, the thermostat 'thinks' that the room is warm enough and shuts off the radiator before the far corner can heat up. Move the radiator (or fit a remote 'stat ) to the coldest part of the room.

before doing anything drastic/expensive, have you checked the radiators are actually balanced correctly? The rad in laddo's room might be on the end of the circuit so only getting lukewarm by the time the room where the thermostat is has reached switching point. We suffered this in our kitchen which was always freezing because the radiator never really warmed up. I then found one of the other rads was set on 'free flow' so hogged all the heat -I screwed the choke down on it and hey-presto the kitchen actually started warming up.

I used this on the bedroom at the top of the tower 3.5 external w alls, stone rubble construction 500mm. Best couple of hundred quid I've spent. Bugger to put up though.

I would agree with this: we extended over the garage a few years back - was always going to be a bit colder (no heating below!) but having a good engineer balancing things better has helped. Still not perfect, but definitely better!
Good luck!
