Is it just me who has the house heating on the same setting all the time. Except on days like this week where there is snow/frost on the ground, making the house feel colder, soooooo I turn up the thermostat...

Anyone else suffer from this problem? My brain says the house is the same temperature as before but still.....

I hate to admit it but yes, I heard its something to do with the humidity or air pressure?

I'll hand in my PH badge on the way out...

It may still say 20ºc on my 'stat, however, when it is really cold you can feel it coming off the windows and even walls, hence I turn it up a degree or two to override that chill.

In the summer my thermostat can read 18 deg C and the temperature feels fine.

But in winter, when it reads 18, the house IS cold.

I'm guessing that temperature readings are not an absolute indication of how warm or cold it is, and other factors come into play.

Also, at the moment the thermostat is set to 19.5 C and the house is easily warm enough, but as the OP says, when it starts snowing and gets icy, we also need to turn it up to 20 / 20.5.

Mines set at 18 and feels plenty warm enough, in this weather, i'd be more concerned on how crap your insulation is....

My insulation is ste, I have a layer of plasterboard in the loft rooms before the tiles. There is also some wattle and daub in places, but that is as good as it gets.

My walls hemorrhage heat too, hence why I have to crank it up.

I guess I should rip it all out and do it again, but how many years will it take me to get the money back on that?

It's not just you. According to the the temp gauge it says 20 but my legs and knees are like blocks of ice. Last week I had a coat on my lap to keep warm.

Likewise, therm says one, my body another & I don't normally feel the cold. Must be getting old frown

18 is 18 regardless of how much insulation you have..

Is it possible the room with the thermostat is warm and thermostat turns off, thus rest of the house is not getting heated.

You need to balance your radiators better. If you have a radiator turned on near to the thermostat, the heating will switch off when it (the thermostat) gets up to temp. Instead you should turn off the rad nearest to the thermostat and let the rooms you inhabit heat up until they bleed heat to wherever the thermostat is.

Yes I see what you mean - I wasn't very clear in my post.

I meant just the area (hallway) where the thermostat is cited.

I have balanced the radiators (they all have thermostatic valves) and when the heating is running, the temperatures are fairly consistent throughout the house. (within 0.5 to 1 deg)

In very cold weather the walls will radiate "cold" therefore you will feel cold even if the average air temperate in the room is fine. They will also cause cold currents of air fighting against the warm currents from the radiators.

I'm in a rented flat during the week and the thermostat is on the inside wall of the lounge, while the outside wall is all glass, with radiators at the base. Even though the radiators are on the colder side there is a definite temperature gradient across the lounge.

This is what I think. Also the double glazing appears to allow some colder air through so I get a little drafty... Certainly when you open the curtains you feel the breeze...

Glad it isn't just me..

Doesn't relative humidity have something to do with it? In our house it's about 30-40% but normally it's 50-60%

Maybe I'm wrong then; both the wife and daughter always want to put the heating up when it is colder outside and yet the thermostat is always set to 18-19, I tell them they are just imagining it, it is a thermostat and will regulate the temperature accordingly.

Probably doesn't help that I don't feel the cold.

The problem is - the thermostat controls to it's temperature, so although the thermostat may be at 20 degrees all year round - it doesn't follow that other parts of the house are.

Depending on what doors, windows are open - whether the sun is shining or not, how windy it is - certain parts of our house (especially at the extremities) can be significantly different in temperature to the thermostat which is located in the hallway.

The correct way to do it would be to have per room temperature monitors that control the radiators in each room independently and which communicate back to a central control unit.

I replaced my hall way stat with a Honeywell wireless one that sits on a stand so we can place it in any room. I put it in the bedroom at night which stops the heating coming on and off regularly due to it being bloody cold near to the front door where the wired one was located.

RH does affect your perception of temperature, however its pretty normal for RH to drop in cold weather.

Overnight the outside air drops below the dew point so water leaves the air. That air then naturally enters your house and gets heated so the RH drops. Its like a natural dehumidifier. The colder outside it is, the lower your house RH will be.

That said people dry clothes in doors during the winter so that can cause higher RH.
