Is anyone else too hot at night with a combi boiler?

[PerkyOchrePeer]

How do people cope with sleeping at night in bed under a duvet with a combi boiler. I am too hot even though my thermostat has been turned right down a d it's so uncomfortable. I hate the boiler i did not ask for it because my housing association just gave it to me and I had no choice but IM unable to sleep because I'm too hot even with the temperature turned right the way down. I just can't cope with this anymore.

Don't have it on at night then.

This is such an odd thread. I have a combi. The min temp is set to 10 and we just turn it up to 21.5 to kick the heating on if we want it and then turn it back to 10 to turn it off again. Done it that way for 15 years.

Not a problem here. Ours is set to 18c and can come on between 7-8.45am and 5-7pm. It's not coming on in evening now as the house isn't dropping it's temperature so much. Heating wouldn't be on any later than 7pm unless is really cold outside.

You can just set your timer so it comes on first thing to take the chill off, does't even have to be set in the evening. Also, you can turn the temperature down on the themostat.

We had a combi boiler installed a couple of years ago and whilst it's very good for some things, I really regret doing it. My DH was persuaded by the heating engineer, but I miss the airing cupboard. We've had to have an electric towel rail fitted in the bathroom, but as we only have it on for a couple of hours in the morning, the towels don't get dry and warm as they did in the airing cupboard. Added to that the bathroom floor is now cold as there are no longer pipes going to the immersion tank. And yes, there is a normal radiator in there. DH was persuaded on grounds of costs, but I don't think we've saved anything at all, and, as I said, it's colder in the bathroom.

I know this doesn't help the Op, and I have no idea how she's so hot overnight if the heating is off, but I wanted to give my experience with a combi.

If your radiators are off and stone cold it is not your heating system making you hot.

Ok

Turn off your radiator?
Open a window?
Have a thinner duvet?
Are you menopausal?
Absolutely nothing to do with your combi boiler I suspect.

Where is the heat coming from if the radiator is stone cold?

Is your house comfortably temperate in the day?

If it’s warm then consider turning down the daytime temp but if your radiators are cold it isn’t your boiler making you hot at night.

Do you have something to set timings for the heating? An app or a manual control panel?

As everyone has said this is nothing to do with a combi boiler. If you have your settings so that the radiators aren't coming on at set times and they are cold now then you are either imagining it being really hot or you have the settings wrong so it is getting too hot to start with.

Mine is set to get up to 18 in the day and turned right down to 8 after 8pm so it doesn't get too hot. As well as that I have the individual thermostat on the bedroom radiator turned down so that room doesn't get much heat at all.

You are too hot for some other reason other than your combi boiler. As others have said there are many things you can do to keep cooler at night. Don't blame your poor boiler.

Do you have any family or friends who can have a look at the settings and timer for you to show you how it works

It must be Anthony...

There is a setting on your boiler where it will heat hot water only or heat hot water AND radiators. Turn it to hot water only.

Although I'm also confused how you are too hot but the radiators are cold. Maybe you need a thinner duvet/pj's now it's spring?

I discovered to my horror that when the batteries on the wireless thermostat that controls our heating go, the combi boiler just goes on automatic. Hence one day last June I returned to a flat that was hotter than the core of the sun.

May be that is the OP's problem?

Not if the radiators are stone cold, as the OP said they are.

On my combi boiler I can have it to do hot water only, or hot water and radiators?

I think this is a case of operator error rather than the boiler itself. Combi boilers are great and very easy to use.

I never knew that, thanks for the information!

Haven’t you got a timer? Just set it to come on in the morning and the late afternoon like most people. Your housing association should have left you instructions. I’ve had a combi boiler for 25 years without issue

A.combi boiler is no hotter than any other boiler! Most houses with a gas boiler have a combi boiler. Why don't you set it so it turns off at night time?

This is brilliant. So the OP has a combi boiler that somehow heats a room without using radiators? What a time to be alive.

Get your instruction book out you can turn the outdoor weather compensator off

basically it looks at the weather forecast and thinks it’s going to freeze tonight it’s going to be cold so it puts your heating on for you automatically overnight

turn this facility off it’s not shit it’s just you don’t know how it works and not bothered to find out

A combi boiler should only be coming on when either the hot tap is running or the heating is on. It doesn’t generate heat in itself.

Are you sure you mean combi boiler and not heat pump?

the boiler will switch itself on using the outdoor weather compensator which I explained above
