Central heating help needed, any experts about?

[Graphista]

My flat is too warm, I thought thermostat wasn't working have replaced batteries. It says temp of flat 4°c higher than where I have thermostat set at and heating is still on, I don't know if I should turn off at boiler I don't want an unnecessarily high bill! I've worked hard to get direct debit down.

Can anyone help please? I'm in a flat on 2nd floor so flat below and above so well insulated.

Don't wanna cause pipe issues either though and advice is 15°c is lowest temp you should have at but then if flat supposedly at 19°c am I ok to turn heating off?

As I said REALLY don't want to incur a high bill!

What happens if you set the thermostat lower?

What have you set the thermostat to? The heating should turn off when that temperature is achieved. The weather is currently much too warm for frozen pipes to be a consideration.

If I set it MUCH lower eventually heating goes off but I'm worried about keeping everything running well

Thanks for reassurance re frozen pipes I am in Scotland though

Although yea outdoor temp apparently 6°c

Even in Scotland your pipes aren't going to freeze a little below 15 degrees (which is practically summer in the Highlands!).

Do you have a thermometer?

Do you understand how a wall thermostat works? If you set it to 18°C, it will tell the boiler to run until the temperature in the immediate vicinity of the thermostat reaches 18°C, then it will tell the boiler to stop. Now, the radiators will still be hot, so the location of the thermostat, and the other rooms, might continue to heat up a little. However, if the property ends up much warmer than what the thermostat is set to, it may be faulty.

Is the thermostat fixed to the wall or is a digital one you can move around? You might find it better to put a moveable one in a different place as it may be taking the reading from a colder part of the flat. Do try turning the temperature down a couple of degrees to see if that makes a difference.

Is it gas or electricity?
Just turn the thermostat down until the flat is at the temperature you want

It's supposed to be wall mounted but the wall mounting is broken so it sits on the hall table.

Yea I know it's SUPPOSED to do the heating as when the temp drops below thermostat setting heating kicks in.

What's happening is when I turn thermostat down the heating goes off but as soon as I stop touching the thermostat the heating comes on again

Gas

No thermometer just check the thermostat maybe need to get a thermometer

I've just turned the heating off manually at the boiler and I'm not even sure that's working!

Do you have a hot water cylinder or is it a combi boiler? We had a faulty diverter valve and my heating was going on full blast when it was supposed to be off. Maybe needs someone out to look at it

Combi boiler

Yea I think it does but I rent and it's almost Xmas so popping it on/off at boiler for now and will chase with landlord in new year. Annoying timing! Thanks everyone
