central heating won't turn off

[matt66]

I have a ideal HE24 boiler. Problem is it turns central heating on its own and only way to stop it is to turn boiler off but when I turn it back on, it still puts heating on. Before I have turned boiler off for a few hours and when I have turned it back on, it fixed but now doesn't. Really worried its gonna cost a lot to fix. I don't have much money. Any help will be greatly appreciated.

Has the system got 2 port zone valves ?
If so check it not sticking open or micro switch sticking on.

Don't know anything about boilers so couldn't tell you. Would be in the
Manual?

Look in airing cupboard etc where hw cylinder is useally you see a pump just after the pump will be 1 or 2 valves in the pipework.

You need an gas safe engineer. Can't be diagnosed on the Internet.

Im stuffed then because there is no way i can afford for an engineer to come out.

Have a look in your local paper, there are usually firms around that do free estimates - it might not be as costly as you fear.

Had to replace mine about 2 years ago. My uncle has just had to replace his as well.

 

[acecharly]

Yes the replacements are orange the originals were black. The boiler is a croc of pants anyway. The new ones are alot better.

My uncle was the one who replaced it. He use to be corgi registered. Im hoping he might know what wrong with it.
