red hot water from bathroom tap

[atm84]

Any thoughts to why almost boiling water is coming from the taps? Faulty stat on the hot water cylinder?

Come on use you trusted multimeter to test the stat is operating......and no dont use a voltstick.....

Has this problem just reared its ugly head recently or has the water always been too hot is the first question that needs to be answered.

From what they have told me its been like it for about 6 months. Ill test it with a multi meter the next time I'm round there.

Is this: Unvented Water Heater Faults any use???

Its a vented system.

Fair enough. Keep that link for when you get an unvented system to fix then!

Be prepared!

I hope it's sooner rather than later or this could possibly happen

If there's a tank full of mad hot water of course there'll be no immediate difference two minutes after you've turned the stat down

Your back

just read that article. that's awful. can't believe councils were aware but waiting till notification of problem from tennants. just wrong. that poor childs life, pain she went through and suffering the family still are, to delay spending 'small' money. totally wrong

Cheers guys. I've heard of some terrible incidents associated with unvented systems.

Thinking about it and from speaking with my relatives, I don't believe a stat is wired nor has it ever been. There is a stat connected to the electrical immersion element, however this is always switched OFF and the water is only heated when the time clock calls for it. Surely there must be a stat somewhere to prevent the water from boiling. Like I said in a previous post, this has only occurred in the last 6 months.

I think I'll have to go back and check it out.

Agreed - no delay in sorting this one OP

Had this on a fortic tank once - it boiled up and the water in the storage tank (at the top) eventually boiled then melted the plastic ball on ball valve - overflowed for about 2 hours (at night) - what an effing mess!

Nobody hurt though

Get a plumber in, sorted!

Jesus, for the price of an immersion heater stat, just chance the bloody thing, were talking of just a few £'s . Then if you're so inclined, you can open up the existing one to have a look at WHY it's not doing it's job.

Whilst I appreciate your comments Engineer, if you read my previous post I said that there is an immersion element with stat that is not connected. From what I have been told the water is being heated by the boiler when the time clock calls for it.

Should there be some sort of stat in the boiler which controls the hot water?

There should be a tank stat (calls for HW) and the boiler should have adjustable temp control
