never seen this fault, any ideas?

[southcoastboile]

Can't remember the correct name for them but the cyliners that have like a half cylinder on top that acts as a f+e tank, faucet mabee?

Anyway, customer said they were getting hot water out of all the cold taps in the house bar the kitchen one that is mains fed.

I checked the cyliner stat was set correctly and the 3port was switching on/off ok.

Does anyone have any other ideas what could be causinfg this? thanks

Elson tank??

[SafeGasInstall]

Mixer or cylinder is getting over heated !and pumps over and heats up the cold water in the up part of the cylinder

Someone turned on the old immersion heater by mistake and thermostat gone maybe

[glenno1]

The stat might be set but it may not be working(have you checked this)

[southcoastboile]

What would make it overheat though?

[southcoastboile]

My mate fitted a new stat, will check operation tomorrow, thats an idea. Any more? good replies so far, gives me a few things to look at

Cold supplies to bathrooms should not be fed from a combination tank as they will heat up and it sounds like this is what has been done.
Just swap it to mains cold through out the house.

Its a landlord that will definitly not pay out for something like that, aparantly it used to do it once or twice a year but now does it all the time, I left the boiler stst on 2.5 (old ideal wrs) not sure what it was on before. Thanks

Easy done at the tank. A fivers worth of fittings and should take no longer than 20 minutes.

Is it a fortic cylinder ??

[rawr]

combination cylinder, elson and fortic are just brand names, i think

[tamz]

Sounds as if it is
One of these type

Cold supplies should never be taken from one of these as the heat rises straight into the cistern.

Not much to stop the heat transfer in there!

yes all taps apart from cold in kitchen which is mains fed. Thanks Tamz, didn't think of changing it to mains next to the cylinder, kind of obvious now you've said it, ill recomend they do that.
