Central heating problem.

[Deancosmos]

Hello all. Hope someone can help, just recently I have no hot water unless the heating is switched on. I have made no adjustments, it has just happened. Once the heating has been on for about 5 minutes the water is piping hot again. Help??

Most probable cause is a faulty motorised valve in the airing cupboard. Assuming you have an indirect cylinder that is. You have not realy given us much to go on . ie.type of system and boiler installed.

Hi Gasman, sorry, I'm a bit of a dim bulb when it comes to heating and plumbing. We have no airing cupboard, I think it's a combi.

Sounds like you may need a new diagphram on the hot water flow switch.

Thanks gasman. Expensive ?

[gasman]

�65 i would be charging in my area.

[Deancosmos]

Thank you once more gasman. Not Epsom are you ?

[gasman]

Yorkshire i am afraid but a �450 call out charge should cover it what time do you want me there ??? :o)

[Deancosmos]

Probably cost me that anyway down here !
Thanks very much for your help.
