[travu2yell]

I have a Valiant boiler and have a timer control (for heating & hot water) in the airing cupboard and even though i have turned the water timer off completely the water is still boiling hot please help !!

When did you turn the hot water off at the timer?

How long ago?

Hi,
I turned it off yesterday and the bath has been used twice to try and use the hot water - but it wont go away !!!
Many Thanks

With the hot water turned off at the timer, is the boiler still firing?

 

[travu2yell]

Has the immersion heater been turned on?It is the thing with the wire stiking out of the cylinder.

ok the boiler is still firing - do you have a 2 port motorised valve (s). USually silver cased, on the pipes near the cylinder.

Hi,
No the immersion heater switch is below the control panel and is definately off

Could it be the diverter Valve on top of the water cylinder ?

Hi,
There is a three way valve I think, like a T junction.
Thank you
