Heating of hot water requires CH to be on.

I have an Ideal combi boiler ( about 5 yrs old) and ever since it was serviced at the end of last year, have been experiencing the following:

In order to get heat water from the taps, I need to turn the CH ON and turn the CH temperature setting up. ( i.e. water temp setting has little or no affect).

I'm a bit stumped, but wondered if someone here has any ideas.
Some other possibly relevant info:

a) When the boiler was serviced, the heating was left full on when he finished. Without noticing, my wife went out shopping for a few hours, and returned to find the boiler bouncing off the wall. I only mention this in case something could have burned out.

b) There is an old mechanical (i.e. pegs) timer on the boiler. It seems capable of switching the heating on/off, but it keeps lousy time so cannot be relied upon ( some days it loses up to 4 hours, other days it's fine.)

Any advice would be very gratefully accepted.

Thanks,

SteveO.

That will probably be a £6 Diaphragm needed :D
Plus someone to fit it...what boiler is it :?:
 
HI Lagerkhan,

It's an Ideal C80FF boiler.

I'll have a look about at what the diaphragm does and how much to replace it.

Presumably, this is a job for a properly registered plumber and not just something I can do?

Its not illegal for you to do it PROVIDING you can do it safely without getting electrocuted !

Its not terribly difficult for me but I do sometimes encounter boiler installers who dont feel competent to do it themselves.
