no hot water, central heating works fine

[fm1979]

Hi, just wanted to give an update. I called another gas engineer who initially did a temporary fix to give us hot water, and 2 days later came to replace a diverter valve. Thanks for the forum's help.

Now another question: there is one shower in my home which is always a bit weird: sometimes, (even after the above problem was sorted) there is no hot water when I have a shower. So what I do is: I open the tap in the sink just beside it, and that seems to force the hot water to come from the shower. Looks like the other bathroom/shower is fine. Is it a shower problem?

I would say so

Hi,

I'm new to this forum, please apologies if this is not posted in the right section, or an answer exists already somewhere.

I have this issue: no hot water in any tap in the house, but the central heating works fine. The boiler is a Vaillant system 15.
A gas engineer had a diagnosis and said the boiler is okay and that it's could be a diverter valve issue. Or a thermostat.
We've been having no hot water for a week now and the engineer cannot come to fix it before end of next week.

• does the cause of the problem sound ok to you?
• is it really not possible for an engineer to come and repair faster than this? I understand he may be streched, but don't they allow spots for emergency appointments and repairs?

Thanks all for your time.

Do you have an unvented cylinder? Temperature setting? Has the overheat acted?....reset. Is the Valve opening?
