no hot water, central heating works fine

[Deleted member 120897]

I however booked my guy for next Friday, is that bad if I cancel him if I find someone else?

No, if he’s not G3 registered he’ll understand and be grateful you haven’t wasted his time, and you could avoid an unnecessary Callout charge. Just because he’s gas safe registered, doesn’t mean he’s G3 registered.

If you politely explain to the guy you have already booked for next Friday that by then you would have been without hot water for around two weeks and is it possible if they could attend sooner. If they say no then inform them you will see if you can get someone sooner. He/she may not like this but as I said before it is completely unacceptable to be left without hot water for that long. I can tell you now that if you were a customer of mine, under the circumstances you would have been treated as an urgent call.
You can go on the Gas Safe website and search for technicians in your area that hold both gas and G3 qualifications.

Many thanks, will do. Awkward conversation in perspective...He was not shy to come for the diagnosis the same late evening and charge me 70£ and no clear cut diagnosis. Anyway....it's done it's done.
I've been to my local gym club to shower, I'm fortunate to still be a member, I actually wanted to cancel haha.

You've been super helpful.

Thanks, another thing I didn't know! I learnt so much tonight.

It also appears you have an unvented cylinder, so make sure your engineer attending is G3 registered.

sorry, one more question, how can you tell it's an unvented cylinder?

Because if it was an open vented hot water cylinder it would usually be a copper foam lagged cylinder.

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?
