no hot water, central heating works fine

[fm1979]

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 a hot water tank ?

The chances are you have a problem somewhere between the programmer and the motorised valve, so yes the engineers choice of words are correct.
Depending on the type of work that engineer does its entirely possible they don't have the parts as van stock and would need to source them. That being said all the parts this fault could be are readily available at the local merchants.
A week without hot water is unacceptable though, have you not even used the immersion heater?
I would try and find someone else.

sorry that sounds gibberish to me: what is the immersion heater?
Sorry I'm very bad at plumbing, and my English is not better

You should have an immersion heater as back up for hot water in the event of a boiler fault. Take a picture of your cylinder please and if you do have an immersion heater one of us can point it out to you and tell you which switch to turn on.

Go to your hot water tank. If there is a cable going to it from a switch, turn the switch on …

Is that this?

You do have an immersion heater but it doesn't look like it's wired up .

How can you tell?

 

[SJB060685]

Because there's no cable going into it

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

Okay, the engineer that has done the diagnosis and who will come back is GSR.

It's not the white cable then?

There is a switch on the wall just beside the cylinder, it should be for the immersion heater then? (It's always off, I actually didn't know what is that switch for)
