A combi can only heat one thing at a time, which is either the central heating or the water for the hot taps/shower. The hot water takes precedence, so as soon as a hot tap is turned on the heating is diverted away from the central heating in order to supply hot running water, and when the...

Although if you are unlucky, Vaillant may well hide behind the following clause on their website: Quote: As the installers listed on this website are not employed, contracted or approved by us, Vaillant cannot accept any responsibility for their workmanship. The terms of the Vaillant Group...

The Vaillant Guarantee: "7. The boiler must be serviced annually by a Vaillant or other registered Gas Safe Registered engineer in accordance with the manufacturer’s instructions." You should have a copy of the guarantee and the terms from Vaillant (our installer registered it for us, and...

Water softeners can be turned off if hard water is needed. We turn ours off whenever any work that involves adding water to the central heating is required. Boilers that have aluminium heat exchangers do NOT like water softeners, but we asked both Baxi (previous boiler) and Vaillant (previous...

There was a test carried out in Sweden which found that the only thing that actually removed limescale was a salt based water softener. We had one of those "wrap around" things in our last property - made no difference whatsoever. After the boiler got scaled up - again - we replaced it with a...

Yes, you can turn off the cold water at the stop tap and drain the taps and leave the combi on without problem. The central heating is a sealed system, not affected by using tap water. We always turn the water off when going away, and leave the heating thermostat on a low setting. With...

My understanding of combi boilers is that hot water takes precedence over heating. So if your shower is running directly from the combi, there will not be any heat going to the radiators while your shower is running.

Can you ask somebody else to come in your flat to see whether they can also smell it? It could be phantosmia - smelling something that is not actually there - and cigarette smoke and/or petrol fumes are two of the commonest. I had this for several years - nobody else could smell the cigarette...

As the opening post makes it clear that you were unhappy about items being removed without asking you by the 1st tradesman, why on earth did you not make it clear to the 2nd tradesman that there were items that you did NOT want removed? As a customer (not a trades) I have always assumed that...

A "smart" gas meter can't be fitted sithout a smart electric meter, as the gas meter sends readings via the electric one. As far as I can see, the thing that is most reported as having stopped working is the in-room display rather than the meter itself. As the in-room display is the bit that...

No. The smart meter replaces the current meter, type of boiler is immaterial.

Baxi website indicates that this code needs attention from a GSR, is not something that you can do yourself. Call out whoever services it - or call Baxi themselves.

If this is indeed a leisure/holiday static, hope that the caravan owner has permission from the site manager for all this - otherwise next job will be a return to remove it.

Not sure whether you mean a leisure static or a residential park home. If residential, they usually have "meter tails for shed" already under the home, so they can run underneath the home to the skirting and the external socket can be fixed to the skirting (assuming is the usual brick) so no...

As far as I know, there are quite a few different types of flush valves and settings. Did the plumber happen to have the valve with him or did he have to (a) look to see what type of cistern/valve it was, (b) find somewhere that had a suitable replacement in stock, (c) go and get the replacement...

My understanding is that it has always been the home owner who is responsible for making sure that the installation complies with regulations and is notified to building control. Suitably qualified electricians, gas installers etc etc have usually arranged confirmation and notification on behalf...

The installer may be correct in saying the manufacturer does the notification. We've just had a Vaillant installation by a Vaillant Advanced GSR, he notified Vaillant of the installation and Vaillant emailed us the Gas Safe Building regs certificate. The email includes the words: "This...

I'm a bit hesitant to say this - but I've read the initial post twice, and wonder if it is a case of not what was asked, but how it was asked? (Sorry - shouldn't butt in, I know).

As a customer, with no plumbing knowledge - if I thought there was a leak from a newly fitted valve I would have contacted the installer at the time. If I only told them several months later, when they were doing something else, I would say that I thought it had been leaking since xxx date - and...
