Manufacturer in the country? Or is just my perception that their boilers are crap and their backup, technical and overall setup absolutely appalling

Blocked DHW heat exchanger. Wouldn't have thought a DIY job, new heat exchanger £115 or theres a place up North ( forget exactly where, I've got the brochure in the house somewhere) where I've had two from now £29 + £15 delivery.

We've already had loads of these go. When questioned about the use of rubber hoses Vaillant told us that it was to help with expansion and that it was only a small problem. As soon as we saw the first ones we knew that this would be a recurring problem.

How outrageous.... a pump that has only lasted 20 years. Buy a new one you cheapskate!

I've never really understood why people quote rules and regulations as regards distances between clipping pipe. If you think a pipe needs a clip at a certain point in the run to make it secure clip it!! If that means 4 clips inside a 1 metre run then so be it..if it needs less then...

Leave it as it is. If the customer wishes to do major alterations let them. The sooner that open flued appliances are banned the better anyway in my view.

We've had similar problems with these boilers. I had problems with one, changed absolutely everything and just sat there scratching my head, no explanation whatsoever as to why it wouldn't work. Baxi couldn't offer any idea as to why it wouldn't work, I finally consulted with one of my...

We had a lot of problems with the 30CXis when they came out on hot water only, the burner would literally come on and off very rapidly in conjunction with a whooshing noise as the burner came back on and then shut down in short order. The water of course would keep running cold. Although...

The engineer was obliged to point out the inadequate air vent and did just what he was required to do under the regs. Those terracotta vents normally taper down to next to nothing on the unexposed side and are virtually guaranteed not to be sleeved. As it stands any vent which...

It`s not mounted adequately. I can`t advise about the smell but I am currently fitting these without any probs.These are pretty heavy bi*tches. Big problems with the fans on these boilers, we carry out a major council maintenance contract and were alerted by one of the other council...

Water expands when it's hot which is why the pressure is greater when the boiler is on. Personally I pressure up the system to about 1 and a quarter bar (always do this when the system is cold to get an accurate reading) the pressure will then obviously increase temporarily when the...

Don't forget that if your BBU and fire were originally correctly fitted to the decorative brickwork and you remove it, you will have to reposition the whole installation as in moving the whole BBU back so that the new front face of the chimney breast is between the notched Vs on the boiler...

Yes you can let out a little pressure out of the drain valve on your pipework or rad. If you let out too much just top back up. I wouldn't have thought that it is due to a cracked DHW exchanger or passing filling loop valve if it only happens every three years ( although I do agree...

My company fits hundreds of G/worms and they are rubbish, we do so many that we do our own warranty work on them. G/worm as a company have never actually mastered the art of designing a PCB that lasts longer than about quarter of an hour. We have fitted a handful of Flexicoms in restricted...

I know that this seems a touch simplistic but I had a call yesterday to one of these boilers with exactly the same fault description given over the phone (without the resistance stuff) And was due to no pressure in the system, CH worked a treat but lukewarm HW, repressurised and away she...

Yes You can turn the valves on one at a time if there are two, you will hear the water going into the system, take it easy and then just turn the valves off one at a time (just the one initially will stop the water you will hear it stop) Pressurise up to about 1 and a quarter bar...

To be honest I did consider that the enquirer was talking about a mantle ( which allowing for clearances is obviously fine in wood) rather than a surround. However the mention of a crappy flimsy bit of B&Q laminate being incorporated into said MDF construction caused me to gaze into my...

You're quite right lots of fire surrounds are made from MDF, theres also lots made from hardboard, and theres lots made from solid wood. And I spend all day every day turning off and isolating the appliances fitted to them. But as you know better carry on.

MDF surround?? STOP and call in a professional!!!!!

One reason for symptons similar to yours that we have encountered on a number of occasions causing loud rumbling vibrations so loud that they annoy the neighbours also, is due to insufficient gas supply at gas valve inlet caused either by meter governor packing up or undersized gas pipe...
