New boiler choice

Plastic hydroblocks in British boilers are problematic. Viessmann are better. Fit the shock arrestors, they are cheap.

Yes to the expansion vessels. Viessmann are less confident of their waterblock so they put an expansion vessel in the in the box of some models.

Look to longevity, some manufacturers have used the same composite without problems for 14 years, others have a different history. Not all are the same.

Bernard, the extra 4 yr guarantee is around £100. Intergas has few parts with the combi having only 4 moving as they say. They are very well built, like tanks. The back panel of the boiler is the heat exchanger. With a sockets set the boiler can be serviced in half an hour. Simple. Nothing like this design is on the market. The high flowrate Ferroli Modena, with only 4 moving parts, is good, but a conventional spiral tube-in-tube heat exchanger design, that has been used by many makers in the past. But the Ferroli stainless heat X looks well made.

Does anyone want to mention intergas engineers are (apparently) told to find reasons to invalidate their warranties over the slightest installation defects? Doesn't make them that attractive to me personally

They all do that. Nothing new. If they invalidate the guarantee, they had better have a good reason in writing, otherwise a few court cases will sharpen the makers up. Intergas boilers rarely break down. Not much to go wrong.

These threads always end up with the same people arguing.

Bernard you have offered nothing constructive.

Hard-work I think the point has been laboured. The intergas is very good, but the op really should find an installer and then go from their. Navien boilers I don't think will be in the UK market for much longer parts and boiler are hard to obtain, they are big in the rest of the world, but they've kinda entered the UK market somewhat half hearted. Ferroli new blue helix are very good, but it seems they spent a bit to many years happy selling below par products meaning every man and his dog has lost faith in the in the UK. It's very easy to tarnish a reputation but so much harder to make it good from bad. Most places have stopped stocking ferroli, and a few insurance companies have stopped supporting their boilers
 
All makers say it must be installed properly and the system cleaned. Got proof of cleaning? Filter fitted? Then they are on dodgy ground. If a maker does try it on, send them a letter explaining where they are wrong, and if they do not honour the guarantee threaten legal action. That sharpens them up.
 
Sounds like a long winded process to get your boiler fixed. While they're being 'sharpened up', do you live with a non functioning boiler in the hope that the decision goes your way?

I'd rather have a manufacturer who'll honour their warranty from the start. Doesn't call your integrity as an installer into question then either

Navien are not abandoning the UK. Parts and boilers are easy to come by.

The OP has a thermal store, when looking at previous posts. I would not trust the average plumber dealing with one. The first thing he will say is put an unvented cylinder in not understanding anything about thermal stores.

Ferroli do have bad rep over previous scrap metal they sold. But some current boilers are decent for sure. Baxi had bad rep (the boiler in question is a Baxi Barcelona which has appalling ignition equipment). And especially Ideal, who both have upped their acts. Look at the Ideal Minimiser!!! What garbage.

Once they know who you are and that you take no crap they will not try it on. If a boiler is poorly fitted all makers disown it. If they nit-pick, a fast strong letter, or email, will sharpen them up.
 
Always cover yourself. The Intergas boilers can be fitted as open vent or system (the pressure vessel must remain in place), the only combis that can be fitted as either. But nothing in the manual says that. Ring them, they say so. I sent them a nice email after a phone conversation, confirming what they said, with names and times. Then they cannot come back and say they disown it as it is not stated in the manual.

BTW, the boiler I mentioned, the Rapid, has been going for over 20 years. It is rock solid in reliability and longevity. It was first sold in the UK rebadged as an Atmos.

Presumably your "apparently" in that statement means that you're just parroting unfounded rumour?
