I've settled on an Intergas boiler.

Again I say "all received" and further grateful thanks. He has fitted Glowworm (he put a combi in my neighbour opposite's place). He tends to reckon WB are a tad overrated and not that simple to work on. But, as has been said, every installer has his favourites for whatever reason - be that cashback or freebies or just that they find one manufacturer to be better at backup or more reliable???



I hear your thoughts re IG and would just say that I do feel so confused when so many contributors have such conflicting experiences with ALL of the usual names - but the feedback I seem to see about IG seems pretty universally positive. BUT, comments on the forums don't tell the whole story, as we all know.

All food for thought though - and I remain grateful.

Were it me I’d get three quotes from different companies. See what they suggest and ask them why. I bet none of them suggest IG. Worcester are overrated because their boilers are not the quality build they once were and their service dept is now dire

 

[Stan]

Sound advice. ta.

I have posted a few times, mainly regarding my indecision to go for either an Ideal or an Intergas open vent boiler.

Having taken note of comments here and having, today, visited [with my installer] a local Plumbase shop to see the area Representative/Contracts Manager displaying an Xclusive combi boiler I (we) have pretty much decided to go for a 30kw Xclusive Combi. The bigger (36kw) is a bit too tall to fit the space).

Initially, and by way of a sort of compromise, I will probably have it fitted as an OPEN VENT boiler which fulfills my desire for retaining an unpressurised system and in keeping the F & E in place - and will upgrade to a full combi heating system at a later stage - i.e. if the hot water cylinder starts to leak or something else forces my hand.

The feeds to the boiler are currently from above and I'm told there isn't a stand off frame currently available and in order to run the pipes behind the boiler the rep. suggested standing the boiler off the wall using two lengths of 2" x 2" and a board made from something like 18mm ply. Both the rep. and the guy in technical confirm there's no need for a heat resistant backboard.

I have a 22mm gas supply to the boiler. I'll fit a Magnaclean Pro 2 and will have the system flushed. I'll change the present manual bypass (in the cylinder cupboard) for an automatic one. I have already run a 3 plus earth cable from the cylinder to the boiler.

What, I wonder, have I missed?

Thanks to all who advised previously and led me towards the Intergas option.

Just in case you have missed this, the CH output of the Xclusive 30 is (100%) factory adjusted to 19.4 kw output, probably no big deal except that you are heating large amounts of hot water at the same time.

Kind of irrelevant though if he’s contrmplating changing his mind

Seems a daft idea to fit a boiler which is really a combi then decide to use it as an Open Vent boiler (Another gripe of mine about Intergas but that's another thread).

Decide what you want exactly rather than trying to compromise. If you want a combi, do the full conversion now. If you want to keep your cylinder have a system boiler and make it a sealed system.

I convert all systems to sealed, regardless. My view is that if your Open Vent system is prone to leakage, leaking somewhere or other issues, you may as well address them sooner rather than later. One, a leaky system will knacker any new boiler in due to the introduction of fresh water into the system, secondly if a pipe goes the F&E tank will just keep filling. Least on a sealed system it'll only loose the water in the system and cause less damage.

Did a combi conversion last year and theirs was OV. On making it sealed it was evident there was a leak. Turned out the pipes had corroded under the wooden suspended floors downstairs, had been leaking for years and made a right mess under there. If we'd just put an OV back in we wouldn't have been any the wiser.

You just need to unplug the sensor to make it open vent . Kop

 

[Stan]

Yes, I accept my line of thinking is flawed.

I have no evidence of any leaks in the drops which are behind the plaster board of the downstairs walls but accept I wouldn't be aware due to the open vent currently in place and that a system boiler would tell me if there was.

Everyone's contributions are getting me thinking (a lot).

 

[Stan]

Re. Unplugging the sensor- yes indeed you reminded me the rep. said that today. He said an awful lot and it's true to say I can't recall every word.

It would be a bit surprising if this is intergas approved.
