Oil System Boiler Grant Or Worcester Bosch
Discussion
Hi all. I'm in the process of getting a new oil fired boiler to replace the 30 year old one that we inherited when we moved into the house last year.
Heating Engineer has suggested going for either a Grant or a Worcester Bosch one. No details of model numbers yet as his quote isn't in, he only came round today to look over the existing system.
So which make is best overall taking into account initial purchasing costs and their general reliability.
As an aside I was going to go down the Oil Combi route, but previous posts on here about their reliability put me off. Now going with a System boiler and pressurised tank. Anything that I should look for in the pressurised tank?
TIA

Had our Worcester Bosch 'Danesmoor' system oil replaced last year with a Grant system boiler. The WB had turned into Trigger's broom....and needed even more work/ replacement parts. Got a bit smelly, too (sited in our utility room). Lost patience with it so it had to go.
The Grant boilers are well regarded. Our heating engineer fitted one to his own house and since he's very experienced and always utterly straight with us we went for the Grant boiler too. It was a tad more expensive than the WB equivalent but so far we've been happy with the choice.
The WB lasted 18yrs (of admittedly pretty hard use up here in the Scottish Highlands), needed a fair number of new parts and let us down badly during a couple of winters. However, our heating engineer did say that getting WB spares was pretty easy and factory technical back up was very good.
I believe the Grant boilers have to be installed by a Grant 'approved' installer to qualify for a free extended warranty, or at least that was the case when ours was installed.
Well worth having a proper powerflush (not just a bottle or two of system cleaner) of your old heating circuit & rads prior to the new boiler going in.

Check these out. I had one of theirs installed last year and it has been spot on. Great service and advice.
Plumber said it seemed to be well built.
The company is owend by someone on here too I believe.

Grant byba country mile. We fit around 60 a year and maintain a further 1200ish and never have an issue with them. Worcester had an inherent design fault which means the baffles are prone to seizing in if not serviced within an inch of its life every 12 months. Once they seize in its only a matter of time before the boiler is junk. You literally couldn’t give me one for free.

As ^^^ Grant may not be the last word in hi-tech, but that's no bad thing 
If you have the room, I'd seriously consider a 'heat only' rather than a 'system' boiler. Generally easier to work on, and you're not paying over the odds for bespoke versions of regular ancillary parts. If your total system water content is large, you might end up needing an external expansion vessel anyway!

Both seem to be equally regarded by plumbers with 50% saying WB are crap and 50% saying Grant are the canines gonads (and simulateously slagging the other marque). Ultimately what they will 'push' comes down to the sort of trade terms your plumber gets on which model of boiler, but perhaps I being over cynical.
Our last oil fired Worcester Danesmoor combi went on for 20 years and gave good service before succumbing to a failed PCB which had by then become osbolete (or rather rendered obsolete by WB to force to you into a new boiler...damn I'm being cynical agian!).
We replaced it 3 years ago with a WB Greenstar condensing boiler and in fairness it's never missed a beat and the increased economy is noticeable. If you fit the filter they will also give you a 7 year parts and labour warantee which ultimately swung it for us.
PS: we've run oil fired combis in a big draughty old house for 23 years and they've been no less reliable than any other boiler.

They are recommended 50/50 mainly because they are the two big hitters in oil. Installers only will always push for the WB, guys who install and maintain will push for a Grant. The Grants are better made, easier to work on by a country mile and less prone to breakdowns. Grant also do not suffer the current issue WB have with baffles getting stuck and not being able to remove them. That alone can wreck the boiler in under 5 years. WB will turn around and say its not been serviced properly though Our last oil fired Worcester Danesmoor combi went on for 20 years and gave good service before succumbing to a failed PCB which had by then become osbolete (or rather rendered obsolete by WB to force to you into a new boiler...damn I'm being cynical agian!).

The old WB like the danesmoor were bullet proof and really built to last..ps, I have a new pcb on my van for your old danesmoor, they are still available. Ironically in the Gas world WB are regarded as one of the best, yet in oil they are rubbish. You couldn't give me one for free.
Firebird are up and coming, Hounsfield are getting good reviews from other engineers too, however personally I feel Grants have it sown up.

Both Grant and Worcester Bosch are excellent options for oil system boilers, recognized for their efficiency and dependability. Grant is particularly suited for those looking for energy-saving features, whereas Worcester Bosch stands out for its high-quality construction and strong service reputation.

That should help OP make up his mind.Love your novels by the way.

We've had a Grant external oil boiler put in this May.
Local G1 Grant trained installer came and did the final sign off, giving us a 10 yr guarantee.
Our plumbers said they didn't recommend anything else but a Grant now.
It replaced a Danesmoor Worcester Bosch that was installed in 1994 and was running pretty nicely! Assumed poor efficiency though, and it was in the wrong place.
I then sold the burner/pump/electrics for the 30yr old WB on eBay for £150.
