Even Drivel didn't say you'd get a 40% saving on gas - he said *up to* 40% - which is a bit different - and grossly optimistic at that unless you've got a literally 'stone age' boiler. As long as the 'iron lump' can be restored to reliable operation, stick with it - by the time a new boiler has paid for itself in fuel savings, *that* will need replacing.
Simple question, it was. Response completely as expected ;-) You are a masterpiece...

Write like an idiot, insult and idiot, then you get treated like an idiot. Haven't you figured that out yet?
Nope. 33% is the least you should expect.
You are totally mad. You don't know much about this game do you?
3 to 5 years?
The OP's description was "a fifteen year old rarely serviced (probably never since new)" boiler so the new boiler may well save 40% on the present gas usage. But servicing the existing boiler might produce a double-digit saving.
What a totally pointless response.
Note it's now changed to 'up to 40%'
Drivel gets all his figures from adverts. Think of him as a double glazing salesman and you won't be far out.
Got any mirrors in your flat?
And this simply gives proof that you're not a pro, but simply a reader of adverts.
If you gave this in writing, you'd be out of business.
Well, the boiler is unlikely to use that much gas when sooted up - if you continue to try and use it - and it does fire up - it will probably explode. ;-)
However, until that point I doubt the efficiency changed at all during the many years where it was working properly.
OK, fine, whatever....

I know enough to know that your 3-5 year payback period is totally false.
A realistic fuel saving is nearer 20% - say £80 p.a. on a £400 bill. That will give a payback period of *at least* 10 years - and even that ignores the increased servicing costs of complex condensing boilers.
I will leave it to other contributors to judge which of us is the madder!
I have a 24 year old boiler that's >84% efficient so it would take ages to get the costs of a new one back. There is not a lot to service either, just vac it out occasionally and check the flame is burning OK.
Were other boilers of that era significantly different?
PS. Can I move it to a new location if I build an extension or do I have to fit a new condensing boiler? Its only 50,000 btu so I might just keep it as a water heater (storage) and run the heating off a new one (in the attic?).
It is clear you know this from experience. Took down a few houses in the street.
10/10. Very good. Did someone tell you that at the home?
Did someone tell you to laugh?
Greater than 84% efficient and 24 years old? Make and model please? More like 55% if that.
Stop making things up. Also you would be saving the planet.
