blown combi boiler

[greendiff]

A week ago, i put the heating on to take the chill off, and the boiler promptly blew up.

Ive been away all week, so am now only just getting around to getting things sorted.

Its a Viesmann Vitodens 100-W, an internal hose burst, which was the original failure, which then fried the control panel.

I have no records for the boiler, but i suspect its from around 2015.

At this point, a replacement may be the better option to go for rather than repair, and finding more things wrong.

What does a boiler cost these days?

11 rads, 1 bath.

[sherman]

3k if it a like for like replacement in the same spot.

[OutInTheShed]

I think you are right, mending it will be expensive and probably short term.
Get a new one, with a decent warranty and write it off over 7 or even 10 years of the warranty.

[greendiff]

Seems my thinking was along the right lines.

What brand? Are there some to avoid or are they all much the same these days?

Worcester-Bosch
Vaillant

END of list ....

Unless you actually mean blew up as in an explosion in your house ?
Why not first get someone competent to diagnose the fault . Its not that old .

'Hose burst and got the controller wet and killed it' seems a fairly simple thing to diagnose.

Sounds like a replacement hose and then a controller from eBay.

Seconded.

Not had mine for very long, but very quiet, efficient and stainless steel heat exchanger. All good

If you don’t fancy trying to fix it yourself you could get a fixed price repair from Viessmann or even British Gas.

Not everyone loves Viessmann but they’re supposed to last well with stainless steel heat exchangers and they have better modulation ratio than most other boilers which would suit a smaller heating system.

Best bang for buck is a Baxi, cheap, reliable, 7 or 10 year warranty. My mate runs a plumbing shop and sells 1000’s of them, probably 90% of his sales are Baxi. I had a Baxi in my last house for 15 years, it didn’t have a single fault in that time, I’ve just fitted one in my new house and have probably fitted 40 of them in my flips over the years.

The problem is, repairs quickly cost a lot of money and th rest of the boiler is still old..

Getting a plumber in to replace random stuff often works out dear, then something else fails next year. Or next month.

If you fix it yourself, it's more worthwhile, sometimes the only thing wrong might be one easily identified part, sometimes loads of parts are 'not quite perfect', so it will never run quite right, which may be putting more stress on things.

Fixed price repairs are worth looking into though.

It's a tough line to draw sometimes.

Might be worth considering British Gas Homecare as they cover pre existing issues or used to then you also have 12 further months of cover.

Baxi may be popular (cheap), but compared to a Viessmann... it's like deciding between a Fiat 500 and a Tesla.

Fix your boiler, you'll get another 10 years out of it for a few hundred quid.

Viessmann are the biggest piles of st ever built a truly awful boiler to own and work on. Dont get why there is any love for them at all. Up there in the quality stakes with ariston biasi and ferroli. Rip it out snd put a vaillant in.

As usual with PH boiler threads, you’ll get a recommendation for every boiler brand and also advice to avoid every boiler brand like the plague

Looks like the parts wouldn't be that much, used control board appears to be about £100, hose part wont be much.

For that money you may as well fix it, even if only does another 2 or 3 years better than than spending £3k on a new boiler. It might work happily for another decade.

I was waiting for this and also the anecdotal 'my friend the plumber says' comments.

It's the same with"which is the best vacuum cleaner" threads.
