Does anyone have an opinion on the Worcester 30i condensing combi boiler?

All Worcester boilers are excellent. Make sure it's sized correctly that's all. If it's a 30kw then the house must be huge?

O.p. is looking for a combi model to replace the one in their apartment.

Didn't spot that!

That info wasn't in this post. It was in a different post on another "board".
Based on the comment about the size of the house - potentially the 30 could overdoing it for a two-bed apartment?
I've had a second quote with a recommendation for a Valliant ecotec 28 combi boiler.

Any thoughts?

The ecotec is a great boiler too

Thanks. This quote for the Valliant is considerably less than the first too.

Personally I would go for the Valliant 28kw ecotec, a very well built boiler.

But it is essential that the system is powerflushed and magnet fitted, cause if that particular boiler blocks up and overheats, then it can't be undone.

Hi, we got a new build house 7 years ago with a new ferrolli boiler.. nothing but probs all the time...finally got sick of spending good money after bad, and scrapped it to get a valliant boiler...has 5 year warranty and are meant to be one of the best going...a year later not one prob with it..very happy.
Also if you are on calor gas( prob u arent) but you get 300 off your bill when you upgrade a boiler, u just need proof of boiler purchase and fitting..

Thank you. Can you explain a bit more so I can talk to the fitter about this without sounding like the clueless idiot I am?!

Basically ask if the system is going to be powerflushed before the new boiler is fitted and a magnetic filter fitted afterwards.
Make sure he says yes to powerflushing, and not yes to a chemical Flush.
The difference is powerflushing uses a machine and takes several hours. It's the only way to ensure a clean system afterwards.
If he insists that a chemical flush will be good enough, then find another installer.
Whoever you get, make sure they use quality chemicals because they're are a lot of cheap crap on the market also. Good chemicals are fernox, adey, sentinel and kamco. Anything other than these are cheap crap. Same for the machine, fernox or kamco

Thanks so much for the info. Really appreciate it. I must check both quotes as I don't remember either mentioning doing this.

100%, as with any new boiler, but the pressure sensor on these boilers (same one as on the Glowworm) is particularly sensitive and can fail quickly on a dirty system.
But then any new boiler fitted to a dirty system is only asking for trouble and its the perfect get out for the manufacturer to void the warranty.

Worchester is the only boiler I fit. Best imo

If the sensor fails it can't be replaced isn't that right?

It can be replaced easily enough, its held in with a clip, did one recently.

I would also stipulate to home insurance provider when u up for renewal that you have new boiler and get it added onto insurance policy...they wont cover boilers unless stipulated..so if had probs or it blew in 3 years or so, they wont help..
Found all this out the hardway!!

I have a new worchester being fitted and all new pipes, rads, tanks, water tanks etc. Does this need a powerflush or is that only for old systems. Does it also need a magnetic filter. It's a 30KWCDi. Thanks and also don't mean to derail the thread.

Its always good practise to fit a mag filter and flush a brand new system to remove any bits of debris and flux etc.
The mag filter with good corrosion inhibitor chemicals will improve the longevity of the boiler and help to keep the system clean.

Thank you, would that initial flush for a new system be power or chemical?

There's something on those boilers though that if the heat exchanger blocks, and then overheats something blows and can't be replaced.

Would you mind telling me how much that is going to cost? We are moving into a house soon & plan on getting something similar done. Ours will be a 3 bed so your quote might not be relevant but might give us an idea before we get quotes ourselves

A powerflush will always be better

ive never heard of this , id be interested in hearing exactly what this issue is , to be honest i cant imagine Vaillant producing something like that , i hope they didnt

I haven't heard of that myself, although a blocked up heat exchanger is trouble enough in itself, I imagine if the system is that dirty there would be other issues to deal with like the pump and pressure sensor, muck in the divertor valve and plate to plate.

Ye I came across it a while back. I think the fault was f76( might be wrong). It was a blocked exchanger. I was sure it coujd be powerflushed clean but speaking to tech they told me that once this thermal fuse or something like that blows, it's all basically fecked. I wrote about it in the Rgi tech forum back in the day

I bumped it in the tech forum if you want to have a look

About 11K in total Inc VAT by SEAI RGI, full replumb of absolutely everything including all tanks attic and 400 litre solar (future proofing) pump, rads, boiler, new gas pipes for a meter move, kitchen, utility, 3 bathrooms. Heating to 4 bed with extension. In Dublin. All fitting included, sanitary provided by us.

As with most quotes get at least 3 and compare like for like, best of luck with it.
