Valiant and Worcester Boiler Quotes

Yes, the way to use Which? is to read the words, not just the ratings, they sometimes think something is unimportant when for you it would be critical. They once recommended a Black & Decker drill even though it failed before the end of their tests! Your post also highlights another longstanding problem with Which?, it puts Vaillant above Glowworm yet they are the same company. Years ago they had a Hotpoint washing machine as best buy & a Creda as a "must avoid", they were the same machine with different badges!

Ok but the engineer who fixes them for a living said he rated Vaillant best. He did not say Vaillant and Glow-worm.

Plus being "owned" is not really the same is it?

Glow-worm are sort of like Vaillant Group’s budget boiler.

Very very rough guide, 1.5kw per rad and 3kw for hot water. So you need 19.5kw without your underfloor.

Hopefully someone will correct me because I’m not sure with underfloor, I’ve never fitted it but I’m think they say 100w per m. Now if that’s correct you need to allow 4.5kw for the underfloor, making a very rough total requirement 24kw.

There is a lot that goes into heat loss calculations and they need to measure your requirements accurately but if the 24kw is correct then ignore the cdi 42kw, it will hugely oversized.

Are they converting to a sealed system for the quote 3? do you have radiator pipes under concrete floors? if you haven’t I would get them to price the Vaillant as a sealed system, the Vaillant 630 is made for a sealed system. If you have pipe work in concrete floors I would leave as a open system and ignore quote 3.

Do you want to re-read that?
I'm not home now so can't check, but, IIRC, in the ratings column there was a line for reliability and Worcester says ***** whereas Vailant says ***

Doesn't it??

Happy to..........

WB 92%
Viessmann 84%
Vaillant 78%

Yes the reliability is 3 and 5. But no one is judging the product on JUST that. We are talking about a product as a whole. Very few people buy a product on reliability and nothing else.

Did you miss the 5 star for customer score
5 star for ease of service.
5 star for ease of fixing
5 star for build quality
5 star for fixing a common fault
4 recommendation
4 availability of parts and spares..........all for Vaillant????

So which is not really saying they are 3 star are they. If you are implying they are a poor brand then thats not reflected in the whole Which report?

And in support they are rated on many other sites and by most engineers.

J B I’m not going to dispute your problems with your Vaillant but I can honestly say Ive only fitted a handful of PCB’s on Vaillants in 15 years. I have 1 in my van as stock and it has got 2014 printed on it which means I haven’t fitted 1 since then. I have 4 Worcester PCB’s in my van. The thing is your now put off by Vaillant because of your bad experience which is understandable but it’s unusual.

Worcester are a £300 boiler that costs £1000 & they use the £700 to market them
The only thing which boiler recommendations are any good for is wrapping up your fish & chips
