Choices: Worcester-B CDi or Si or other compact combi?

[les24preludes]

I need a new combi boiler for a modest 2 bed flat, 1 bathroom. Priority is good build quality, reliability and after sales service. What's better between the Worcester-Bosch CDi and Si models? Or should I consider another make? Opinions very valuable at this point - need to decide! Thanks.

TBH there both the same, I prefer the cdi range myself

 

[Harvest Fields]

I prefer Vaillant

I prefer Vaillant

Vaillant is another option. Can you give some reasons why you would prefer Vaillant?

 

[Harvest Fields]

Each engineer has a different favourite. Mine is because I have fitted many Vaillant’s. Only had a problem with 2 and Vaillant came and fixed them promptly. But someone will be probably be along shortly to say the complete opposite.

The Ecofit Pure is the compact version - is this any good? The Ecotec Pro is bigger - any advantage there?

 

[Harvest Fields]

pure should do what you want it to.

Baxi 600 compact and decent value .

7 years and repaired within 24 hrs on works scheme

Viessmann every time

I haven't looked at Baxi yet. Viessmann has some good feedback, but I'd prefer a common model with easy to get parts. I've been reading more reviews of Worcester Bosch and Vaillant. Fitters seem to prefer the Vaillant - easy to fit and repair and good quality parts is the general comment. W-B has the best guarantee and service feedback. Some fitters say it's easy to fit, others say it's frustrating with some sharp parts in it. W-B is cheaper to buy and repair in terms of parts, but Vaillant is a very common make and should be easy to service. W-B is more compact and takes less space, but maybe at the expense of being harder to work on? In terms of Valiant I have no real feedback on the EcoFit Pure - that's a bit of a mystery. Between the Pro and Plus models it's not clear - there are fans of both. I believe they both have stainless steel parts which is an advantage over aluminium.

More views welcome....

I would defo agree with going for a common model .
Been their before going more off spec never a good thing.

Fitted a few Vaillant Pure now, Good Boiler, Neat, compact, does what it says on the tin

If you want a well known brand go for the cdi , avoid the baxi 600 they are having issues as with all new model boilers , i am recommending Atag top end 10 year warranty and intergas 6years warranty for middle of the road. Kop

 

[hammers4spanner]

Well if you go with the cdi make sure you have every part listed kept n the garage as they fall apart for fun.
Loads of them round here reckon life span no more than 8 to 10 years.

Issues with the 600 ?

How its a scaled down duo-tec which has been around for years all brass inside and now centred flue.

They have had some issues with eco-blue.

Most issues down this way with baxi's are blocked plates due to bad installs.

Issues with worcester's start the second the box is opened!!!

Atm it's quality control issues

And have to disagree with you about the cdi series

What's breaking down on them ?

 

[Harvest Fields]

I disagree with both of you Ohh and Vaillant’s are the best!!

 

[jtsplumbing]

Depends what you want to spend loads of boilers available on the market other than WB & Vaillant , and with long warranty's up to 12 years , at the end of the day they all get problems regardless of what you fit

 

[king of pipes]

As with alot of new model boilers it takes a while to iron out niggling faults , the Ideal Vogue is another possiblity and has a 10year warranty, as you can tell ask 10 boiler installers which boiler they would recommend you will receive at least half a dozen different answers , talk to your installer and get his advice and experience. Good luck kop

 

[hammers4spanner]

Its just not boilers cars,phones,tv's built to fail so you keep renewing.

in order of prefference vaillant viessmann glow worm

Much as I like the idea of a compact combi in my kitchen, it's looking like you need enough space inside the casing to properly lay out all the parts in a way that they can be easily installed and serviced. So I've eliminated the W-B Cdi and Si in the light of a number of comments on their build and installation. This leaves a lot of quality makes like Veissmann, Atag and so on. But in view of easy parts availability I'm still thinking W-B and Vaillant. For W-B it would be the 30i and for Vaillant the Pro or Plus. Not sure between these three, but at least it should be a step up from the compacts. That's my current thinking, if anyone would like to comment on that.

 

[hammers4spanner]

I currently have the 30i in my own home and it' pretty loud the pump drones like hell.

"I currently have the 30i in my own home and it' pretty loud the pump drones like hell".

How old is this model? I believe it's been revised recently?

 

[hammers4spanner]

We have been in our current home for 6 months and was installed just before we moved in.
Personally far from impressed
