Best rated Combi-boilers

[iddon]

Currently looking to replace our boiler and relocate it upstairs directly above where the current boiler sits, thus freeing some space in the kitchen. What in your opinions are the currently the best combi-boilers on the market for a 10 rad system? Let me know if you need further info'

 

[BigBurner]

Avoid the W-Bosch. They are 5 years out of date with poor control systems. The Viessmann with weather compensation is far superior.

Look at:
http://www.avantaplus.co.uk

Look at a the Dutch Broag Avantaplus 35C or 39C combi. Near 17 litres/min flowrate on the 39C. The 39C is £917 inc VAT, that is very well priced for a 40kW boiler. Cheaper elsewhere.

Look at the combi options pages 17 to 21. The outside senors etc, are extra.http://www.avantaplus.com/docs/Issue%205%20-Avanta%20Schematics%20Booklet.pdf

Have a Magnaclean on the return to the boiler. That will prevent any blocking up of the tubes in the heat exchanger. This applies to any boiler.

The Broag, has a 5 year guarantee. They use primarily industry standard components and little plastic with Honeywell brass hydrobocks. The Broags are better quality than Vaillant and much cheaper. They are well priced quality boilers having a superb control system with integrated outside weather compensation and OpenTherm protocol control. Buy the outside weather temperature sensor and use weather compensation - great comfort conditions and economy. You will not look back.

The best price/performance around.

It should be noted that BigBurner recommends the same thing to everyone regardless of their needs / budget / gas supply - whatever.

Yet again BB found his paste key.

OP's that are asking for boiler advice should avoid any input by BB.


He is a PC troll.

Trolling is a game about identity deception, albeit one that is played without the consent of most of the players. The troll attempts to pass as a legitimate participant, sharing the group's common interests and concerns; the newsgroups members, if they are cognizant of trolls and other identity deceptions, attempt to both distinguish real from trolling postings, and upon judging a poster a troll, make the offending poster leave the group. Their success at the former depends on how well they — and the troll — understand identity cues; their success at the latter depends on whether the troll's enjoyment is sufficiently diminished or outweighed by the costs imposed by the group.

Trolls can be costly in several ways. A troll can disrupt the discussion on a newsgroup, disseminate bad advice, and damage the feeling of trust in the newsgroup community. Furthermore, in a group that has become sensitized to trolling — where the rate of deception is high — many honestly naïve questions may be quickly rejected as trollings. This can be quite off-putting to the new user who upon venturing a first posting is immediately bombarded with angry accusations. Even if the accusation is unfounded, being branded a troll is quite damaging to one's online reputation.

Is he on commission

 

[clarkerothwell]

worcester bosch, Vaillant are known to be quite decent boilers, as are the top range Baxi's. I prefer Bosch and Vaillant myself.

OP

This is the reason to totally ignore the unqualified, incompetent and possibly dangerous BB.

He can't even make his mind up what is good or not and is reliably inconsistent

Also look at two high flow combis:
The W-Bosch Highflow 550.

. W-Bosch are old hat. They are 5 years out of date. I would not touch a W-B, until they get the control system sorted and updated.

That is great advice I gave. The Highflow although flawed on the control system has a v good DHW flowrate. If flowrate is the issue this is good and poor control system ca be stomached.

All the other models are out of date.

If you are moving the boiler into a bedroom be warned the noise may be intolarable.

Have a Magnaclean on the return to the boiler. That will prevent any blocking up of the tubes in the heat exchanger.

consider the W-Bosch. They have a good reliabity record and very good backup support. The Viessmann with weather compensation has got a history of reliability issues.

Look at:
http://www.vaillant.co.uk

Look at a the German Ecotec Plus 837. Its £1003 inc VAT, that is very well priced for a 37kW boiler. Cheaper elsewhere.

Outside sensors are extra!

The Vaillant can come with a 3 year guarantee, or even 5yrs from some installers. They use specifically designed parts by Vaillant in brass, meaning excellent quality. The Vaillants are better quality than Broag and competitively priced for a superior boiler. They are well priced quality boilers having a superb control system with integrated outside weather compensation. Buy the outside weather temperature sensor and use weather compensation - great comfort conditions and economy. You will not look back.

How to make an angry grandpa step 1

 

[Agile]

He is Big Burner on this forum but still posting as Water Systems on the screwfix forum.

He used to post as Water Systems on here too but was banned because he was encouraging unqualified gas work.

In his working life he used to be a design engineer for Nuway Burners and worked on large boilers hence his current posting name here.

He is now well retired and spends his time reading the manufacturers literature which he then regurgitates regardless of the relevance to the subject.

I am sure that in his day he was probably a good design engineer but that was some time ago and the world and particularly boiler design moves on!

Instead of spending time playing golf and gardening like most older retired people, he prefers to make these postings on forums. Unfortunately he has no practical experience as he has never been qualified to actually fit boilers or work on them so his postings are not seen as having much relevance by those who are at the sharp end fitting or repairing boilers every day!

Because he has no confidence in his postings, he keeps his identity hidden and we dont see him at exhibitions or meetings of the Institute unlike other retired people who still keep in touch and go to social gatherings!

hi - not an expert or a pro but... we recently installed an Alpha combi (18mths ago) and have had no problems - seems very efficient and was recommended by recommended plumber!
once called service centre for apparent pressure problem which turned out to be a burst main up the road... they were extremely helpful though - a comfort to know the response if there is a genuine need.
bought it with a jig which extended the guarantee to 5 yrs (and made it easier for the plumber to fit). also made a saving using an energy scheme - think it was 'magic boiler' although may have been another (through PTS? sorry can't recall) - worth checking options!
