    Which combi boiler brands are best? 7th Jun 18 at 2:02 PM
    which combi boiler makes and model does everyone here recommend and which are reliable please?

    I have had quotes and prices from various plumbers for the following boiler brands:

    Worcester
    Vaillant
    Viessmann
    Ideal
    Gloworm
    Main
    Biasi

    (I know Biasi isn't a good boiler)

    which do you guys think is best or worst and which do you have in your house? All of the above boilers come with a guarantee but only one comes with 10 years. Also, Atag who i never heard of got mentioned.

    i also had a rather crazy quote from British gas for more than 7300 which i will post up, I know its a rip-off but want to know whether the work is required, or not!

    I think this thread helps to answer some of your questions:

    https://forums.moneysavingexpert.com/showthread.php?t=5631484

    Atag - you might struggle to find installers unless you already have a good one lined up. Great boilers though, just not popular with the customers yet.

    Avoid Biasi.

    7300 looks expensive, even if all of the following is true:

    • you live in a 5 bedroom house
    • you have 3 bathrooms
    • you're having underfloor heating installed
    • you're having new radiators installed
    • you're having a top boiler installed
    • all your pipework is being renewed and buried underground

    British Gas, along with most other larger companies, sub-contract a lot of their work out to companies like the one I used to own - a small company employing less than 10 guys. We did the work for BG and got paid a little more than half I expect.

    There's plenty of local installers to you that will give you a great installation for much lower costs, even if you're in London.

    Edit, if you or others don't mind boilers you might not have heard of then, Intergas would be the one for me - level with Vaillant for overall best value. (Just my opinion).

    Im really happy with my combi Valiant. It was around half the price that BG quoted me (and tried the hard selling tactics...like a managers discount if `i signed up on the day of the survey!!)

    Valiant service mine annually too, and are extremely thorough.

    Intergas,would be my first choice.

    Most boiler manufacturers internet home page have a 'find a local installer search facility'

    Something I've looked into and these have always been consistently favorably mentioned: Worcester Bosch, Valiant, Baxi and Potterton. Am not saying others are not good just that these have consistently been mentioned as being among the best

    Would it be straightforward to find installers for the above mentioned as they sound good

    Intergas
    Atag
    Viessman

    I do however like them, they're not bad boilers and a lot easier to sell.


    I do however favour Intergas, they do things different inside which does away with the diverter valve.


    It's a hard sell though because no one here has heard of them, and usually it's Worcester Bosch that end up in the house.

    Agree. Parts were hard to get before and the sales reps were also hard to get hold of. They were just too small before but it's much better now.

    Engineers love them because they have very few moving parts and are extremely easy to service and repair.

    Not sure about the Baxi boilers except possibly the Ecoblue. Potterton is also a no no no for me.

    Agreen with Southcoastrgi's list and would also add Vaillant into that mix if they don't go down the cheap route too much.

    Potterton are also a no no with me for the way they dealt with the faulty Suprima pcb issue. Brief summary - Suprima pcbs failed in huge numbers due to bad design by Potterton. Potterton briefly fixed them in the boiler equivalent of a recall about 15 years ago, but won't offer anything now to acknowledge or fix the problem. This problem is still occurring today to those who haven't replaced the pcb. Boiler perfectly good otherwise.

    Get the one with the longest warranty, my plumber claimed that Worcesters last longer than most he has seen.
    Enjoy everyday like it's your last!

    There's a lot of boilers on the market that now come with 7+ years warranty. It also helps if the engineer is a accredited installer as they sometimes get extra years on top.

    Some manufacturers have increased their warranties but made their boilers more expensive, just to keep up with the others.

    Remember, if you don't service your boiler annually it voids the warranty. That's an added cost that some would otherwise not have accounted for.
