    Morning all

    I am about to change my old system set up to a combi boiler. I live in a 3 bedroom semi currently.

    Now....I am a joiner and in the building trade so have a few trusted heating engineers I have asked for advice and opinions....all of which are different!

    some advice is to go with a vokera easi-heat or vision for the warranty, some say the greenstar 25i.

    I would really appreciate your input

    Do you have just 1 bathroom? Or an ensuite? Depends on the size of you 3 bed? Small or large. I personally wouldn't fit anything less then 28kw dependant on the size of your house. Stay away from vokera in my opinion. It I am more of a vaillant man.

    We all have our own favourite boilers. It depends on the GSR who is going to install it and look after/service it for you and your budget of course. Personally I would go for the Greenstar but others would disagree. I would not fit any Vokera TBH.

    thanks for your advice guys. just one bathroom and its a small 3 bed.

    the guy I have got to fit the boiler is really non committal about what I should use...one minute he says the easy-heat is a bargain the next he would go for the greenstar!

    The Vokera may well be a bargain, but in my opinion Vokera are nothing but trouble and not very reliable with a terrible customer after sales service. I would also agree with Harvest Field that you should get at least a 28kW boiler. They all modulate the heating so that does not really matter it is the hot water where it counts the more Kw = more lpm and better performance.

    Maybe the flow rate and gas pipe dictate a 25kw boiler

    Get the best you can afford but more important is that it's fitted correctly and flushed well
    Make sure you get a magnetic filter
    Good inhibitor
    Lime fighter if needed
    Shock arrester

    I'm a Worcester man myself there warrenty if anything should go wrong is top notch

    And agree with the above depending on gas pipe supply I would 28-32kw depending on your mains flow rate

    well thanks for all the input gents. having read your comments and looked into the 25I and 30i greenstar boilers it actually works out cheaper for me to get the 30i as the deal includes a flu whereas I would need to buy a flu separately for the 25i.

    plus I managed to pick up a hive 1 system for 60 (from toolstation) so that's the programmer bit sorted too.

    productive day on the CH front!

    Just keep in mind that if you are supplying the materials yourself the engineer may change you extra to fit.
