    Favourite/Worst boilers you work on

    Thought it'd be interesting to see what everyones favourite and least favourite boilers are for working. I love a good Vaillant Turbomax Plus, and a Glow Worm Ultimate to work on. Won't touch Alpha's, think the Baxi Powermax has to be up there with one of the worst. Some of the older...

    Are Worcester boilers all that?

    Let me preface - I install and repair boilers and in my humble opinion Worcester Greenstar i aka Junior isn't a good boiler. I realise why they are very pupular - the Bosch name, the marketing (best friends with Which?), "trusted" by the big installers. Installation - Probably the hardest...

    Kw of system boilers

    10 rad system and 210l unvented with a 16kw coil Do you size to cope with full heating load and full coil kw which may be needed in a rare occasion (25-28kw) Or size for usual demand (15-18kw) I tend to go for the bigger value as there is less chance you will get a call but it’s going to cycle...

    Are storage combi boilers better than a system boiler?

    We are currently looking to replace our 40 year old vented system to a system boiler. We have had a suggestion of getting a storage combi boiler instead of a vented boiler with cylinder. Space is not a problem. I am more than happy to replace both boiler and water cylinder. We have many options...

    Evening all, I have an interesting problem. I look after twelve alms houses that had Vaillant Ecotec combis installed about three years ago by some national company.

    Modern oil boilers

    Hi, just looking for info on oil boilers and heating controls. They seem to be a bit behind gas boilers in terms of efficiency, would I be right in thinking that weather compensation and modulating output isnt common amongst the average modern oil burner? That leads me to my question, in rural...

    ROC Boilers

    ROC Boilers, do they really exist or did I imagine the whole thing? I could've sworn I tried to fix a ROC COMBI 28 HE, 47-492-01 last night, diagnosing a faulty flue thermistor, and yet here I am unable to find any evidence that they actually exist! Turns out I can order a whole new boiler from...
