Boiler flue that doesn't need inspection hatch?

    Hi,

    I'm doing a renovation of my flat, which involves replacing an old regular boiler by a combi to save space.

    My flat has 2 bedrooms and 1 bathroom. My builder recommended Vaillant ecoTec Pro 24, which seems to be a good choice. The new combi boiler is to be placed in a utility cupboard in the hallway, and the flue will run across the false ceiling in the bedroom to reach the external wall. Inspection hatch will be needed.

    Today my builder told me if I don't like the inspection hatch, he can use another boiler called Keston 30 Combination, which has two flues (one for fresh air, one for exhaust) but does not require inspection hatch.

    For me, while an inspection hatch is not very beautiful, I can accept it. I doubt whether my builder's claim that 'Keston 30 Combination does not require inspection hatches' is valid. I checked Keston website but didn't find any documentation saying its two-flue boilers do not need inspection hatches. Besides, I never heard about 'Keston' boilers before and I personally prefer big brands.

    I'm more inclined to stick to the original plan: Vaillant boiler + inspection hatch. What do you think? Any suggestions are welcome. Thank you.

    thanks
    Patrick

    This isn't a job for a builder.....

    It might be tricky to get a large enough gas supply for a combi depending on the existing run

    Modern Keston boilers are rebadged Ideal Logics with an adapter to twin flue and an inexplicably enormous price tag.

    Don't let your builder specify your boiler, every man to their own trade. You need a heating engineer

    Bin the builder...guarantee it'll either be an illegal job or he'll be screwing over the gas installer. And he's clueless about the regs. Always employ trades directly...you have far better protection if the job goes wrong.
