    No, the large pipes are actually an asset as they provide mass which acts as a buffer to prevent short cycling of the boiler. Mod/cons are low mass and short cycling is a common problem especially on...

    If duct is within the conditioned space, then it should not condensate. If it does, you have another problem - most likely too much temperature drop (delta T) across the evaporator. This is most...

    AFUE does not consider ODR.

    When ANY boiler (80 or 95%) is rated, it is with 120* return and 140* supply. If you currently have BB rads, your CI boiler is probably designed and set to run with...
