    Hi
    I will be taking out a Stanley oil cooker 100000 Btu and fitting a firebird condensing boiler, it will be heating 19 rads in total but these are split by 4 zones and usually only 2 zone valves open at any one time. I'm looking for advice from someone with experience of sizing condensing oil boilers, do I go with the c35 or would the c26 be sufficient.
    Many thanks
    Ps there's also a solid fuel stove connected to the rads which will be used quite often.

    Okay ill have a go at sizing this for you...(I might be sad but I wish I was home alone:D)

    If you take that your rads have an average out put each of 1kw and your dhw 3kw leaving your heating requirements roughly 22kw the c26 would be the boiler for you.
    Bare in mind you cannot connect your condenser to the same flue as the stanley if its connected to a clay flue without using a suitable flue liner.
    Over sizing a condenser boiler is not advisable.
