How to size a new stove/back boiler

    Hi Guys,

    My heating at the moment consists of OFCH and an open fire in the main sitting room (with no back boiler). We get great heat out of the open fire, but to heat the rooms upstairs (especially when we put kids to bed) we have to put on the oil as well for an hour or two - which isnt really efficient.

    I'm looking to put in an insert-stove with a back-boiler to lessen the dependency on the oil - but I dont know how best to size for my house. We have 16 radiators in the house - all double radiators. I hear talk about sizing based on Kw - but how do I go about calculating what size stove I need? Also, I hear that the number of radiators is a factor - but some of these I can turn off.

    Keen on your thougts.

    R.

    Hi Sudo
    I would presume your oil boiler would have been sizes to heat your radiators. take a look at the oil boiler it will give you the btu output. Your stove will need to be the same btu value.
    If you need to convert to Kw -- multiply your btu output 3412 that will give you your Kw/h output.

    Does the oil give you good heat and hot water when on ???

    You can size each room if you wish.
    1.multiply -- Length x width x height =
    2. Depending on insulation in house,
    Good insulation multiply your answer by 4
    Medium insulation multiply your answer by 5
    poor insulation multiply your answer by 6
    Then ADD 12,500 to your answer for your copper cylinder



    this will give an answer in btu's and to convert to Kw/h multiply the btu's by 3412 that will give you Kw/h
