    im thinking about fitting a new boiler,looking some tips on getting the right size of boiler.
    at the minute i have a grant 50/90 boiler
    if i add up the total btu's for my radiators it comes to 17,800 btu's (5.2 kw?)
    Then if i go to one of those sites (energy saving trust) and insert my house info (type of house,size of house,insulation etc...) it comes up with 24 kw
    Is the radiatior info irrelevant?
    Do I go for a 24 kw (or nearest) boiler?
    Thanks in anticipation
