I want to replace two central heating radiators for more efficient ones in our living room. I have looked at various tips on how to calculate the required btu/wattage for the room but each method produces a different result. They vary from approx 2900 watts to 4284 watts.

Any suggestions please?

    The only reliable electronic calculator available online is the Stelrad Stars.

    Personally I stick to the industry standard Mears calculators and do it by hand. Takes a fraction of the time and is reliable.
