Confusion about radiator output?

    hello folks,

    I am buying rads for a house and have the btus and sizes made up. I have gotten a few quotes and I cannot understand how 2 rads of exact same size can have such a different heat output?

    For example from one builders providers, a quinn rad 500mm x 1500mm double panel,is quoted as having 11349 btu. Another builder provider, with 500mm x 1500mm double panel (dont know make) quotes it as having 7825 btu ! Its the same for all the rads. Surely the heat output is a simple formula where the surface area is multiplied by the water temp, or something to that effect. Is it trickery on the part of some manufactures to obtain higher output values on their rads by adjusting water temp or something? Does anyone know if there really is a difference between the different rads?

    Many thanks for your time,


    Eamon

    Not an expert at this but some radiators are "high output".
    Runtel used to be a good manufacturer.
    Like buying a car. See what you want and what you can afford.
