    what is the EDR of this Radiator

    I am sizing a new boiler for my house. I was able to find all the EDR stats on my thin tube type radiators in Dan's book "lost art of steam heat" but I can not find any info on this radiator can anyone help? The dimensions are 9"x 6" 52". I was able to find the embossed letters on one of the ends "ABCO CONVECTOR". I believe the EDR to be quite high because this is the warmest room in the house.

    At this point my total sq-ft of steam requirement is 466 not including the mystery radiator or a pick-up factor. In my total I have included all of the disconnected radiators, that I am aware of.

    I am a Professional restorer of Victorian homes and have what knowledge I have been able to glean from Dan's good books and the general know-how that goes along with rebuilding old houses, but in no means a professional of steam heat. So I will gratefully accept all the input you folks have to offer in my great boiler replacement adventure before winter sets in.

    boiler sizing

    thanks for the chart that completes my calulations for sqft
    I have a total of 538 x 1.33= 715sqft x 240= 171,655 btu gross output, correct?
    what boilers have you found to be the best value for the buck these days?

    You don't need to add

    the pickup factor of 1.33. It's already figured into boilers' NET ratings.

    With a load of 538 square feet, and if you're firing oil, there's only one boiler: Burnham's Mega-Steam #MST-629.

    this is a wet-base boiler with a power gas burner.

    The wet base almost completely surrounds the flame with water-backed cast-iron, unlike an atmospheric gas boiler where the flame is completely below the boiler sections. This makes it more efficient since less heat is lost from the base. It also lets you switch fuels without buying a new boiler.
