* Ratings are in accordance with recommended standards established by the
Steam Heating Equipment Manufacturers association (SHEMA).
1 sq. ft. EDR is equivalent to a heat emission of 240 BTU per hour with 2 psig
steam filling a radiator surrounded by 70˚F ambient air.
To convert sq. ft. EDR to lbs. of condensate, or steam per hour, divide the sq. ft.
rating by 4.
