EDR for odd cast-iron BASEBOARD heaters?
BTU

in Oil Heating
I never seen these. 12" tall, about 2 3/4" wide. No vents in the cast-iron. Possible hold over from coal-fired boiler in Ware, MA (currently served by Homart oil boiler, by Sears-Roebuck ca. 1953). Would any of yall know an EDR calculation? Is it in a Holohan book somewhere?

I think Burnham used to make something like that. IIRC the ratings are in the "Hydronic Rating Handbook" by Tom Byrley- I know I have a copy somewhere..............All Steamed Up, Inc.

HVACNUT, exactly my thoughts. No convective currents with these, as opposed to all other baseboard I've come across, CI and fin-tube.
I did go ahead and use a standard 3.4 sq ft EDR per linear foot of baseboard. Still interested if anyone gets an exact figure on these.0 -
My thoughts as well.HVACNUT said:Where is the air transfer? I don't see any openings.
Good call Mr. Pink!8.33 lbs./gal. x 60 min./hr. x 20°ΔT = 10,000 BTU's/hour
Two btu per sq ft for degree difference for a slab0
