Cast iron baseboard btu’s

vizio

I have a customer with a 6 tube 19” high ,7” deep ,20 Section , 35”long hot water radiator. Each section is 1.75”thick. How many btu’s will it supply?

I can't find that radiator in my book, but a four tube, 20" high, 7" deep is 2 1/4 square ft/ section so:

2.25 x 20 sections=45 sq feet of steam. 45 x 240=10,800 btu/hour on steam

An ARCO radiator by American Standard shows that the EDR is 2.3 sq ft per section. So, a 20 section rad of that size has an EDR of 2.3 X 20 =46sq ft. 180degree water would yield 170 btu/sq ft or 7820BTU/hour. If you are interested in down loading the ARCO catalog, go to the "main site -museum-radiators. Hope this helps.

@vizio, my bad. Thought it was steam. Looks like @retiredguy found it
