CI SqFt Radiation Sizing

wcs5050

Trying to determine output. I’m using Burnham cast iron slenderized emitter chart as reference on these. 

6 column, 24” high, 26 sections, at 180degF I’m getting 10k-13k btu but am unsure on my chart understanding. Maybe someone has a better chart. 

Yes, that piece fired off the far radiator and no one has moved it. Someone had just entered the room as 6 others let go and said it sounded like a gunshot.

What a minute. What made this casting explode?

Ice, brah. Shock and awe. 

Really though. We had a cold snap in New England last week and it dipped to -12degF. Power was out for 24 at this church.

For 180degF water, 78sq ft x 170btu/sqft: 13260
