EDR Ratings for Thin Tube Radiators

MikeyB

Looking for some EDR Ratings for some Thin Tube Radiators I have, the only chart i came across that had sizes/style close to the rads i have is the "Replacement Boiler Sizing Chart" . Cant seem to find them in Dans EDR book, but look like US Rads, if any one has some more info on this style of rad i appreciate it, there are no names or any other info on these rads. See attatched pics. Thanks

#sections X EDR = radiator rating

All you have to do is know how many tubes per section, how many sections, and how high. The boiler sizing chart has a section that is specifically for thin tube radiators on the second page, what part of that do you not understand?

I understand how to size the rads with that chart, just curious if anyone knows what brand they are.

Hard to tell

Unless you find a name on any of the sections it could be hard to tell. A lot of different companies made thin-tube or slenderized radiators, and they all look pretty much the same. I have Burnhams and American Standards, and while I can tell them apart at a glance now, I never realized I had two different brands until I saw the raised lettering on one of them while I was cleaning it.

Use

the Burnham Slenderized charts in E.D.R. By the time this type of rad came out the ratings were pretty much standardized.

Thanks guys, I found the American Standard listings in the Library section, they seem like a good match as well
