I have cast iron radiators from American Radiator Co. How do I find out how much water they hold without having to drain the entire system and refilling?

    Dennis.

    Go to the tool bar on the left and click on the library. If you don't find what your looking for there, buy one of Dan's books. If you measure the radiator, ie: L,W,H,tubes,sections it is pretty easy to calculate BTU. Why do you need to know content? Sizing for an expansion tank??Robert O'Connor/NJ

    Old Rule of Thumb

    IN PINTS! AND PER SQUARE FOOT OF EDR!

    Column rad: 1.5 pints/sqft EDR

    Flue rad: 1.75 pints/sqft EDR

    Thin-fin tube: 0.807 pints/sqft EDR
