Thank you very much. I will figure it out and let you know. We do have a baseboard in our bedroom that is 6ft. long and do not seem to have trouble with banging.
Just out of curiousity, where does 650 come from? Mostly I ask because I am a math teacher and thought this would make an interesting use of math in the classroom.
: The most accurate way to know how much heat is required in a room is to do a heat calculation estimate. This can be done using the free estimator at http://www.hydronic.net
: Then the result of the heat loss estimate would be divided by 650 to know how many feet of baseboard would be required.
: Some people guesstimate the heat required by multiplying the cubic feet of an uninsulated 1940's house by 8. Then they divide this by 650 to find the feet of baseboard.
: Use 1-1/4-inch commercial baseboard sloped slightly toward the connecting steam pipe and use a steam vent on a riser nipple one foot from the far end of the baseboard run from the connector pipe. Better yet, use a cast-iron baseboard. Even then, it is possible to have a banging baseboard. The standing cast-iron radiator is a better choice.
