: A-B) i know they are in place and they look new.
: both of the troublesome heaters did work initially(after i got them pitched correctly) athought they only heated partway. and after that they stopped heating altogether again. I noticed the steam vents from those 2 heaters donot hiss or anything also.
: So should my next step be to take off the steam vents and see if they are clogged? should i test to see if i get steam through the heaters with out the vents on?
There are other reasons for them not steaming consistently, like the downstairs main vent is not in the right place, is not working, is not large enough, so not enough steam gets to the radiator, just some steam and air, the runouts from main to riser is wrong size or not sloped right, the main has a dip that traps water.
The wrong valve is on the radiator with a seat that is too high so traps water in the radiator, or the radiator has a dirt blockage.
: C)i will have to check the sizes they are also. what are the typical sizes used for a 2 story home? is there any guideline as to how far from the boiler it is or anything
: thanks for your help
There are no typical sizes for custom steam systems (which every one is). If it is too small, a larger hole is needed - by experimentation. An adjustable can be easier than switching many in.
