Venting Capacities application
Hello steam aficionados,
We purchased our first home with steam heat last winter and I have done a lot of reading and learning in the past 10 mos. I started getting massive water hammer after a month or so and had no idea what was going on or what changed. I purchased "The Lost Art of Steam Heating" (Holohan) and read it cover to cover.
After 3 tries, I connected with a tech that new more than me about my system (home warranty restrictions) and cared enough about what he was doing to take the time to teach me some more. I recently purchased "Balancing Steam Systems" (Gill and Pajek) and now I need a little advice on how to apply that information.
I have my Pressuretrol set at .5 w/1 PSI differential. The unit was cleaned during service, so I'm reasonably certain it is working properly. With pressures this low (below 3OZ CFM), Gerry and Steve's charts can't give me any information on CFM for a 3/4" pipe. I've installed a tee on the end of my steam main and want to determine how many air vents to install. A Gorton #2 seems to be the only logical choice based on price to performance.
My tee is 1-1/2" (as is the entire main), and I have room to plumb the vent lines above the main. I have 87 linear feet of main and the home is two stories. Currently, the system only vents on the return side. I think this means nothing was updated from when it was a coal-fired system. I took advantage of the warranty work to clean the original vent and double up on that side.
We had a very cold winter last year and my goal is to get proper venting in place so I can get a good idea of fuel savings this winter. Thanks in advance for your advice!
