My wife & I bought an old house with steam heat ~ 6months ago in the Westchester area; the heating isn't great but I finally have some time over the holidays to try and address it; hoping this community can help.
I've had a number of plumbers visit but after reading this site for months; they clearly aren't steam people.
House: single story w/ 13 radiators - all new vents: Hoffman 40s to Gorton Ds.
Boiler: Burnham installed in 2007; a few plumbers did not that the copper risers was a wrong install.
Thermostat: Honeywell 6450 @ 65degrees; 1 CPH (no setback)
The boiler fires up for ~30 mins to maintain the temp every 70 mins or so.
Things I've done so far:
Main A (Strong Side): ~136' long from Boiler, 2.5" diameter. This main has 3 main vents; two of these were replaced w/ Gorton #1 and after the last radiator a single Big Mouth. No insulation on pipes, removed old asbestos when house purchased.
Main B (Weak Side): ~65' long, 2.5" diameter. This main has 2 main vents; one was replaced with a Gorton #1 and after the last radiator on the return is a Big Mouth. Rooms on this side are always 3 degrees colder than rooms on the Strong Side. No insulation on pipes, removed old asbestos when house purchased.
I'd like to increase the speed to heat the house as well as balance the temp, I'm contemplating building an antler for both the Strong and Weak Side so I can use two Big Mouths on each end of main.
Does that make sense? The vents in the diagram were replaced 2 days ago, 3 Gorton #1 & 2 Big Mouth.
Any help figuring this out would be greatly appreciated (Got Steam has been ordered).
