Top 10 Mistakes Contractors Make with Steam Heating Systems ..

#2 They try to use just one steam trap for the whole system. Steam traps belong on every two-pipe system that has dry returns, and on any system that has a condensate or boiler feed pump. The traps keep the steam from entering the return lines, going a long way toward balancing the steam distribution.

When operating a steam boiler without insulation on the main steam pipes in the basement, you’ll need a larger boiler, incurring higher operating costs.

This is a steam system so there should be no water in the radiator when the boilers off. He takes the cover off and gets douched by five or six gallons of water.

All heating units and the end of the supply main are sufficiently above the boiler water line so that condensate flows back to the boiler by gravity. In a two-pipe system, steam

What you should know about the Hartford Loop - Heating Hel

Consider a one-pipe steam system for a moment. The main works its way from the boiler header, around the basement, and then drops for the first time when it returns to the boiler. There are no return pipes below the boiler water line, so there’s no danger of losing the boiler water should an above-the-water-line return pipe break.
