converting from steam to hot water boiler

Blackmajah Member Posts: 12
I have a steam boiler with a one pipe radiator system. The boiler needs to be replaced (coal boiler that was converted to gas).

The radiators are old American Standard cast iron. All are 4 tube except for one 7 tube. I believe they are hot water radiators (the sections connect across the top as well as bottom with push nipples) that were just used with steam instead. Each push nipple on the end can be opened by removing a hex nut (2 1/2" diameter)

If so is it possible to convert one pipe steam to hot water?
Are there comfort benefits to hot water over steam?
Or would it be too costly to convert to hot water and should I stay with steam?

I thought hot water would be more comfortable since it wouldn't have a lag time of waiting for the boiling water to produce steam.

    A single pipe steam system, when working correctly, is a thing of beauty. Hot water systems require 2 pipes and uasaly a pump.

    In short, replace the steam boiler with a new steam boiler. Don't forget keep the pressure set LOW, it works better that way.
