STEAM TO HOT WATER

Steamhead

One of the biggest problems on this type of conversion is the fact that hot-water runs with at least ten times the pressure of steam. This will find any weak spot that exists in pipes and radiators, causing leaks and damage to the building. I've seen jobs where this has happened and it's not pretty.

Then there's the question of whether the radiators will even work with hot-water, and if so, will they be big enough to heat the building with their output capability reduced from 240 BTU per square foot EDR to 150 BTU or so.

I've found it's much more cost-effective and much less risky to fix steam systems instead of trying to convert them. If you don't have much experience with steam, you've come to the right place!

2 pipe steam

you would be better off putting in trvs ,orfice plates,air vents and a mpc heattimer.the plates will allow you to leave the traps in the system with out rebuilding them,the trvs will regulate the temp of the room and the heattimer will be the weather dependant control with setbacks.tunstall associates,woodie tundstall,at 413 594 8695 should be able to help you.on another note your steam start up load will drop by about 30%.depending on the bldg you can cycle the mpc at about 20 min. cycles with a hi limit temp of about 130 at the pipe of the longest pipe run just before the last radiator.

Dave, how do we link to that?

I've searched that site several times and can't seem to find Contractors' Corner.....

ask

Ric who runs the site. I can't access the video & sound with dial-up (one of the days I'll get cable or DSL), so I don't visit.
