One-Pipe Steam System

David Kelley

I have a one-pipe steam heating system. There is one thermostat controlling the entire house and I would like to add additional zones (possibly one zone for every radiator).
I am aware of the Danfoss Thermostatic Radiator Valves, but I would prefer a digital system. Plus, I'm told that those are best suited for over-heating situations.
Is there a control system on the market that would control the radiator air vents electrically?
Thanks.

That could get tricky and costly - my friend

You really are better off taking the time to balance the whole system with a combination of main vents and radiator vents. Also, a Nice Honeywell T-87 (round) works best with a steam system. Try this first. A pro will be $$$ well spent. Trvs are made by Danfoss and Tunstall. Mad Dog

Noel put me on to them

There are in Mass. They make replacement steam traps and capsule rebuild kits for just about every trap ever made. They have also, duplicated all kinds of obsolete steam valve parts that I needed. They are also very reasonable and the turnaround on an order cannot be beat. I get most stuff within 2-3 days of placing the order - if needed overnight. They also make all kinds of TRVs. Ask for Woody...tell him Mad Dog and Noel sent ya. They are outstanding!!!!!!! 800-423-5578 or www.tunstall-inc.com
