Dan Foss Thermostatic Radiator Valve

Dan Foss Thermostatic Radiator Valve

If you own a one-pipe steam heating system and your rooms are overheating, a Danfoss thermostatic radiator valve may solve your problem! You’ll have the ability to control the temperature in individual rooms preventing overheating and saving fuel.

But proceed with caution! Installing Danfoss thermostatic radiator valves on a single pipe steam heating system requires certain parameters and in this video, I’ll point out how to avoid the issues I ran into early in my career, Stand by!

Happy Plumbing

ATTENTION: Condo, Co-Op, and Apartment residents. I do not recommend using these thermostatic radiator valves as it’s been my experience that these dwellings operate their steam heating systems in EXCESS of the 2 p.s.i. limit. They just do not work properly at operating pressures above 2 p.s.i.
