Thermostat Control of Vintage Steam Heat

        Comments about Remote Setpoint & Sensor - Wall Mount:

        The "one-pipe" steam heat in my 1928 Mediterranean-style building was designed with radiators intended to be always on and hot whenever the boiler was running. Finding this intolerable, most residents have cut through their radiator grills so they could turn the steam supply valve off when it got too hot & vice versa. Some, sadly, have tried to regulate temperature by opening the valve just a bit, which works poorly, and causes water damage to apartments below, if condensed steam accumulates in the radiator and pours out of the air vent!

        The "Danfoss RA2000 iPS" system provides safe and effective, thermostatic temperature control of such systems. For our enclosed radiators, we chose their combined controller-sensor that attaches to a wall, connected to a Danfoss 1PS valve that fits between the air vent and the radiator body. This valve either blocks the vent (preventing cold air from exiting, thereby reducing the space available for new, hot steam) or allows the air vent to function normally (so cold air gets pushed out and the radiator can fill with hot steam). It's not difficult to install the thing oneself.

        I've measured the system's effectiveness by logging signals from a thermocouple clamped to a radiator, and found that when room temperature is below the thermostat set-point, the radiator sits at about 200 deg F, dropping briefly to about 160 deg F when the boiler cycles off (every hour or so, as recommended). When room temperature is above the set-point, radiator temperature drops to between 90 and 120 deg F. Excellent!

        Some cautions: It seems that little gadgets controlling hot, corrosive steam have limited lifetimes. The familiar radiator vents (though it is little known) require periodic replacing, and I've had one Danfoss valve that stopped functioning sometime during the 10 years it was in place.

          Q:

          I was wondering what the min and max temp settings for this product are? Also, what is the distance that the sensor needs to be mounted at for optimal performance?

          Thanks

            A:

            The temperature range for this product is 45-86 degrees Fahrenheit. The sensor should be about 3-4 feet away at a minimum.

            A:

            The thermostat's room temperature settings are said to go from 46 deg F up to 82 deg F. These are certainly approximations. Basically, you can set the thermostat so that the air vent is always blocked (the lowest setting) or always open (the highest). Typically, you'll set it in-between, somewhere around "3" on its 5-point range.

            "Always open" means that your radiator functions as if the RA-2000 were not there. "Always blocked" means your radiator still gets warm when steam comes up, but not hot, because cold air in the radiator cannot escape through the vent, which prevents the radiator from completely filling with new, hot steam.

            The sensor simply needs to be someplace that samples the air temperature you want for the room as a whole.

            A:

            This item can be used with a one pipe steam system. There is a valve that needs to be used in combination with this item. These valves can be found on our website on the following page: http://www.pexsupply.com/pex/control/category/~category_id=789
