Detroit Radiant SMWC-18 Variable Heat Controller: on, off and adjustable heat for small electric heaters

The Detroit Radiant SMWC-18 Variable Heat Controller is a dial control for Detroit Radiant BAH, ELX and ELD electric heaters. It turns the heat on and off and lets you adjust how much heat the heaters put out. Turn the dial when you want more or less warmth. The control comes in a stainless steel box and works with 120 volt heaters with a combined output of up to 1,800 watts. Detroit Radiant builds these controls for its own heaters, so the wiring and voltages match.

One controller can serve one or two small heaters within that limit. It does not need a contactor, a separate electrical switch used to handle power to the heaters. Need the version for 208 or 240 volt heaters? See the Detroit Radiant SMWC-36A Variable Heat Controller. The Detroit Radiant SMWC-18 Variable Heat Controller ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.
