Keep your garage or workshop warm and comfortable with the Dayton U31 portable electric space heater. Made of enamel and chrome, this electric heater is ideal for rugged environments and will provide years of worry-free service.

Featuring up to 5,120 BTUs of safe electric heat, the Dayton U31 distributes this heat evenly to ensure maximum comfort. In addition to its high BTU output, the Dayton U31 electric utility heater is truly unique because it offers both fan-forced and radiant heat in one convenient unit. When switched onto the low setting, the U31 provides radiant heat that replicates the rays of the sun. When set to medium, this heater gives off fan-forced heat. When you need an extra blast of warm air, this heater uses both radiant and fan-forced heat for heavy-duty heating.

Other great features include a built-in thermostat for precise comfort control and a convenient carrying handle for portability. Safety features include an automatic tip-over switch and instant overheat protection.

Comments: The sales representative was very helpful in providing a change I had to make as I almost ordered a heater that required 220 volts and I only have 120 in my work shop in the basement. Very good. I like the three speeds for the fan and the dial-up for the temperature control.
