King PHM-1 is a portable utility heater with two heat settings (1300 W and 1500 W) that can heat up a room quickly and efficiently. It has an automatic tip-over safety feature that turns the unit off if it is tipped or tilted while in operation, and an automatic overheat safety control device that shuts the heater off if a potential overheat temperature is reached. The heater also has a thermostat that allows you to set the desired temperature, and it will automatically maintain that temperature by turning the heater on and off as needed.
