Stop letting all the heat from your fire go up the chimney! Grate heaters are a great and affordable way to turn your existing fireplace into more energy efficient heat producer. A blower circulates room air through the hollow tubes which are heated by your fire. Blower can typically be installed on the right or left side for easy access to electrical outlet. Be sure and select the right size grate heater for your fireplace opening. These units work great when combined with fireplace doors.
