How to Maintain Electric Heaters

Electric heaters are used during the cold winter months to heat indoor room air temperatures. Portable heaters placed in occupied individual rooms are used when and as needed. Industrial electric heaters come in many shapes and sizes, and varieties including oil-filled units have internal heating elements that are not exposed to outside surfaces, rendering them almost maintenance-free. Simple designs such as boxy, fan-driven styles also require little care. Unlike gas heaters, electric heaters generate no carbon monoxide. They are a safe choice and potentially environmentally friendly, especially if electrical energy to run them is derived from windmills or solar-collection panels.

Instructions

     Turn off and unplug individual heaters, and allow them to cool to touch. Cooling the outside of the heater allows you to provide basic or thorough maintenance without burning your hands or arms. And unplugging it can help prevent electrical shock. Alternatively, wear long, heat-resistant gloves if you want to start maintenance before the electric heater is completely cooled.

     Move the heater away from the wall and into an open floor space. Check the floor space where the heater was seated to see if any wet or oily spots are present. This could mean a leak exists and a unit that is no longer safe to operate. Thoroughly inspect the outside condition of the heater on all sides. Inspect the bottom of the heater by laying it down on its side on the floor. Look for cracks, rust and peeling paint or enamel.

     Use a soft dust brush or a lint-free cloth, and remove dust from the surfaces. If the heater is a self-contained unit, wipe down the vertical housing with a damp cloth. Remove fan covers on high temperature resistance cartridge heater that blow hot air. Wipe down fan blades and brush dust from covers.

     Lubricate the fan using household utility oil such as 3-in-1 oil, or check for electric hearters manufacturer‘s recommendations. One drop at the junction where blades are connected to the rotation arm should help to keep the fan running smoothly. If the fan is used in a room with high humidity, such as a bathroom, this operation should be repeated every 3 to 6 months, or if squeaking occurs. Replace the fan cover onto the heater face.

     Return the electric heater to its operational position. Plug it in and turn it on. Check that the gauges and settings are working. Monitor the heating ability to determine a satisfactory condition. Once temperature settings are reached and maintained, the unit should be good for use.
