How to Clean Wall Heaters Safely

Electric wall heaters are essential for keeping our homes warm but need regular cleaning to work effectively and safely. Follow these simple steps to clean your electric wall heater:

Step 1: Turn Off the Power

Safety always comes first. Switch off the circuits supplying power to your heaters. Double-check with a voltage detector to ensure there’s no electricity running to your heater.

Step 2: Carefully Remove the Grill

If your heater has a thermostat, take your time when removing the thermostat knob. Gently use a flathead screwdriver. Rushing this step can damage the thermostat. Many force the knob off or remove the grill first, leading to potential thermostat replacement or heater replacement.

Step 3: Clear Out Dust and Debris

A regular hair dryer will do if you don’t have an air compressor or a blower-equipped vacuum. Avoid canned air; it can be flammable. Make sure the fan blades don’t spin while blowing out the dust to protect the motor.

Step 4: Thoroughly Clean the Grill

Place the grill in a bucket of soapy water as soon as you remove it. Let it soak while you clean the inside of the heater.

Step 5: Reattach the Grill Securely

Make sure the grill is completely dry before reinstalling it. Moisture inside the heater can cause damage or safety issues. When replacing screws, tighten them just snugly to avoid grill damage.

Step 6: Restore Power and Test

Turn the breaker back on and adjust the thermostat to activate the heater. Let it run for a few minutes to ensure it warms up correctly and operates smoothly. Set it to your preferred temperature.

Regular cleaning maintains your heater’s efficiency and durability. It ensures your electric wall heater keeps you warm and safe.
