Gather Your Supplies

Cleaning your electric wall heater doesn’t have to be a daunting task. All you need is the right supplies and some patience. Gather all of the necessary items before starting: vacuum cleaner, clothes, cleaning solution (preferably one designed specifically for electric heaters), and any other tools needed to remove parts or access tight spaces.

Now that you have everything ready to go, it’s time to unplug your electric wall heater.

Key Takeaway: Cleaning your electric wall heater is easy with the right supplies and a bit of patience. 

Unplug the Heater

It’s important to unplug the heater before beginning any cleaning process. Not only is it a safety precaution, but it also prevents any electrical shocks or fires from occurring while you’re working on the appliance. To begin, locate the power cord and switch off the power at either end of the cord. If your heater has an internal fuse box, make sure to turn off all switches in that area as well. Once everything is switched off, unplug the power cord from both ends and set aside for safekeeping until you are ready to plug back in after reassembly.

Next, inspect all areas around your heater for any exposed wires or loose connections that could be hazardous during cleaning or reassembly. Make sure there are no frayed cords or broken pieces of plastic nearby that could cause harm when handling your appliance later on in this process. It’s best practice to double-check these areas before continuing with cleaning so you can avoid potential hazards down the line.

Once the heater is unplugged, it’s time to move on to vacuuming the unit in order to remove any dust or debris that may have accumulated.

Key Takeaway: Before cleaning an electric wall heater, make sure to: unplug the power cord from both ends; switch off any internal fuses; and inspect all areas around your heater for any exposed wires or loose connections.

Vacuum the Heater

Vacuuming the heater is an important part of keeping it clean and running efficiently. Before you begin, make sure to unplug the heater from its power source. This will prevent any electric shocks or other hazards while cleaning.

Start by using a vacuum cleaner with a brush attachment to remove dust and debris from the exterior of the heater. Make sure to get into all crevices and corners, as dirt can build up in these areas over time. If your vacuum has adjustable suction settings, use a lower setting for more delicate surfaces like metal grills or plastic covers on some models of heaters.

Once you’ve finished vacuuming around the outside of your heater, move on to vacuuming inside it if possible. Use caution when doing this; never put your hand inside without being absolutely certain that it is unplugged. Once again, use an appropriate brush attachment on your vacuum cleaner to reach into tight spaces within the unit where dust may have accumulated over time. Be careful not to scratch any internal components with sharp edges on attachments or tools used during the cleaning process – these could damage delicate parts which could cause malfunctions later down the line.

Finally, once you’re done vacuuming both inside and out, take care not to forget about vents located at either side of most heaters – they too need regular cleaning so that air can flow freely through them without obstruction. A soft-bristled brush should be enough for this job but if necessary use another suitable tool such as compressed air cans available in hardware stores for tougher jobs like removing pet hair stuck in hard-to-reach places within vents themselves.

Vacuuming the heater is an important first step in cleaning it. Now that you have vacuumed, move on to cleaning with a cloth and solution for a thorough clean.

Key Takeaway: To keep your electric wall heater running efficiently, regularly vacuum it both inside and out, paying special attention to vents. Use a brush attachment on the vacuum cleaner for delicate surfaces and soft-bristled brushes or compressed air cans for tough jobs like pet hair stuck in hard-to-reach places within vents.

Clean With a Cloth and Solution

Now it’s time to get started on actually cleaning your heater. Put on those rubber gloves so that you don’t get any of the cleaning solution onto your skin as this can cause irritation or even burns if left too long. Dip one corner of your damp cloth into the cleaning solution then wring out the excess liquid until only a small amount remains in order to avoid dripping while wiping down surfaces. Gently wipe down all external areas of the heater using circular motions until they are clean and free from dirt or grime buildup.

Once finished, allow enough time for all parts of the heater to dry completely before reassembling them back together again, which will be discussed in the next section.

Reassemble and Plug-In

Once you have finished cleaning your electric wall heater, it is time to reassemble the components and plug it back in. Start by replacing the front panel of the heater. Make sure that all screws are securely tightened before moving on to the next step. Next, replace any air filters or grills that were removed during cleaning. Again, make sure they are firmly secured into place before continuing.

Now it’s time to reconnect all electrical wires and plugs. If you had disconnected them from their original locations for easier access while cleaning, be sure to put them back exactly as they were found originally – this will help ensure proper operation of your heater once plugged in again. Finally, check for any loose parts or pieces inside the unit itself and tighten it if necessary before plugging it back in.


Always double-check that everything has been properly connected and fastened prior to plugging your electric wall heater back into a power source. Doing so could prevent potential hazards such as fires or electrocution due to improper wiring connections within the unit itself – safety first. Once everything looks good and secure, go ahead and plug your newly cleaned electric wall heater back into an outlet – enjoy its warmth once more.


With the right supplies and steps, you can easily get your heater looking like new in no time. Now that you know how to clean an electric wall heater, you’ll be able to keep it running efficiently for years to come. So don’t wait any longer – grab those cleaning supplies and get started on giving your electric wall heater the deep clean it deserves.
