We hope that this article will help you to identify and resolve any issues with your baseboard heater’s odor, and provide you with peace of mind and comfortable living space.

#1 Dust Accumulation On The Heating Element

One possible cause of baseboard heater smells is dust accumulation on the heating element.

If a baseboard heater hasn’t been used for a while, dust and other particles can collect on the heating element.

When the heater is turned on, the dust can burn, emitting a burning smell from the baseboard heater.

This is a common issue that many homeowners experience with their baseboard heaters.

While it may not pose an immediate danger, it can be unpleasant and can cause discomfort for those with allergies or respiratory issues.

Additionally, if the dust accumulation is severe, it can potentially cause a fire hazard.

In addition to regular cleaning, it’s important to address any underlying issues that may contribute to dust accumulation, such as poor ventilation or air quality.

Investing in an air purifier or ensuring proper ventilation can help reduce the amount of dust in the air, which can, in turn, reduce the amount of dust that accumulates on the heater.

#2 Chemicals or objects placed on the heater

If chemicals or objects are placed on top of the heater, they can heat up and emit a foul odor. This is particularly true for plastic or synthetic materials, which can emit a burning plastic smell from the baseboard heater.

This issue can be more challenging to prevent, as it may involve changing behaviors or habits. One important step is to avoid placing any objects on the heater, even temporarily, as they can become hot and emit a smell.

This includes items such as clothing, bags, or even decorative objects.

If chemicals or other materials must be placed near the heater, ensure that they are heat-resistant and safe for use near a heating source.

Avoid using any materials that are made from plastic or synthetic materials, as these are more likely to emit odors when heated.

If you do notice a chemical or burning plastic smell from the baseboard heater, it’s important to address the issue promptly. This may involve removing any objects from the heater or relocating them to a safer location.

If the odor persists, you may need to consult with an HVAC expert or electrician to diagnose the issue and ensure the safe operation of the heater.

#3 Overheating due to a malfunctioning thermostat or other issues

Overheating due to a malfunctioning thermostat or other issue is another possible cause of baseboard heater smells. If a baseboard heater is overheating, it can emit a burning smell.

This is particularly dangerous, as it can potentially cause a fire hazard. If you suspect that your baseboard heater is overheating, it’s important to take immediate action. One possible cause of overheating is a malfunctioning thermostat.

The thermostat controls the temperature of the heater, and if it’s not working correctly, the heater may continue to heat up beyond the desired temperature. This can cause the heater to emit a burning smell.

To prevent this issue, it’s important to ensure that the thermostat is installed and functioning correctly. Regular maintenance and inspection of the thermostat can help identify any potential issues before they become a hazard.

#4 Mold or mildew growth due to exposure to moisture

If a baseboard heater is exposed to moisture, mold or mildew may grow inside the unit and cause a musty smell when the heater is turned on.

Mold or mildew growth can occur when there is excess moisture in the air, such as in damp or humid environments. This can be particularly problematic in areas such as bathrooms or kitchens, where humidity levels are higher.

To prevent this issue, it’s important to address any underlying moisture issues in the home.

This may involve using a dehumidifier or improving ventilation in damp areas of the home. Additionally, it’s important to avoid placing any objects or materials near the heater that may hold moisture or contribute to humidity levels.

If you notice any signs of faulty wirings, such as frayed cords or loose connections, it’s important to have them repaired or replaced immediately to prevent potential hazards.

How To Get Rid Of Burnt Hair Smell From Baseboard Heaters?

As if the smell of burning dust and grease wasn’t bad enough, one of the more unbearable odors is often that of burned hair.

This typically indicates that either pet hair or human hair is built up in the heater.

If you have pets that spend time indoors, then it’s recommended you clean your heater more often.

As a rule, if you have pets, then you should clean your heater once monthly. It stays clean and odor-free.

Sometimes rubber, plastic, and other materials can also build up in the heating element or the vents of the heater.

If this is the case, then you’ll probably notice a slightly different, stronger smell.

You can self-examine your electric baseboard heater after you have turned it off and allowed it to cool down.

  • You should first take the cover off the heater. The heater cover is generally attached by one or two small screws.
  • You can remove these screws with a screwdriver, paying close attention to gently lifting the cover.
  • The screws or caps are generally located on the side of the unit. If the baseboard cover is a snap-on variety, gently remove the lid and place it to the side.
  • After you have removed the cover of the electric baseboard heater, the heating element will be exposed, and you will be able to see how much dust and residue has attached itself.
  • Remove visible pieces of debris. If there are large chunks of dirt or other particles, remove these with your hands and dispose of them. You can then clean the heating element with a vacuum or damp cloth.
  • It is essential to be gentle when making contact with the heater and try not to bend or damage the heater fins.
  • You can remove any dust located under the heating element or in any other hard-to-reach areas with a damp toothbrush.
  • Alternatively, you can use a soft paintbrush to reach between the fins to dust off areas in the back of the heater.
  • Clean off the underside of the cover with a damp cloth before reassembling the heater.
  • Finally, replace the cover and reattach any screws.

If you ever smell an electrical burning smell, this could mean that there is an electrical problem. If it doesn’t go away after one or two cycles, it could be a more serious issue that needs investigating. In this case, it’s always recommended that you contact a trained HVAC technician straight away.

How Often Should Baseboard Heaters Be Cleaned?

The frequency of cleaning baseboard heaters can vary depending on several factors, such as the environment in which they are located and how often they are used.

However, here are some general guidelines for how often baseboard heaters should be cleaned:

Are you concerned over burning smells after firing up their heaters for the first time ? This could be due to various reasons including dust, hair of pets and dirt etc.

  • Surface cleaning: The surface of the heater should be dusted regularly, at least once a week, to prevent the buildup of dust and debris.
  • Fins or grilles: The fins or grilles of the heater should be vacuumed or cleaned at least once every few months to prevent dust accumulation and ensure proper airflow.
  • Deep cleaning: A deep cleaning of the heater, including cleaning the interior, should be done once a year or as needed. This involves turning off the power to the heater, removing the cover, and cleaning the fins or grilles, as well as any other components that may be accessible.

Investing in an air purifier or ensuring proper ventilation can help reduce the amount of dust in the air, which can, in turn, reduce the amount of dust that accumulates on the heater.

Where Should You Position Your Baseboard Heater?

Baseboard heaters are best placed underneath a room’s window. This is because the cold air coming through the window will be heated before it reaches people in the room.

Additionally, with the warm air of the heater rising, it reduces the condensation, which would generally form on the glass of the window. By placing the heater below a window, you are slowing down the heat transfer and heating the room.

Make sure that you keep a small gap between the bottom of the heater and the surface of the ground. Your heater should sit at least two centimetres above the floor or carpet. This will allow the cooler air on the story to flow through the electrical element of the heater.

It is vital that you keep foreign materials at an appropriate distance away from your heater. Fabric, plastics, and other flammable materials should never be put near an electric heater.

If you’re unsure of the guidelines surrounding foreign materials, an HVAC technician can assess your heater clearance and provide you with adequate support.

Electric baseboard heaters are an economical and popular method of heating homes across the US. They are reliable, affordable, and provide a quick and reliable heat source to a room or small apartment.

Baseboard heaters are a safe option for people with either small children or pets. This is due in large part to the fact that they remain cool to touch.

They are also sturdy and unable to be easily knocked over. This makes them a valuable purchase for families on a budget.

In order to get the most value from your heater, it’s crucial that you clean your device – at least once at the start of the colder season and once midway through the season. Again, if you have pets, then you will need to clean your heater more frequently.

While a burning smell being emitted from these types of heaters has been known sometimes to occur, this is generally no cause for concern.

This type of odor indicates that there is a build-up of dust or grease with the heater fins. If this is the case, then a pure vacuum and wipe down of the heater’s interior should quickly solve the problem.

However, if the annoying smell still permeates the room, it’s time to call an HVAC technician to impact your baseboard heater’s efficiency and safety.

Baseboard heaters are generally inexpensive and come in a range of styles. You can purchase them from homeware stores or any number of reputable online department stores.
