how to make a fan heater quieter


Noisy fan heaters can be very annoying and disruptive in your home. They emit loud noises which can disrupt sleep, interrupt conversations, and cause stress and irritation. Fortunately, there are steps you can take to make your fan heater much quieter than it currently is. In this article, we’ll discuss the different ways you can make your fan heater quieter, so you can finally enjoy a peaceful and quiet environment in your home.

Keep Your Fan Heater Clean and Maintained

Keeping your fan heater clean and well maintained is the first step to making it as quiet as possible. Dust, dirt, and deis can accumulate in the fan and reduce its efficiency, forcing it to work harder and make more noise. Make sure you regularly check the fan grilles, blades, and filter for any signs of dirt or dust and remove them using a vacuum cleaner or compressed air. You should also check for any damages or worn components, such as loose screws and worn bearings, which can make your fan heater noisy. If you need to replace any parts, make sure you check the manufacturer’s recommendations for the appropriate replacements.

Reduce the Fan Speed

If your fan heater has a variable speed setting, reducing the fan speed can help make it quieter. Reducing the fan speed also reduces the airflow, so the air can’t reach the required temperature as quickly, so the fan doesn’t have to work as hard. However, it’s important to be careful when reducing the fan speed because it could lead to overheating.

Install Acoustic Insulation

Acoustic insulation is another great way to reduce the noise coming from your fan heater. Acoustic insulation reduces the transmission of sound waves and makes it difficult for sound to pass through. Acoustic insulation can be made of a variety of materials, such as glass wool and foam, and should be installed in the walls or ceilings near the fan heater. This will help to absorb the sound waves before they reach other parts of your home.

Lengthen the Ducting

This may seem counterintuitive, but lengthening the ducting on your fan heater can actually help to make it quieter. This is because the longer the ducting, the more fogging occurs as the air passes through it, reducing the sound of the fan. If your fan heater has a flexible ducting, try to increase the length of it, but take caution as longer ducts can restrict the flow of air and reduce the efficiency of the fan heater.

Change the Fan Blades

If your fan heater has plastic fan blades, these can be particularly noisy as they are rigid and lack any cushioning against the housing. Changing the fan blades with metal or rubber-tipped blades can help to reduce viations and therefore noise. Additionally, wider blades move through the air more quietly, so if possible, you should change your fan blades to wider ones to further reduce the noise.


Fan heaters can be extremely annoying and disruptive if they’re too loud. Fortunately, there are ways to make them much quieter. Keeping your fan heater clean and maintained, reducing the fan speed, installing acoustic insulation, lengthening the ducting, and changing the fan blades can all help to reduce the noise coming from your fan heater. So, if you’re struggling with a noisy fan heater, try some of the tips outlined above and you should soon be able to enjoy a peaceful and quiet environment in your home.
