Best Quiet Garage Heater Reviews 2022

If you’re looking to heat your garage or workshop, you may want to consider a quiet garage heater. This is especially important if you have a bedroom above the garage or want total silence as you’re working on your projects during the cold months.

Electric garage heaters are great options if you only want a supplemental heater. While they’re one of the quietest heaters, they’re also generally more expensive than gas in almost all of North America.

The next best alternatives would be natural gas and propane wall-mounted or ceiling-mounted heaters. The initial cost of these heaters is a bit high, but they are energy efficient and operate quietly.

What Type of Space Heater is the Quietest?

You can determine the type of space heater that is the quietest by considering certain factors and general rules. Electric heaters are more silent than gas heaters because they do not have a combustion chamber.

Gas heaters manually burn natural gas or propane to produce heat energy. When gases get burned in the combustion chamber of gas heaters, it makes a distinctive noise that may distract some people. The noise is loud enough to be noticed by individuals who have a normal conversation in a room.

Electric heaters do not have a combustion chamber. Although some electric heaters produce a low buzzing sound, they are quieter than gas heaters.

Heaters that have inbuilt fans are noisier than those which do not have such systems. Although fans are supposed to speed up the process by which heated air is distributed within spaces, they end up creating a distinctive noise.

The level of noise produced by fans in heaters corresponds to their power. Highly powerful fans that can distribute heated air across large spaces make more noise than small ones.

Heaters that do not have fans are quiet but lack the capacity to distribute heat across large areas. As a result, such heaters are only suitable for warming small indoor spaces.

In principle, electric heaters without fans are the quietest. Conversely, gas heaters with inbuilt fan systems are the noisiest because of the fans’ combined effect and the combustion process in the chamber.

How can I Make my Heater Quieter?

If your heater is quite noisy for any reason, it is possible to reduce the noise and enjoy a comfortable environment.

Here are a few tips on how you can make a heater quieter.

  • Fix the motor. A faulty or old motor is one of the most common sources of noise in heaters. When the motor ages, it loses lubrication, and some of its parts become loose. If you can fix the faulty parts of the meter and lubricate it again, then the noise level will reduce dramatically. In most cases, it is advisable to replace your heater’s motor as a way of dealing with the noise.
  • Check the air ducts. If the air ducts get small for any reason, your heater will start producing a loud hissing sound. This type of sound is a result of inadequate intake of air through the ducts. You will have to either replace the duct system of your heater to minimize the noise resulting from the low airflow.
  • Ensure the filters are clean. Clogged filters make a hissing sound when air passes through them. The most effective and reliable way of dealing with this problem is replacing the furnace filters. Having super clean furnace filters will help make your heater quieter than when you have dirt-clogged ones.

Wrap Up

Finding a quiet garage heater isn’t difficult if you know what to look for. However, the level of noise a heater produces is an important factor to consider, but it’s not as important as the type of heater you choose, heating capacity, and energy efficiency of the heater.

All electric heaters produce a little bit of noise during operation. However, fan-forced heaters are noisy than radiant, oil-filled heaters, or baseboard heaters. These heaters excel at heating large rooms efficiently with little noise interruption.
