Quietest Forced Air Propane Heater – 2022 Reviews

Forced air propane heaters are incredibly effective at heating medium to large rooms, including garages and commercial buildings.

However, since these heaters use a fan to circulate warm air through your space, they often produce a loud blowing sound, which can be uncomfortable, especially if put in smaller spaces.

The truth is that most of these units are loud, and you’re going to have to compromise on the noise to keep your space warm as you work on your project in the winter.

But that doesn’t mean you have to pick the loudest unit – you can still find a quiet forced air propane heater for tiny rooms. And we have reviewed some of them in this article.

Quietest Forced Air Propane Heater

What is a Forced Air Propane Heater?

A forced air propane heater comprises an ignition system, a fan, and a combustion mechanism. A source of propane gas is connected to the heater via the hose. The hose is fitted with a regulator that you can use to control the amount of propane that gets into the heater.

When the pilot ignition system is set off, the propane is burned to produce heat and other products. The fan forces the heated air out of the heater into the environment.

As the hot air is forced out of the heater, it spreads across the room. The air then rises in the form of convection currents. This process of movement of air is repeated as long as the propane heater is running.

Are Forced Air Propane Heaters Safe Indoors?

Generally, forced air propane heaters are designed to warm garages, workshops, and other spaces. There are many better alternatives to forced air heaters that you can use indoors.

Nevertheless, should you decide to use a forced-air propane heater indoors, you will have to take several precautions.

Since you can get carbon monoxide poisoning from propane, it will be necessary to install a carbon monoxide detector. You will also have to ensure that there is enough ventilation in the indoor space in which you intend to use the forced air propane heater.

Do Forced Air Propane Heaters Smell?

When functioning correctly, forced air propane heaters do not smell at all. Propane itself is an odorless gas. However, when there is a leak, you will detect a foul smell. The smell is not from propane gas but a special additive to the product called Ethyl Mercaptan.

Because propane leaks are quite dangerous, you must detect a leak as fast as it starts. The use of the foul-smelling additive does the trick.

Once you detect the additive’s foul and rotten smell, then it means that there is a leakage of propane gas either from the tank or along with the hose that connects the tank to the heater.
