What Type of Heater is Best for a Garage Gym: Electric vs. Propane vs. Natural Gas

Based on the fuel type, you have the following three types of garage heaters available in the market.


As the name suggests, you need an electricity connection in your garage to run an electric heater. Since most of the garages have electrical power, many people opt for electric heaters as they are convenient and portable.

However, using an extension cord increases the chances of tripping over and creating a disturbance in the garage.

On the downside, you can’t use an electric heater in case of an emergency power outage.

Nonetheless, the electric heaters don’t require any regular maintenance. All you need to do is clean them with a dry cloth to remove the dust from the louvers.


You need to connect a propane tank for the smooth operation of this type of heater. Some propane heaters also need an electric connection to operate the fan to blow the warm air into the surrounding.

Many people buy propane space heaters because they are portable and lightweight. It means you can place them anywhere in the garage for directional airflow.

Moreover, you can find different sizes of propane heaters that offer 30,000 BTUs to 125,000 BTUs per hour.

A portable, non-electric propane heater is the only option in an emergency if you don’t have electricity or natural gas connection. However, these heaters are generally noisy due to the presence of the fan to blow out hot air.

Natural Gas

If you have a natural gas connection in your garage, a natural gas heater is a perfect choice. Alternatively, you need to hire an expert to install the gas piping to ensure your safety.

Many gas heaters feature a versatile design allowing you to mount them on the wall or the ceiling, which is a great convenience, especially when the garage space is limited.

Lastly, a natural gas heater is the most cost-effective solution to warm your garage.
