Ultra Quiet Garage Heater 2022 Buying Guide

Low Noise

A garage heater is not an everyday purchase, so ensure that you choose one that doesn’t ruin the ambiance with loud humming sounds, beeps and fan noises.

Whether you choose an electric, gas, propane, forced air, hydronic or other model, there are plenty of quiet garage heaters to choose from.


From commercial units that can heat thousands of square feet to portable units that serve smaller spaces better, your choices are virtually unlimited. 

Alternatively, buying a smaller capacity unit won’t help you if you are looking to heat a fairly large space. To calculate the heating capacity you need, consider the room’s ceiling height, square footage and existing insulation.


Electric, gas, LP, forced-air, hydronic – the choices seem endless, but making a decision is not that hard if you carefully consider your needs. A hydronic heater may be best around children and pets, while a high-powered propane heater may work better for a large garage where more than one person works regularly. 

In the end, it boils down to your specific needs, so consider the pros and cons we’ve outlined when choosing the right type of heater for your garage. Read also: Best Ultra Quiet Pellet Stoves and Best Quiet Electric Wall Mount Heaters 2022
