10 Best Garage Heaters Propane 2026 in the United States

The Reznor UDXC-60 propane garage heater is a solid choice if you need reliable, efficient heating for a space between 1,200 and 2,000 square feet like a garage, workshop, or small warehouse. Its 60,000 BTU output is strong enough to warm medium to large indoor areas effectively, and it runs quietly thanks to a low noise forced air fan, which is nice if you spend a lot of time in your shop. The heater is designed to be mounted on the ceiling or wall, which helps save floor space, although mounting brackets are sold separately. It includes a propane conversion kit, so you can switch fuel types if needed, adding some flexibility.

Its heat exchanger is made from durable titanium-stabilized aluminized steel, meaning it’s built to last and comes with a long warranty—nine years on key parts, which is reassuring. On the safety side, it features an integrated circuit board with clear status lights and a built-in disconnect for easy servicing and safe operation. The unit weighs 71 pounds, so while it’s portable in a sense, it’s not something you’d move around frequently.

Fuel consumption is efficient given the 83% thermal efficiency rating, helping keep propane use reasonable. If you need a dependable, quiet, and efficient propane heater for indoor large garage or workshop spaces, this model fits well, but be prepared for a somewhat involved installation and no smart controls.

The Empire Comfort Systems Direct-Vent Wall Furnace delivers a solid heat output of 35,000 BTUs, making it suitable for warming medium-sized indoor spaces like garages or living rooms. Its direct-vent design enhances safety by drawing air from outside and venting combustion gases directly out, which is a big plus for indoor propane heaters. The wall-mounted cabinet style saves floor space, but it means the unit isn't portable—you’ll want to install it where you plan to keep it long-term.

The heater uses liquid propane or natural gas. While the beige finish is neutral, the design is functional rather than stylish. Its size (around 37" wide by 28" tall) means it needs enough wall space for installation. It’s not compatible with smart home systems, so no remote control options via apps.

This heater is well suited for homeowners looking for a wall-mounted propane heater that provides steady warmth for indoor garages or similar areas, especially where safety with venting is important. However, if you need a portable unit or want detailed fuel efficiency information upfront, this model might not meet those needs.

The Empire Infrared Heater delivers a solid 30,000 BTU output, which is enough to comfortably heat spaces up to about 1,500 square feet. This makes it a good choice for larger garages or workshop areas where consistent warmth is needed. Its radiant heating method efficiently warms people and objects directly rather than just heating the air, which can feel more natural and quicker in drafty or open indoor spaces.

The heater is designed for wall mounting, saving floor space, but it also comes with a pedestal form factor, giving some flexibility in installation. Portability is limited since it weighs 36 pounds and is intended to be fixed in place rather than moved around frequently. It runs on liquid propane and does not feature smart home compatibility, so it operates independently without remote app control. Safety features include adjustable temperature controls which help prevent overheating, a useful aspect for indoor use.

This heater suits homeowners looking to warm up their garage or similar indoor spaces with a dependable, straightforward propane-powered infrared heater that emphasizes effective heating and basic safety controls.
