Learn more about direct heater rentals in the FAQ section below.

Are there any ventilation requirements for using direct-fired heaters?

Yes, there are ventilation requirements for direct-fired heaters. They should only be used in large, well-ventilated spaces because direct heating creates carbon monoxide, a colorless, odorless gas that can be very dangerous if inhaled.

How efficient are direct-fired heaters compared to indirect-fired heaters?

In direct-fired heating, 100% of the fuel burned is used to supply warmth, making these rental models highly efficient. With an indirect-fired heater, only about 80% of the fuel burned heats the air, so they are less efficient.

What types of fuel can be used in direct-fired heaters?

The type of fuel that can be used in a direct-fired heater varies depending on the individual model. Most direct fired heater models use propane or natural gas, and many configurations offer dual-fuel capabilities.
