Frequently Asked Questions

How long does a standard propane tank last with this heater?

A 100 lb propane tank contains ~23.6 gallons of propane. At 10.93 GPH consumption, it would last just over 2 hours at full output. Plan for frequent refueling or use bulk tanks for longer jobs.

What makes the Flagro F-1000T better than similar 1 million BTU heaters?

Its dual-fuel flexibility, CSA certification, electronic ignition, and rugged Canadian-built design give it an edge over other options that may require conversion kits or lack safety features.

Is this heater safe to leave running overnight or unattended?

While it includes a 100% flame safeguard system, it is not recommended to leave any direct-fired heater fully unattended. Always follow safe operating procedures and local regulations.

How portable is the Flagro F-1000T? Can one person move it?

The heater is designed with a stackable frame and handles for transport, but at 356 lbs, it generally requires equipment (like a lift or dolly) or two people to move safely.

What fuel type is more cost-effective — propane or natural gas?

Propane offers better portability, while natural gas is more cost-effective for long-term use if a supply line is available. The F-1000T makes it easy to switch between fuels based on site needs.
