FAQs
1. How long does a standard propane tank last with this heater?
A 100 lb propane tank contains approximately 23.6 gallons of propane. At a consumption rate of 10.93 gallons per hour (GPH), it would last just over 2 hours when running at full output. For extended use, frequent refueling or connecting to bulk propane tanks is recommended.
2. What makes the Flagro F-1000T better than similar 1 million BTU heaters?
The Flagro F-1000T stands out due to its dual-fuel capability (propane or natural gas), CSA certification, electronic ignition, and rugged Canadian-built design. Unlike some comparable heaters, it does not require conversion kits and includes enhanced safety features.
3. Is this heater safe to leave running overnight or unattended?
Although the heater includes a 100% flame safeguard system, it is not recommended to leave any direct-fired heater running fully unattended or overnight. Always follow proper safety guidelines, operating instructions, and local regulations.
4. How portable is the Flagro F-1000T? Can one person move it?
The heater features a stackable frame and built-in handles for transport. However, due to its weight of approximately 356 lbs, it typically requires moving equipment such as a dolly or lift, or assistance from at least two people.
5. What fuel type is more cost-effective — propane or natural gas?
Propane offers greater portability, making it ideal for mobile or temporary job sites. Natural gas is generally more cost-effective for long-term use when a supply line is available. The F-1000T allows easy switching between fuel types to suit different site requirements.
