Frequently Asked Questions
What kind of heat does the Flagro FRHR-100 deliver — radiant or forced air?
The FRHR-100 Series uses radiant heat, which warms people and objects directly without needing to heat the air. This makes it highly effective for drafty, open-air, or uninsulated job sites where forced air heat would dissipate too quickly.
How large an area can this 90,000 BTU heater warm?
Depending on conditions, the FRHR-100 can heat 1,500–2,000 sq ft, making it ideal for construction zones, shelters, warehouses, and equipment areas.
How much maintenance is required?
Very little. The filterless burner system is designed to run cleanly in dusty, dirty jobsite environments. With no filters to clog or replace, it’s a low-maintenance heating solution built for real work conditions.
How do I know if 90,000 BTU is enough for my space?
To determine the right heater size, you'll need to calculate your BTU requirements based on the size of your space, insulation quality, and outdoor temperatures. The FRHR-100’s 90,000 BTU output is ideal for most medium to large jobsite areas, but if you're unsure, use our BTU Calculator to get an accurate recommendation.
