Frequently Asked Questions (FAQs)

How does a radiant heater work?
A radiant heater uses infrared technology to transfer heat directly to objects and people in its path, much like the sun. This is different from convection heaters, which warm the surrounding air. This direct heating method is more efficient in open or drafty environments.
Are radiant heaters safe for indoor use?
Many radiant heaters are safe for well-ventilated indoor spaces. Always check the manufacturer's specifications. For example, direct-fired propane heaters like the Flagro F-150 are designed for construction sites with adequate ventilation. Always ensure you follow safety guidelines and have proper airflow.
What is the difference between a radiant heater and a forced-air heater?
A radiant heater is quiet and heats objects directly, making it ideal for targeted warmth. A forced-air heater uses a fan to circulate hot air, which can be less efficient in large, open spaces but heats an enclosed area more quickly. For jobs requiring widespread air circulation, a direct-fired heater like the Flagro F-375, paired with the Flagro B-375 High Efficiency Fan, can be a powerful combination.
Are radiant heaters energy-efficient?
Yes. Because they provide focused heat exactly where it’s needed, radiant heaters are one of the most energy-efficient solutions available, especially for industrial and outdoor applications. You don't waste energy heating unused space.
