Ideal for construction contractors, event organizers, and industrial managers across Canada, this unit keeps your job site productive and your crew comfortable, no matter how low the temperature drops. 
With its best-in-class quiet operation and exceptional fuel efficiency, the IDH500QR is the ultimate temporary heating powerhouse.

Unmatched Performance for Demanding Environments

The Frost Fighter IDH500QR is designed to solve your biggest heating challenges, ensuring your operations continue without interruption.

• Powerful, Fume-Free Heat: With a massive 500,000 BTU/h output and 4,800 CFM of airflow, this indirect-fired heater provides clean, breathable warm air. Because combustion byproducts are vented externally, it's the perfect choice for enclosed or poorly ventilated spaces where air quality and safety are top priorities.
• Ultra-Quiet Operation: Operating at less than 68 dB, the IDH500QR is one of the quietest industrial heaters in its class. This allows you to work in noise-sensitive areas, near residential zones, or overnight without causing disruptions.
• Dual-Fuel Flexibility: Easily switch between Oil/Diesel and Propane/Natural Gas with a simple ball valve. This feature gives you the freedom to choose the most cost-effective or readily available fuel source, protecting your project from supply chain issues and price fluctuations.
• Extended, Uninterrupted Runtime: The standard 42-gallon fuel tank (60-gallon optional) offers up to 14 hours of continuous operation, minimizing the need for refueling and maximizing productivity on long shifts.
• Superior Efficiency: Featuring a multi-pass stainless steel heat exchanger, the IDH500QR boasts over 81% efficiency. This means more heat from every drop of fuel, lowering your operational costs and environmental footprint. The standard recirculation capability further improves fuel savings by reheating already-warmed air.
  

Key Features of the Frost Fighter IDH500QR Indirect Fired Heater

• Robust and Mobile Design: Built with heavy-duty components and 6-ply pneumatic tires, this heater is easy to move across rough job site terrain. Its dimensions are designed to fit through standard 36" doorways.
• Extended Ducting Capability: A high static pressure blower allows for duct runs of up to 100 feet per outlet, giving you the flexibility to deliver heat precisely where it's needed. The unit supports dual 12" outlets or a single 16" outlet. For optimal performance, pair it with durable ducting like the Frost Fighter Thermoplastic Heat Supply Duct.
• Safety First, Always: The IDH500QR is fully CSA and ETL certified, meeting rigorous North American safety standards. It features a fully insulated, "cool-to-touch" jacket to prevent burns and an environmental spill containment system on oil/diesel models to protect your worksite.
• Easy to Control: This industrial heater is compatible with a remote analog thermostat for precise temperature management, enhancing comfort and efficiency.

How to Size a Heater

To size a heater, first measure the square footage of your space. Multiply by the recommended BTU per square foot:

• 25–30 BTU for insulated indoor spaces
• 40–60 BTU for typical job sites
• 60–80 BTU for drafty or exposed areas

Choose a heater with slightly higher capacity to ensure reliable performance.
