Key Features of the Frost Fighter IDH200QR Heaters

Multi-Fuel Flexibility

Choose between Oil/Diesel (O/D) or Propane/Natural Gas (LP/NG) models to match your fuel availability and cost requirements. The LP/NG model features a convenient ball valve switchover system for easy transitions between propane and natural gas.

High-Efficiency Multi-Pass Heat Exchanger

The proven stainless steel multi-pass heat exchanger delivers over 81% efficiency, maximizing fuel utilization while providing consistent, clean heat output. This advanced design ensures optimal heat transfer for reduced operating costs.

Extended Ducting Capability

Features a 12" outlet supporting up to 100 feet of supply duct and a 12" intake accommodating up to 50 feet of return duct. This extended ducting capability optimizes fuel consumption and reduces heating times through efficient air recirculation.

Ultra-Quiet Operation

Operating at less than 74dB, this heater is perfect for noise-sensitive environments, including occupied spaces, events, and urban construction sites where sound levels matter.

Cold-Weather Reliability

Independent fan and combustion air systems ensure steady operation in extreme cold climates. The heat exchanger pre-heats before fan operation, eliminating cold air delivery at start-up - crucial for Canadian winter conditions.

Robust Mobile Design

Compact dimensions (52" x 22" x 36") with pneumatic wheels and handles enable easy transport across job sites. The powder-coated finish provides durability against harsh environmental conditions.

Frequently Asked Questions

What's the difference between oil/diesel and LP/NG models?

Oil/diesel models offer extended runtime with onboard fuel tanks (14-16 hours) and higher discharge temperatures (230°F). LP/NG models provide cleaner burning with convenient fuel switching and consistent supply options.

What fuel types can I use?

The Frost Fighter IDH200QR is available in two versions. One runs on Oil or Diesel, and the other runs on Propane (LP) or Natural Gas (NG). The LP/NG model features a convenient ball-valve switchover. For more details on fuel, see our guide on fuel types used in indirect-fired heaters.

Can this indirect-fired heater be used indoors?

Absolutely. As an indirect-fired heater, it vents all combustion byproducts externally, delivering only 100% clean, safe, and breathable warm air into your space. This makes it perfect for enclosed and occupied areas.

How far can I run the ducting?

This model supports a total of 100 feet of ducting. Approved combinations include 100 ft of supply duct with no return, 75 ft of supply with 25 ft of return, or 50 ft of supply with 50 ft of return.
