An indirect-fired diesel heater is a common choice for climate control on construction sites, outdoor events, and other spaces requiring temporary heat. The heater can be installed for temporary use indoors or outdoors. If installed indoor, the flue must be vented to the outdoors by an HVAC professional. The heater is capable of temporarily heating 2,000 square feet with standard 8′ ceiling height, depending on factors such as building envelope, air handling units for air distribution, and other factors. The heater is ideal for the cost-conscious consumer. The 100,000 Btu Economy Diesel Indirect-Fired Heater is widely-used by Disaster Restoration professionals.  The 100,000 BTU Indirect-Fired Diesel Heater will cycle itself off and on to maintain the desired temperature. A return air duct can be used to bring heated air back from the space to gain increased efficiency. The heater has a 4-pass burner chamber, ensuring maximum efficiency and is ductable up to 20′. The heaters can be accessorized with an optional duct adapter for flexible ducting, tie-down brackets, and/or external fuel kits. Indirect-fired heat means all products of combustion are expelled out of a flue stack, while fresh clean air runs across the heated chamber, and is delivered to the space. Unlike direct-fired “barrel” type systems, there are no exposed flames or fumes.

PLEASE NOTE: Power requirements are (1) 15 amp circuit breaker/standard wall outlet. Heater requires diesel fuel, sold separately. We recommend the purchase of (1) 12″ High Temperature Duct sold in 20′ sections.
