Indirect Fired Heaters

Indirect heat eliminates combustion products, which can cause dizziness, burning eyes and nausea. The unit can be kept a safe distance away from party tents by connecting ducts to the front cap outlets. Indirect fired heaters use significantly less fuel than direct fired heaters since your worksite can be totally closed in and there is no need for ventilation that direct fired heaters must have.

A portable indirect fired heater is a mobile furnace with a fan forcing air over a heat exchanger where combustion occurs internally and fumes are exhausted through a stack. Heated air is delivered to heat areas where clean breathable air is needed. Indirect fired heaters are typically installed outside with warm air ducted to interior area/s to be heated. Alternatively, they technically may be installed inside with the exhaust ported outdoors using flue materials available at the local hardware store; however indirect fired heaters can be loud when used in interior spaces and safety, regulations and fueling are potential issues of the user's responsibility. Smaller indirect fired heaters typically have an on-board fuel tank. Larger models often utilize fuel from a separate fuel tank plumbed to the heater.

Direct Fired Heaters

Direct fired heaters are built rugged and durable specifically for the construction industry's harshest winter conditions. These heaters are clean burning, efficient, and portable.

A portable direct fired heater has a fan forcing air past an open flame, delivering heated air that contains exhaust fumes and odors. Direct fired heaters are for use in open or well ventilated areas such as delivery bays, unoccupied areas, etc. Sometimes known as "salamander" heaters, direct fired heaters offer an economical way to provide heat, providing there is not a need for people to be working in the heated space.

Radiant Heaters

Infra-red radiant heat is emitted aided by a reflector to warm people and objects, not atmosphere. Infra-red heat is localized, because the energy is only released when it encounters a solid mass. Ideal for drafty locations, also suitable for curing paints, glass-fibre, and drying out damp walls.
