Auxiliary heaters are small radiators with built-in fans. They connect, via water hoses, to your engine's cooling system. Hot water from your engine circulates through the radiator whenever the engine is running. The fan controls the heater's output. Virtually every passenger car and pickup truck already has one installed.

Incredibly versatile, auxiliary heaters are installed in boats, school buses, trucks, campers, snow machines, farm machinery...any vehicle with a water-cooled engine and a cabin that needs (additional) heat for passenger comfort.
Various models can be mounted in a wide variety of locations - inside the engine compartment. in the overhead, on the floor, under the dashboard, under seats, inside cabinets, etc.

The R-255 is one of Red Dot's most popular dual fan auxiliary heaters.

Red Dot's round tube and fin design allows heater mounting in any position using the multi-position leg brackets or a flush mount frame.
These auxiliary heaters offer a two speed motor and are encased in a coated steel housing of welded and fastened construction for rugged duty and maintenance-free operation.
The compact size, simple plumbing and high output are ideal in any application.
