Our trusted dealer Parts for Trucks, Inc. breaks down everything you need to know


Picture this: it's 2:00 AM, you're parked on the side of a snowy mountain pass, and the temperature inside your cab is dropping fast. Your engine's off to save fuel, but now you're relying on one thing to keep you warm - your bunk heater. The only question is: will it hold up?

Our valued dealer partner Parts for Trucks, Inc. recently created an excellent comparison video breaking down two of our most popular heaters in the Canadian trucking industry: the BISON 2000A and the BISON 5000A. Here's their comprehensive guide to help you choose the right heater for your needs.

What's Included in Every Kit

Both heater kits come fully equipped right out of the box, so you have everything needed for installation:

  • Pre-assembled wiring harness with high-quality connectors
  • Durable fuel lines complete with couplings and clamps
  • Air ducting that's ready to go
  • Mounting plate with all necessary screws, straps, and hardware

The 5000A kit steps things up a notch, including multiple air outlets, high-efficiency ducting, plus a reinforced mounting plate that adds extra strength - making it ideal for larger installations.


Heating Performance Comparison
BISON 2000A: Efficient Power for Smaller Spaces

  • Output: 2 kilowatts (6,800 BTUs) of forced air
  • Best for: Truck sleepers, compact RVs, and smaller space

BISON 5000A: Heavy-Duty Heat for Demanding Conditions

  • Output: 5 kilowatts (17,000 BTUs)
  • Best for: Larger interiors and extreme cold environments
  • Performance: Delivers fast, full-coverage heat when you need maximum power

Fuel Flexibility & Efficiency

Both models offer impressive versatility:

Fuel Compatibility: Diesel, kerosene, or gasoline - match your current setup without modifying fuel systems

Voltage Options: Available in 12V and 24V versions for seamless electrical integration

No-Idle Operation: Warm your space without running the engine, reducing fuel usage, minimizing emissions, and saving money

Fuel Consumption Rates

  • BISON 2000A: 0.03 to 0.06 gallons per hour (incredibly efficient)
  • BISON 5000A: 0.07 to 0.16 gallons per hour (efficient despite higher power)

Whether you're focused on staying green, extending your range, or keeping fuel costs low, both units deliver excellent performance.

High-Altitude Performance

Traveling through mountainous regions? Both heaters include automatic altitude adjustments that self-regulate to maintain performance and efficiency at elevations up to 5,000 meters (16,400 feet).

Whether you're hauling through the Rockies or driving the coast at sea level, you won't experience any drop in heating performance.

Quiet Operation & Power Consumption

Both models prioritize quiet operation, providing consistent warmth without the annoying hum or drone that can ruin peaceful rest or a quiet evening on the road.

Electrical Draw Comparison

  • BISON 2000A: 1.2 to 2.4 amps at 12V (or half at 24V) - excellent for conserving battery life
  • BISON 5000A: 1.25 to 7.92 amps at 12V - higher draw but delivers superior heating power and coverage

Choose the BISON 2000A if you need:
