We specialize in installing Webasto heaters, the gold standard in the industry for reliable warmth wherever your journey takes you. Perfect for van adventurers who value efficiency, safety, and comfort on every journey.

What is a fuel heater?


Fuel-Sipping Efficiency
This heater draws a minimal amount of fuel (gas or diesel) directly from your van’s tank—less than half a gallon for an entire cold night.
Powerful Warm Air Circulation
Equipped with a fan system, it distributes warm air evenly throughout your van, ensuring consistent comfort.
Safe and Warm
Fumes are safely exhausted outside the van, so you can rest easy knowing your space is warm and secure.
Highly Effective
Designed to perform even in sub-freezing temperatures, it keeps you toasty no matter how cold it gets.
We offer 2 options - each in gas or diesel, depending on your needs:

  • 7,000 BTU/hr Unit: Compact and efficient, perfect for most conditions
  • 12,000 BTU/hr Unit:  Higher output model, suitable for the harshest, extreme conditions and highest altitudes

What to know about your heater installation:


The best spot for installation is beneath the passenger seat, maximizing space and functionality in your van. If this spot is not available, please chat with us so we can determine the optimal location in your van.
The heater is safely tapped into your van’s fuel tank for seamless operation with minimal fuel usage.
It’s connected to your electrical system to power ignition and controls efficiently.
Easy-to-use controls are installed for precise temperature management at your fingertips.
The unit is carefully calibrated to ensure optimal performance, even at high elevations.
Our experienced team completes the entire installation process in just one day, so you can hit the road without delay.
