Espar Airtronic Heaters: B2, B4, D2 and D4 Selection for Your Overland Adventures

The Espar Airtronic heaters provide reliable and economical heat for vans, trucks, and roof top tents.

Choose the B2 and B4 models for gasoline, or D2 and D4 for diesel.

They work without starting the engine. Thus, you save fuel while staying warm, even off-grid.

What is an Espar Airtronic Heater?

An Espar Airtronic heater is a forced air system.

It burns diesel or gasoline to heat ambient air.

Made by Eberspächer in Germany, it combines reliability and longevity.

Ideal for off-grid, it draws fuel from the vehicle's tank.

Thus, you stay autonomous during the harshest Canadian winters.

Differences Between B and D Series

The B series runs on gasoline. It suits gasoline vehicles.

In contrast, the D series uses diesel. It targets diesel vehicles.

In both cases, the technology remains similar.

You enjoy clean combustion and excellent efficiency.

How Does an Espar Airtronic Heater Work?

The Espar heater draws in outside air, then mixes it with a small amount of fuel.

A glow pin ignites the mixture and creates heat.

Next, a fan spreads the warm air into the cabin.

Exhaust gases vent outside.

Thus, the interior stays healthy and odor-free.

Compatibilities and Uses

The Espar heaters install in vans, overland trucks, and campervans.

They operate on 12 V or 24 V depending on the model.

For example, pick the D2 for a small van.

Prefer the D4 for a larger volume.

Add 4-season insulation to boost efficiency.

For Gasoline Vehicles

Opt for B2 or B4.

You avoid carrying a second fuel.

Your trips gain simplicity.

For Diesel Vehicles

Select D2 or D4.

They use the same fuel as the engine.

It is ideal for long road trips.

Comparison with Webasto

Espar heaters excel at high altitudes.

They work up to 3,000 m without an extra sensor.

Webasto often limits to 2,200 m.
