What is the High Altitude Kit? 

The High Altitude Kit is REQUIRED for Vans expecting to use their heater 2000m-3000m above sea level. The High Altitude Kit comes with a height sensor that measures atmospheric pressure & sends it to the ECU to adjust the Espar’s power. Basically, the High Altitude Kit helps the Espar handle higher altitudes than normal by reducing the Espar’s power by ~9& per 1000m. Thankfully, the new S2 D2L Heater has the High Altitude Kit built in, so you do not need to worry about an annoying installation.

What does this product operate like?

The heaters made by Eberspacher control your climate. They are air heaters that operate like forced air furnaces. They use your vehicle’s fuel and power supply so that you do do not idle your machine while driving.

How loud are the heaters?

They actually are very quiet and should not be noisy at all. The new S2 D2L Heater is significantly quieter than the original D2 heater.

Can I use these Airtonic heaters with other devices from Eberspacher’s inventory?

Yes. You can. They have specially designed controllers that let you control how the heater functions.
