ESPAR AIRTRONIC AS3 B2L 12V AIR HEATER WITH INSTALLATION KIT

The Espar B2L gasoline heater is a brand new 2kW gasoline heater from Espar. The B2L is the smallest 12V gasoline van heater and is suitable for use at high altitudes up to 13,120ft without a high altitude kit.

This heater can operate in temperatures as low as -46°C / -50°F, and it is designed for compatibility with a wide range of vehicles. The AS3 B2L's state-of-the-art performance, versatility, and efficiency makes it one of the best choices for gasoline powered vans and small trucks.  

FEATURES OF THE ESPAR AS3 B2L GASOLINE HEATER

Smart sensor-controlled starting sequence ensures efficient ignition with lower current draw.

Integrated altitude sensor for reliable operation up to 13,120 feet.

Optimized metering pump and improved brushless motor ensure silent and efficient performance.

New combustion chamber and dynamic heating control for improved fuel efficiency.

Smart sensor-controlled starting sequence ensures efficient ignition with lower current draw.

Integrated altitude sensor for reliable operation up to 9,800 feet.

Optimized metering pump and improved brushless motor ensure silent and efficient performance.

New combustion chamber and dynamic heating control for improved fuel efficiency.

INTRODUCING THE ESPAR B2L GASOLINE HEATER KIT

The Espar B2L gasoline heater kit is the latest addition to Espar's range of gasoline heaters. This 2kW gasoline heater kit is designed to be versatile and efficient, offering optimized heating control and high altitude operation capability without compromising on performance.

The 2kW gasoline heater market used to be dominated by the Webasto Air Top 2000 STC, a long-time community favorite. Check out how the new AS3 B2L compares to the old classic in our 2kW gasoline heater showdown, and find out the pros and cons of both.

OPTIMIZED HEATING CONTROL WITH STEPLESS BLOWER SYSTEM

The Espar B2L features a novel stepless blower system that enables optimized heating control and maximizes performance efficiency. This system ensures quieter performance compared to previous models.

To make the heater less intrusive, the fuel pump piston has been dampened to reduce clicking noise. The brushless fan helps to further reduce noise and increase the operating life of the heater.

HIGH ALTITUDE OPERATION CAPABILITY

The Espar B2L is engineered to operate in extreme conditions and high altitudes of up to 13,120 feet. Its integrated altitude sensor means no additional wiring or installation is required for high-altitude operation. This feature sets the B2L apart from earlier models, making it a more versatile option for those who regularly travel at high altitudes.

EASY INSTALLATION AND COMPATIBILITY WITH A WIDE RANGE OF VEHICLES

Installation of the Espar B2L gasoline heater kit have been made simple with plug-and-play installation, requiring fewer tools. And the Espar Airtronic AS3 B2L has a hidden benefit – it's perfectly compatible with the B4L peripherals.

The B4/B4L used to be the smallest gasoline heater from Espar, so many van lifers opted for 4kW even if they didn't need so much heat. If you have an old B4, upgrading to the new B2L takes just a few hours. It's as easy as replacing a single fuel metering pump and popping in the heater.
