Key features of the Espar B4L gasoline heater

• The Espar Airtronic M2 B4L is the most powerful petrol / gasoline heater available, offering 4kW / 13650 BTU maximum heat output. This power, combined with the B4L’s advanced features and engineering, makes it one of the most popular petrol / gasoline heaters on the market.

• The Espar B4L is engineered to operate in extreme conditions and high altitudes. It can operate in temperatures as low as -46°C / – 50°F and at altitudes of up to 9,900 feet. This is enabled thanks to its integrated altitude sensor, and unlike earlier models there is no additional wiring or installation required for high altitude operation.

• Controlling the heater is simple because it has an integrated temperature sensor and EasyStart Pro controller. The Espar B4L’s stepless blower system enables optimized heating control and maximizes performance efficiency.

• The stepless blower system also ensures quieter performance compared to previous models, while the improved fuel pump piston reduces clicking noise. The Espar B4L also sports a brushless fan which helps to further reduce noise.

• The Espar B4L is highly versatile when it comes to installation. Its adaptable ducting system, which can go up to 15 meters / 49ft in length, features outlets of either 60mm, 75mm or 90mm. Ducting outlets are closeable and can have different degree grilles and outlet types, plus the number of outlets can be varied based on the complexity of the ducting system.

• The Espar B4L is easier to install than previous models. It features plug and play  installation which requires fewer tools and no cable crimping, enabling DIY installation.

• The heater’s fuel system plugs directly into your vehicle’s fuel system or tank with a standpipe (Optional) or via an auxiliary tap (if your vehicle manufacturer offers one). Installation of the fuel system has been simplified for this model, with the same line used for the whole installation.

• The Espar B4L is compatible with all 3 communication protocol technologies used by Espar – CAN, LIN and S+. This means you can use your earlier generation controller with the Espar B4L

• Custom installation kits can be arranged based on requirements of your vehicle (get in touch with the Heatso team to discuss your specific needs).

• The brushless fan ensures the Espar B4L has a long operating life, increasing service time from 3k hours (on previous models) up to 5k hours. And if there are any issues, the its new controller communication system allows more accurate on-screen fault diagnostics.

User benefits of the Espar B4L gasoline heater kit

There are many reasons why the 12V gasoline heater is so popular as a van heater. Its powerful heat output (4kW / 13650 BTU max heat output) is a clear advantage, as is the ability to use it in extreme conditions, including at high altitudes and in low temperatures. This heater also offers strong fuel efficiency, and is a cost-effective option especially for long-term usage.

If you are looking for a gasoline heater you can install yourself, the B4L is a smart option. It’s compatible with various petrol / gasoline vehicles, and is especially popular with Ford Transit and RAM Promaster owners.
