OZK Customs + Espar AM3 B4L Airtronic gas 4 kW 12v Heater (Transit)

Built with similar features to their S2 D2L 12V Diesel heater for the Sprinter, the AM3 B4L 12V Gasoline Heater is the perfect companion to the Ford Transit. Designed to offer you comfort in the harshest of environments, this brilliant, compact heater provides consistent performance up to 18,000 feet in altitude, and in temperatures down to -50.

This powerful 4.4 kW heater provides an impressive 13,650 BTU’s of total heat output – so you can warm you van up FAST after even the coldest days outside. And it’s worth mentioning again that the heater functions effectively down to temps of -50, so if you are, we assume, unfortunate enough to encounter a day that bitter on your winter adventures, you can hang out comfortably in your van while you wait for it to not be cold enough to freeze your skin.

Designed with the knowledge that altitude and temperature often go hand-in-hand, this heater is also engineered to produce heat up to altitudes of 18,000 feet with automatic altitude adjustment already built in. The impressive built-in altitude sensor of this gasoline heater means unless you are planning to literally off-road to the top of Denali, you can be toasty in your Transit adventure van on top of the highest mountain in the lower 48 states (you know, if the roads were open that high, in the winter.)

Designed to be a plug-and-play system with a same-line fuel system, this efficient heater runs on your Transit van’s gas tank. This means it does not pull valuable power from your battery pack when you are off grid! And the upgraded combustion chamber allows it to be one of the most efficient and environmentally friendly heaters on the market for the Mercedes Sprinter Adventure Van.

It comes with a built-in temperature sensor and EasyStart Pro controller, so you fine-tuned temperature adjustment and precise control of your heat setting. The kit also offers flexible installation options with an adaptable ducting system that we can set-up to work effectively with your Transit’s interior layout. You can select the types of outlets and grills you want installed to meet your needs and provide optimized heat distribution. The new brushless fan and integrated blower system mean you always get consistent and quiet heating no matter the conditions.

With precise temperature control, market-leading German engineering, and impressive but efficient heat production capabilities, this is the heater you want in your Transit adventure van to provide a comfortable, no-maintenance experience so you can enjoy a climate-controlled environment in the coldest situations.
