Espar B4L Airtronic M3 gasoline heater kit for van conversion 12V with Easystart Pro
The Espar B2L S3 is a compact 12V gasoline heater perfect for small to mid-size van conversions. It delivers 2 kW of efficient, dry heat and is ideal for 4-season travel.
Why it Stands Out:
- Produces 2 kW (~6,800 BTU) of clean, dry heat—well-suited for lightweight vans and mobile setups.
- Compact and lightweight (~2.5 kg; ~309 × 115 × 122 mm)—fits easily under a passenger seat
- Includes integrated altitude sensor, supporting automatic operation up to ~4,000 m (13,000 ft)
- Runs smoothly in extremely cold environments (down to –46 °C / –50 °F)
- Ultra‑quiet thanks to a brushless fan and dampened fuel pump; stepless blower ensures smooth temperature control
- Long-lasting: brushless motor rated for up to 5,000 hours of use
Features:
- 2 kW of heat – ideal for 4-season vanlife
- Runs on gasoline – taps into your van’s fuel tank
- Quiet operation – updated fan and fuel pump compared to the Eberspacher Airtronic M2 B4L
- High altitude ready – works up to 4,000 m (13,000 ft)
- Low fuel + power use – efficient all around
- Includes EasyStart Pro controller – included for full control
- Quiet operation
- Easy to install – complete kit included
A great choice for compact builds needing efficient, quiet, all-season heat.
