ESPAR / EBERSPACHER AIRTRONIC B4L M2
On of the better purchases I have made for my Vanagon Westfalia! Toasty warm on cold nights. Highly recommended.

Works great in Ford Transit
I installed the Airtronic B4L two weeks ago and we have been on two overnight trips and it is perfect! I turn it on or set it to run all night and it heats up fast and it is quiet. We didn't notice any loud clicking sounds from the pump and the air blower is smooth and creates a nice white noise for sleeping. Plenty of BTU power to heat the van.

Great heater, even at 9,000 ft!
This heater works great for a van like a Promaster. It has now kept us warm for many nights running for 8 hours or more at a time, even at elevations of 9,000 ft. I give the heater five stars. However, it did take some time for heatso.com to get me the correct heater. They accidentally shipped the diesel model of this heater. After taking weeks to clear customs, I had to send the heater back so they could ship the correct one. Quite the problem when shipping international and resulted in about 6 weeks or more from when I placed the order, until I received the correct unit. I also swapped out mounting plates for the flat mounting plate, but have not received a refund for that difference.

Highly recommend
The install wasn't too difficult, the installation kit came with everything I needed (and more) and the heater is working well so far! The instructions aren't the best but if you stare at it long enough you'll figure it out haha..

ECU ECU ECU
This is the latest espar 14k btu petrol heater and the manufacturer had huge problems with the control units so I suggest you get a unit from later batches. I ordered this kit as soon as it was introduced so it had that shitty ECU - took some time to sort out but heatso were really helpful and I now have the new type ECU which seems to be working fine. Overall it is a good heater just make sure you get the latest model with latest ECU version!!! The merchant is fine - very friendly and helpful guys.
