Espar Heater Installation

Installing an Espar D2 diesel heater in a 2014 Sprinter van

The Espar diesel heater I installed does what it’s made to do: it blows very hot air into my van and keeps things toasty and cozy. The Espar heater installation instructions, on the other hand, are frustrating and intimidating. Having reached the happy and unexpected outcome of a working heater, I decided to document my process to help others with this daunting task. I’m a neuroscientist, not an electrical engineer, but I do have heat in my van, so take that as you will.
