    Fast Shipping - Great Product

    Posted by Mike on 15th Dec 2019

    Shipping was unbelievably fast. Shipped from UK to US in 2 days... For FREE! I was blown away. Box was a little beatup, but everything arrived intact. This is a great kit for Sprinter/Van conversion. It has basically everything you need and some extras. I did end up getting a 5/16 to 1/8 hose barb fitting and some heat shield for the fuel line locally but other than that this kit was complete. Thanks Heatso!

    ESPAR AIRTRONIC S2 D2L 12V Heater Kit

    Posted by Carla Singleton on 11th Dec 2019

    The heater works great and we are very happy with the purchase. The only reason for four stars instead of five is that when the auto dealership was installing the heater they told us the fuel filter was not present. So between parts and labor it cost $100 to get a fuel filter installed.

    I can't express enough how happy I am with going with this model, because you can't get anything better at this price IMHO. Installation is pretty straightforward if you have some DIY skills and this kit really had all the bits we needed for our installation (just make sure you get the mounting plate). Fast shipping and really helpful customer service. happy!!!

    Best heater out there

    Posted by Allan Tone on 25th Nov 2019

    This is the heater we install in all our custom van builds. Dependable, quiet, and hot. Works at altitude too!!

    I installed this myself on a 2018 Sprinter van and found it all to be pretty straightforward. Plenty of videos online to provide tips specific to the Sprinter. Paired with the easy start pro timer and works great. I didn't need to purchase anything else to make it all work.
