    Everything came from HeatSo in good shape, super FAST, and install was super easy. Recommend this product to anyone needing efficient, dry heat!

    Easy to instal

    Posted by Marcelo on 19th Nov 2019

    I installed this air heater in my 2017 Sprinter Van, I found all the parts I needed in the kit. It was easy and it is working fine.

    Great but needs extra parts and $$s to be fully usable.

    Posted by Jeremy Meigs on 12th Aug 2019

    First, HEATSO customer support was excellent and the product is amazing once you get it set up and properly wired/working.

    Issues I had are:

    * You need the High Altitude kit if you ever go near the mountains... which is where you usually need the heater! + ~$400 if not on sale...

    * The temperature sensor that comes with the Remote + unit is not usable as a thermostat. It just lets you know the temp. but won't shut off the heater at the desired temp. + ~$50...

    * The Molex Micro-J connectors are a pain to use, small and not initially crimped (which technically needs a tool to properly crimp and another tool to remove if you make a mistake putting them in the housings).

    great, reliable heater. good customer service

    Posted by kilohotel on 2nd Oct 2018

    You will receive A LOT of extra parts. Don't be alarmed. Install and wiring is actually pretty simple if you keep in mind that not all parts and wires will be used. The only thing I find frustrating is that there is no reducer hose barb to make the fuel line installation in a newer Sprinter easy. I was unable to find the part locally and had to order online. the only part you should need for a newer sprinter install(one with the fuel tank already tapped) is a 1/4" to 3/16" hose barb to transition from the sprinter fuel line to the Espar fuel line.

    D2 Heater kit

    Posted by Scott H on 5th Sep 2018

    I installed a D2 heater in my 2017 Mercedes Sprinter. I chose to install the heater on the driver's side floor, just in front of the rear wheel well. I think this location is much preferred over the passenger seat installation location. The diesel tap from the tank is on the drivers side and it makes in convenient. It is also preferred to be able to have the exhaust on the driver side away from the main cargo door. I was able to install on my own, but I found it a bit challenging. Limited directions are provided and the wiring diagram is a bit intimidating at first. Improved directions would be helpful. I have used the heater for nearly a year and so far so good.

    So Happy!

    Posted by Aaron on 20th Nov 2017

    What an amazing heater! Installed in a 170" MB Sprinter and it easily heats the van. Skip the mounting bracket-- I had to cut it down as it is too large to use under the passenger seat. Just use scrap metal as your mounting bracket. Heatso service is 1st class and I received my D2 in Colorado in under two days. Your eyes will glaze over at the wiring diagram the first time you look at it, but after a few YouTube videos, it's actually pretty easy.

    perfect for crane cab on Manitowoc M250

    Posted by Frank on 28th Oct 2015

    Very nice unit bought the tank also. Used in a crane cab and its plenty big enough actually it will run you out of it if you leave it on high for long. Easy install could use a better wiring schematic but still no problem. Very satisfied
