Espar D2 Diesel Heater Sprinter kit

Created based on the feedback and recommendations of lifetime van owners, the Espar D2 Sprinter Kit is the ideal heater kit for all Sprinter van models up to 2008. But the Espar D2 diesel heater is much more versatile than that, and can be used in lots of other applications. Ideal for travelling and camping at high altitudes, this 12V heater offers 4 output levels, and a convenient air ventilation mode. Its long flexible ducting means that it can be used to heat different areas of your van. Espar heaters are leaders in the market, so finding repair shops or parts is not a problem. This means that maintenance and repair is hassle free. 

Key features of the Espar D2 Heater Kit 

  • The Espar D2 is a 12V diesel heater that operates as a forced air heater.
  • It has a 2.2kW / 7500BTU heat output and offers 4 different heating levels - low, medium, high, and power (boost) - making it easy to achieve the heat level you want.
  • Comes complete with a separate standpipe to provide direct access to the tank’s fuel supply when no auxiliary tap is available. Additional fuel connectors can also be purchased separately. 
  • The Espar D2 diesel heater comes with an air ventilation mode for circulating cold air through the ducting system, making it perfect for cooling your van on hot nights
  • It is truly fuel efficient and economical. Benefit from fuel and power consumption as low as 0.10 l/h for medium heat, 0.15l/h for high heat and 0.23l/h, and 0.28l/h for maximum heat. 
  • The Espar D2 Sprinter Kit is easy to install and maintain, and comes with all the necessary parts for installation (see full contents of the kit below).
  • It is compact in size, meaning that it can be installed under the passenger seat, in small compartments, or even externally. (external mounting accessories are required)
  • It uses an integrated internal temperature sensor to monitor temperature. An additional external temperature sensor is available which can be placed in locations like your sleeping area and provides higher accuracy and comfort level.
  • The Espar Sprinter Diesel Heater  is perfect for operating at high altitudes. It can handle altitudes of up to 2,200 meters / 7200 feet, and with an additional High Altitude Kit, it can be used even higher up. 
  • The Espar D2 Sprinter Diesel Heater uses CAN, LIN and S+ system communication protocols, meaning it can also be used with early generation controllers. 

User benefits of the Espar D2 Sprinter Kit 

The Espar D2 Sprinter kit is the most reliable 12V heater on the market. Designed with Sprinter drivers in mind, it has everything you might need and then some. It comes with additional fuel system accessories for pre-2008 Sprinter models that allow you to connect the heater straight to your fuel tank even if you don’t have an auxiliary tap. And because it is more compact than other high output 12V heaters, it can be mounted under the passenger seat.  And when it comes to temperature control, you’ll find it offers the accuracy you expect from Espar diesel heaters. And for even more temperature control, you can buy an external temperature unit for your sprinter diesel heater that is able to override the internally mounted temperature sensor. The Espar D2 diesel heater Sprinter kit comes installed with  4 heating levels – low, medium, high, power, as well as an air ventilation mode that will help you cool down your van. As with a lot of espar diesel heaters, the D2 Espar heater unit also comes with enhanced on screen diagnostics, allowing you to detect any issues as they appear.

What distinguishes the Espar D2 Heater kit from other sprinter diesel heaters in the market is the fact that it can be used at high altitudes. Espar’s one of a kind altitude adjustment feature allows it to function at 2200 meters, about 700 meters higher than its competitors. Not only that, if you’d like to use your Espar D2 higher than that, you can buy the special High Altitude kit.  What’s more, if you’d like to customise your heater, the Espar Sprinter Diesel Heater uses LIN, CAN and S+ technologies, allowing you more freedom for custom control builds.

    Great Product

    Posted by Carey F on 13th Mar 2021

    This is a reliable heater that has served me well through the winter. Installation is complex at best but all items necessary came in the kit. Very helpful. Wiring installation need to access online resources for the correct set up.

    A surprise for the money

    I typically do not write reviews but this heater really deserves my time - super happy with the product and delivery time. I was going to post some pictures, but couldn't find a way to do so?
