Eberspacher Hydronic D5E 12V Diesel RV Kit  for Water, Air, and Floor Heating

An upgraded version of the popular D5S Hydronic kit, the new Espar Hydronic D5E RV kit was designed with optimal performance and the highest quality standards in mind. A proven heater on the market from one of the most reputable and reliable German manufacturers, this model comes with a brushless fan, a quieter pump and an integrated temperature and altitude sensor. The heater, known as the Eberspacher Hydronic D5E in Europe, uses your vehicle’s own fuel to heat air, water and even floors. Typically bundled with the modern EasyStart Pro controller, this kit can be connected to a variety of water and air exchangers. The kit comes with all the parts needed for installation, including mounting brackets, clamps and screws. We can also offer you a custom build – get in touch today to learn more.

Key features of the Espar Hydronic D5E 12V RV kit:

  • As a third-generation hydronic heater of the CS variety, the D5E is much more versatile than its predecessors and is being constantly updated.

  • Due to its compact size, the heater can be fitted either in the vehicle engine compartment or internally.

  • The maximum heat output of this model is 5 kW / 17,000 BTU. 

  • The kit ships together with an 4.3 kW Kalori air heater, which is mounted internally. The Kalori unit can be connected to different areas via ducting adapters.

  • The kit includes a water plate exchanger for heating water that connects to the tap or shower and is mounted internally.

  • The Espar Hydronic D5E can be operated independently or connected to the vehicle’s own engine coolant system.

  • When used together with the EasyStart Pro controller, the kit can operate at altitudes as high as 3,000 meters / 9,900 feet. Without the controller, the maximal operational altitude is still relatively high at 1,500 meters / 4,900 feet.

  • The kit is equipped with a brushless motor resulting in quieter output and higher comfort levels.

  • The brushless motor also means the lifecycle is increased from 3,000 to 5,000 hours.

  • Thanks to the heater’s stepless system, fan speed is adjusted according to the temperature set. This maximizes efficiency and improves comfort. 

  • An improved fuel pump piston provides the additional benefit of reducing the clicking sound, which can be rather annoying in other models.

  • The EasyStart controller provides an automatic temperature control option (Thermostatic function) due to its integrated temperature sensor.

  • The unit works with both CAN and S++ communication protocols.

User benefits of the Espar Hydronic D5E 12V RV kit

This diesel heater RV kit can be used for a variety of purposes, including heating up water, air, car floors, radiators and the engine. Unlike some other diesel RV heaters, this unit is extremely easy to install, in part due to its compact size. Due to several features including a brushless motor, the model is quieter and does not interfere with your sleep, a problem users of older units commonly face.

One way to save both power and fuel is using residual heating with a switched-off engine. This feature allows the system to run for as long as the coolant temperature does not drop below the threshold set by the user. The kit can operate with different water and air heat exchangers. It can also run an independent heating loop with multiple accessories connected to it.

The shipped kit provides a complete domestic water heating system that can be used for showers and taps. In addition, the universal kit can be used to pre-heat the engine, as well as heat air and floors. If you require extra features, custom kits can be built on demand. Contact us for more information.

    Adding Diesel Hydronic to an Off-road Caravan

    Posted by Chris Lloyd on 16th Mar 2021

    Ordered this in Feb 2021 I believe and installed by mid march. This kit had everything I needed to add diesel hydronic heat + hot water to my RV trailer/caravan. Very happy with the end result. This kit requires a fair biit of effort to install. There are quite a few parts to the system. The electrical connections between the espar harness and heat exchanger / fan were not immediately apparent. Needed some electrical skills to figure out how they interfaced. I did not contact support once though so maybe that's on me. Need to also know how to find and clear Espar error codes. A few helpful links included with the kit would have gone a long way in saving time on my end. But the end result I have wonderful heat at under 40db noise level when fan is on low.

    Posted by Chris Nielsen on 18th Nov 2020

    I've installed the DS5 in other vans and am hoping your instructions for the D5E has better schematics for integrating the controls with the heater. Otherwise the heater works great!! Just need better instructions for the layman...........thanks, Chris

    Perfect set up for my build

    Posted by Sterner on 1st Jul 2020

    I was not sure about this kit but it all turned out to be just perfect! Got hot water, air heating, and by installing a bypass valve my van now has floor heating during the colder day and stainless steel towel rail in a shower whenever I am in the shower! This RV kit is extremely impressive! Thanks, J. Sterner
