Espar / Eberspacher Hydronic S3 D5E CS 12V water / engine heater

Espar Hydronic S3 D5E Water Heater D5-H3-CS 

An upgraded version of the tried and tested D5S diesel heater, the new Espar S3 D5E was designed with the highest quality and performance standards in mind. This third-generation hydronic heater is popular with users for its compact size, silent brushless motor, and improved fuel pump piston. These and other features make it the quietest heater in this category. The unit also boasts a unique residual heating system that allows the heater to operate after the engine is shut off.  The fully installation kit from Espar is the definition of plug & play, with no extra parts required. 

Latest upgraded unit 2020 version.

User benefits of the Espar Hydronic D5E Water Heater

Being smaller than previous Espar coolant heaters, this compact heater is extremely easy to install. Due to its size, it can be installed in a range of vehicle and vessel applications, and can also be mounted externally. The kit comes complete with mounting brackets, clamps and screws, and can be installed without any additional parts. Convenience aside, the Espar S3 D5E CS is one of the quietest units on the market, partially due to its integrated air exhaust and intake silencer. It is also easy to control and run diagnostics for faults and errors. This upgraded heater features a brushless fan and an improved water pump, which increase the lifecycle of the heater from 3,000 to 5,000 hours. Providing the benefit of residual heating, the Espar S3 D5E CS can help save both power and fuel. What’s more, this model can run an independent heating loop, with multiple accessories connected to it.

The model is versatile and can be connected to a variety of water and air exchangers. It can also use either its internal temperature sensor or an external controller. Because the unit is compatible with CAN, LIN and S+ system communication protocols, you can connect an earlier generation controller with no hassle. However, to get the best out of your Espar S3 D5E CS, we recommend bundling it with the EasyStart Pro controller.
