Eberspacher Hydronic S3 D4 12V Kit

The Eberspacher Hydronic S3 D4 heater kit (12V) is the latest model and can be used for narrowboats up to 60'.

If you are unsure about the sizing, please do not hesitate to contact us.

This kit includes the heater unit, fuel pump, circulation pump, mounting brackets, twin port header tank, silenced exhaust with lagging, skin fitting, control panel with diagnostics and a programmable 7 day timer, wiring loom, and all necessary fittings.

The S3 heater has a brushless variable speed combustion air motor, which not only improves efficiency but also extends its service life. The new fuel pump and circulation pump are now mounted externally, leading to a reduction in noise output and increased efficiency.

Additionally, this version is equipped with the 'Easy Start Pro' digital control panel, which features a back-lit LCD display and one-touch control button for easy navigation and access to options such as the programmable timer and diagnostics.

This heater model is suitable for use with existing S+ diagnostic testers, and can replace older S1 Hydronic heaters if new control panel, wiring, circulation pump, and fuel pump are utilized.

Downloadable data sheets containing specifications and installation guidance are available.
