New generation Eberspacher Hydronic S3 D5 heater kit (12V). Suitable for narrowboats up to 70' and most wide-beam narrowboats up to 60' (please contact us if you are unsure about heater sizing). Includes heater unit, fuel pump, circulation pump, mounting brackets, twin port header tank, silenced exhaust with lagging, skin fitting, control panel with diagnostics and programmable 7 day timer, wiring loom and associated fittings. The S3 heater is fitted with a brushless variable speed combustion air motor which improves efficiency and service life. The new fuel pump and circulation pump are mounted externally to the heater, and design improvements have resulted in less noise output, greater efficiency and make the heater easier to service. The 'Easy Start Pro' digital control panel incorporates a, back-lit LCD display and one-touch control button to select options from the menu, including the programmable timer and diagnostics. This version of heater is compatible with existing S+ diagnostic testers, and can only replace the older S1 Hydronic heaters if new mount brackets, control panel, wiring, circulation pump and fuel pump are used. Data sheets including specifications and installation advice are available to download. Please contact us for more information.
