Description

EBERSPACHER - Hydronic S3 D4E 12V water heater

The Hydronic S3 D4E 12V water heater is suitable for sailboats and motorboats up to 10 meters in length, and for heating spaces averaging 10 m³. Coupled with a conventional-water heater, you can also heat the water in your on-board tap or shower, so you can enjoy hot water in all conditions.

It features an optimized burner and advanced electronic management to minimize fuel consumption while maximizing heat output.


fonctionnement chauffage à eau S3 D5E

HOW A WATER HEATER WORKS

Combustion air from the environment and fuel from the tank are mixed and burned in the combustion chamber to heat a coolant.

The heat exchanger then transfers the thermal energy to the heating circuit to warm the interior of your boat.

The heater operates independently of your engine, so you can warm up your cabin without having to start your engine. This is ideal when your boat is docked, as well as for long periods of time.


SAFETY AND COMPLIANCE

Eberspächer is committed to safety. The Hydronic S3 D4E 12V model is equipped with multiple safety features, including overheating sensors, flame detectors, and automatic cut-off mechanisms in the event of malfunction.

The heater complies with international standards and regulations for on-board heater safety, and meets the requirements of the European Union, CE and other regulatory bodies.
