THE REVOLUTIONARY ESPAR HYDRONIC S3 D4E
This diesel water heater uses cutting-edge technologies to provide a 14,665 BTU output while staying fuel efficient. The D4E is capable of reaching a record altitude of 3,000 meters (9,900 feet) when combined with the EasyStart Pro controller.
This heater operates significantly quieter thanks to the brushless fan and upgraded pump. As a result of the internal upgrades, the lifecycle is also increased to 5,000 hours.
CENTRAL HEATING IN YOUR VAN OR RV
Once activated, the Espar D4E heater will use the vehicle’s own fuel in a combustion process to heat the coolant via a heat exchanger inside the Hydronic Unit.
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 Espar air and water heater is self-regulating and operates in a similar way to a domestic central heating system.
COMPLETE WATER SYSTEM CUSTOM-BUILT FOR YOU
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 preheat the engine, as well as heat air and floors.
If you require extra features, custom kits can be built on demand.
