Eberspacher Hydronic 3 D5E (HS3) Overview
The Eberspacher Hydronic 3 D5E (HS3) is a third-generation, fuel-powered water heater with a 5 kW heating capacity, designed for passenger cars and transporters. This heater efficiently warms the vehicle’s interior, engine, and defrosts windows. Its compact design allows for installation in tight spaces, with the water pump and fuel metering pump installed separately. The fuel is sourced directly from the return line using an admission-pressure-resistant metering pump, eliminating the need for a separate fuel tank extractor and significantly reducing installation time.

Warranty and Reliability
This is an authentic Eberspacher heater, covered by a 36-month warranty.
Advanced Heating System
The compact and reliable Hydronic D5E 5 kW water heater features an independent, self-contained coolant system that rapidly provides hot water and air. A small coolant circuit is utilized, offering quick warm-up times, producing hot water within the heater unit. This water then heats a 10-liter hot water storage tank, which can also be heated via a 230-240V mains supply. A thermostatic mixer valve manages the hot water temperature to the taps, ensuring controlled temperatures for showers or taps, with hot water ready in approximately 5-10 minutes.
Installation and Functionality
The D5E CS model is designed for easy exterior mounting on the vehicle, while the hot water storage tank offers flexible installation options, allowing placement either inside or outside the vehicle. For optimal fit, be sure to check the dimensions carefully. Blower units are installed in areas requiring the most heat, such as living spaces and the rear. The automatic blower control switch, equipped with an external temperature sensor, regulates room temperature by adjusting fan speed. The fans operate more quickly as the temperature difference increases and slow down as the room temperature approaches the set level.
Operational Efficiency
Once activated, the HS3 Water heater uses the vehicle’s fuel in a combustion process to heat the coolant through a heat exchanger. The heated coolant circulates through the heating circuit, passing through the freshwater storage tank and blower heaters, propelled by an integrated water pump. The Eberspacher Hydronic 3 D5E unit is self-regulating, functioning similarly to a domestic central heating system.
