Eberspacher Hydroplate Hydronic HS3 D5E Diesel Water Heater
Eberspächer Hydronic HS3 D5E Hydroplate
The Hydroplate system is designed to provide efficient water heating by tapping directly into your vehicle’s existing diesel tank or utilising a designated external fuel tank.
Running on a low-amp 12V electrical draw, the unit achieves operational temperature quickly, making hot water available for washing or showering in approximately 10 to 15 minutes.
The system provides continuous hot water tailored to typical domestic caravan water pumps (averaging 6–11 litres per minute).
While optimal for short bursts of up to 3 minutes, flow duration can extend depending on your required temperature settings.
For total climate control, the Hydroplate features an optional air heating matrix add-on, transforming the system into a complete, space-saving hot water and cabin air heating solution for true off-grid living.
Features:
Fuel Source Flexibility: Operates efficiently by sourcing diesel directly from the vehicle’s main tank or a separate dedicated fuel tank.
Ultra-Low Electrical Consumption: Built with a low-draw 12V operation to preserve your house battery capacity while camping off-grid.
Rapid Warm-Up Time: Reaches standard operational temperatures to supply hot water in just 10–15 minutes.
Dual-Purpose Upgrade: Can be seamlessly paired with an optional 2.5 kW fan-coil air matrix kit to provide cabin air heating alongside domestic hot water.
Continuous-Flow Technology: Designed to work efficiently with standard 6–11 L/min domestic water pumps.
