The Eberspacher Hydronic 3 D5E CS (HS3) is a third-generation, fuel-powered water heater delivering 5 kW of heating power. It's ideal for passenger cars and transporters, designed to heat the vehicle’s interior and engine, as well as defrost windows. Its compact design is perfect for tight installation spaces, with the water pump and fuel metering pump installed separately. The fuel can be sourced directly from the return line using the admission-pressure-resistant metering pump, eliminating the need for a separate fuel tank extractor, which greatly reduces installation time.
The Eberspacher Airtronic S3 D2L 12V offers optimal fuel efficiency, multiple operating modes, and high safety standards. This third-generation, fuel-powered air heater provides between 0.85 kW and 2.2 kW of heating power, making it perfect for heating driver cabs in trucks, vans, motorhomes, minibuses, and even yachts. Certified for installation in passenger areas and near hazardous materials, it provides independent heating without relying on the vehicle's engine.
Both the water and air heater systems are genuine Eberspacher products and come with a 36-month warranty.
This dual system offers both hot air and hot water via a quick-warming coolant circuit. The water heater produces hot water within the unit, transferred through an indirect plate heat exchanger (or calorifier) that separates fresh water from the coolant, providing two independent circuits. A thermostatic mixer valve regulates water temperature, ensuring hot water is available within 5-10 minutes.
Once activated, the HS3 water heater draws fuel from the vehicle and heats the coolant through its dedicated heat exchanger. The heated coolant circulates through the system, warming either the freshwater tank or a heat exchanger plate to provide hot water for activities such as washing hands or showering, much like a domestic central heating system. This process ensures fast and efficient heating. The air heater, managed via the same controller, lets you select your preferred air temperature, and the system will maintain it automatically.
