Apart from all interior rooms of the boat, Eberspacher water heaters also heat the domestic water and in addition ensure that the engine is pre-heated optimally.

The Hydronic 4 is a miniature water heating system offering variable heat output. Incorporates automatic heat regulation, minimising fuel and power consumption.

How the Eberspacher water heater works

The water heated to 80°C is pumped through the piping and the radiators connected to it. Since the marine diesel and the generator generate heat during the journey, these units should also be included in the heating system to use the waste heat. Installation of an expansion tank, a pressure gauge and a safety valve is indispensable.

The most important advantages of the Hydronic summarised
