Eberspächer says its new Hydronic M II yacht heater offers substantial benefits over previous models, including a doubling in service life and a decrease in the time to reach maximum heat output.

Eberspächer’s Hydronic M II water heaters feature double the service life, faster heating performance, and “extremely quiet operation,” compared to previous models, says the company.

The heaters—available in 8-, 10-, and 12-kW models—are suitable for medium-sized motor yachts, up to about 12 m (39 ft) in length. Depending on the version, yachts 55, 70, or 85 m3 (74, 94, and 114 yd3) in volume can be heated “from spring through to autumn.”

The Hydronic M II reaches its maximum heat output in just two-thirds of the time taken by conventional yacht heaters. Another advantage is that the range’s service life has been doubled from 3000 h to 6000 h. This increase was achieved via a new design for the combustion chamber, as well as new combustion fan motors and water pump.

Diesel fuel required for heating is drawn directly from the onboard fuel tank. The 8-kW model consumes a maximum of 0.9 L/h (0.2 gal/h) and can also be operated with up to 100% biodiesel. In addition to the cabin, the water heater can also heat the service water in the boiler or be connected to the engine. The small, space-saving pipes are a general advantage of this type of heater.

Some controls offer a preprogramming facility to ensure that the cabin is always warm when the captain steps on board. The programmable remote control also displays the heater’s operating status and the cabin temperature from as much as 1000 m (3280 ft) away. If operators want to switch the onboard heater on or off while at home or en route, they only need to use the system’s Calltronic system via a landline or mobile phone.
