The water heater system is ideally suited to large boats or boats which are too restrictive for ducting.  It comprises of a small diesel-fired heater with a water jacket around the heat exchanger.  The cold water is heated up by the heater and is pumped around the boat via plastic plumbing (no heat work required) to either fan matrixes (like the heater in a car) or to radiators (as in the home).

This system can also be plumbed into a calorifier (hot water tank) to give you hot water without shore power or the engine heating and it can be plumbed into the engine as a pre-heat.  As with the hot air heaters, these are also very compact and can normally be installed out of sight.

We are familiar with the ranges of water heaters from of the following manufacturers:
