Yes there is an easy way. My setup with a Hurricane II is identical to what you want to do. Put a heat exchanger into a valved coolant loop off the engine with the diesel heater loop on the other side of the heat exchanger. The valves would be open when you're cruising and off when you're at anchor or the dock.

A decent heater install guy should know all about this setup.
