If you have a hot water system that uses the heat from the engine
to heat fresh water, you can tap a loop into that with a simple on-off valve that passes some of the engine coolant
through a hydronic heater (see Heater Craft Auxiliary Cabin Heater
) with a samll recirculating pump in the circuit to keep things moving when the engine isn't running. Then, simply insert the Blue Seas systems "ACR" previously mentioned in your power system to dump juice from the wind
turbine to a heating eliment in your hot water heater. When you need heat, open the valve in the coolant
line and turn the heater fan on, with a tap from the heater fan switch that also actuates the recirculation pump. The coolant will pick-up the heat from the hot water tank and transfer it to the heater. We've got one of these on our boat (albeit without the heating from dumping the excess power from the wind turbine) and, it works great.
