[C320-list] Cabin Heat

[Magnuson's Time A Weigh]

Has anyone considered splicing into the heat exchanger coolant loop between 
the engine and the water heater, with an automotive type heater core and a 
12 volt fan to generate cabin heat while under way?  If a circulating pump 
were added, could it also generate cabin heat from the water tank heater 
while on shore power.  It seems like it could be mounted behind the sink 
cabinet drawers.   A three way valve could cut it out of the loop when it is 
not required.  Comments?
