Yes, if you read the 38 Eight shop manual as an example there is a discussion on the combined use of the shutter thermostat and a water outlet stat for winter use when equipped with a hot water heater.
But in the earlier years when the thermostats (shutter) were limited to 160 degrees because of the prevelant use of alcohol antifreeze, hot water heaters weren't very efficient in colder weather, thus the popularity of the hot air heat exchangers like the Kelch which had considerable popularity on the higher-end cars.
Along those lines you might find the attached article interesting (at least I hope so).
