On my Berk, I seem to recall that the battery draw goes up by about 5 or 7 amps when I turn on the Tank Heat Switch. If you have a 400 amp hour battery setup, count on 200 amp hours of practical usage.
The more important issue for me is that the Tank Heater is basically useless for warming up the water in the tank. You've got less than 100 Watts to heat a tank with about 80 gallons of water. Now, my problem may be that I am usually getting cold mountain water in the Fall and Spring, so tap water is quite cold.
One solution that I have developed, but not fully tested, is to connect a hot water line to the tank fill. Since the Berk has a water manifold bay, it just takes a spare fitting to get hot water and a short hose to connect it to the tank fill. I can run this setup for a while with the bay door closed.
Another solution is to put an interior car heater in the bay that holds the tanks. They pull 800 to 1000 watts. I haven't tested this extensively, but it does require shore power or a generator to be running. I'm planning to install an extra plug in my basement, under the kitchen, so that I can run a power cord to the water bay next door. This will let me run the water heater all night.
BTW, if you are camping in the cold, you should fill your water tank and then disconnect and drain the fill hose. Otherwise you risk freezing your hose, and, worse, the connection at the source. This does let you use a tank heater or other setup to bring the water to a reasonable temperature.
And, I agree with the earlier poster that camping in cool weather goes through a lot of propane. The furnace uses far more propane than our stove, BBQ and hot water heater. A week would probably be about right, as he says, assuming that you have a large built-in propane tank.
