This is the label on Ibis water heater. It is a Force10 406011 which is a 6 gallon 115V 1500W heater with front heat exchanger connections. The prior owner used it only with engine heating, running the diesel in the morning to heat water for a shower, charge batteries and freeze the refrigerator cold plate.

This water heater has been removed and will be replaced with two 3 gallon 12V 300W water heaters, one for galley and the other for vanity and shower. Both will be mounted in the cabin.
