The small size of this water heater opens up a range of installation possibilities.

Weighing just 14 pounds and with its small size, this water heater is a good choice for installation on smaller boats, for example as a source of hot water for a deck shower. It's small enough to fit under seating, or other places where larger capacity water heaters won't fit. Use of a magnesium anode is strongly recommended to prevent galvanic corrosion and extend tank life.
