Whale Seaward 3-Gallon Side-Exchange Water Heater

Whale Electric Water Heaters are built from the highest quality materials available and designed specifically to withstand harsh marine conditions, rather than adapted from a residential design.

At just 14 lbs, this 11-liter (3 US gal) model is Whale's lightest water heater, a real consideration on a smaller boat where every pound of added weight matters. The white epoxy coating blends in with existing engine room equipment while adding corrosion resistance and keeping weight down.

It uses a side-mounted combination electric and heat exchanger element, and features include hold-down brackets welded to the inner tank, double-wall heat exchangers, an integrated pressure relief valve, and an included temperature and pressure drain tube. Runs on 120V at 1500W. Explore more water heaters.
