Whale Seaward 3-Gallon Electric-Only 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.

This electric-only version skips the heat exchanger for a simpler installation, and it includes hold-down brackets welded to the inner tank, double-wall construction, an integrated pressure relief valve, and an included temperature and pressure drain tube. Available in the Americas only, running on 120V at 1500W. Check out the rest of our water heaters.
