Whale Electric Water Heaters includes model with the very latest technology. All heaters are manufactured from the highest quality materials and designed to specifically withstand harsh marine conditions.


The Marine Galvanized Steel Cover offers corrosion resistance at an affordable price. This material weighs more than the other case options but is made from a strong and robust material
