Kuuma 11810 - 6 Gallon Water Heater - 120V

The Kuuma 11810 6 Gallon Water Heater (120V) is a marine-grade electrical water heating solution designed for boats, RVs, and compact installations where reliable hot water is essential. Built from corrosion-resistant aluminum, this 120V water heater combines electrical heating with an integrated heat exchanger, allowing dual-mode operation for consistent hot water supply whether docked or underway. The 6-gallon capacity delivers adequate hot water for washdowns, galley use, and shower applications aboard vessels where space and weight constraints demand efficient compact equipment.

Key specifications reflect marine-duty engineering: corrosion-resistant aluminum construction handles the saltwater and humidity environment where freshwater tanks deteriorate. Ignition-protected controls prevent electrical hazards in wet marine environments. The integrated heat exchanger allows the unit to capture waste heat from engine cooling systems, reducing electrical load during operation. Mounting tabs enable secure installation in confined engine compartments or locker spaces. Manual reset safety control provides a failsafe mechanism for overcondition shutoffs. At 22 pounds, the unit remains light enough for retrofit installations while maintaining thermal mass for consistent water temperature delivery.

This water heater suits weekend cruisers, fishing boat operators, and liveaboards who require reliable hot water without complex plumbing or high-capacity systems. The dual heating capability—electrical plus heat exchanger integration—eliminates the all-or-nothing approach of single-mode heaters, making it practical for extended trips where shore power may be limited. Replacement buyers upgrading corroded or failed units find this model a direct fit for existing 120V installations. The aluminum construction and marine-rated components ensure years of service in environments where standard residential water heaters fail within seasons.
