Kuuma 11812 - 6 Gallon Water Heater - 120V

The Kuuma 11812 - 6 Gallon Water Heater - 120V is purpose-built for cruising anglers and boaters who demand reliable hot water at the dock or underway. Whether you're running a fishing charter, living aboard, or taking extended trips into remote waters, consistent hot water transforms the onboard experience from a luxury into a necessity. This compact yet robust water heater integrates seamlessly into existing marine plumbing systems and serves as an ideal replacement for aging units or new installations on modern vessels.

Built from corrosion-resistant, marine-grade aluminum construction, the Kuuma 11812 withstands the harsh saltwater and humid environments that destroy standard freshwater appliances. The 6-gallon capacity delivers adequate hot water for showers, galley use, and cleaning without consuming excessive cabin space or drawing excessive electrical demand from limited onboard power systems. Operating on standard 120V electrical supply, the heating element provides steady, efficient water temperature control—critical when shore power or a generator is your only electricity source during extended anchorages.

Boaters maintaining vessels between 25 and 50 feet will find this heater ideally sized for crew comfort without overloading electrical infrastructure. Installation requires basic marine plumbing knowledge and standard 120V circuits; consult your vessel's electrical schematic and water system layout before purchasing. The 11812 pairs well with onboard water systems using freshwater tanks and circulation pumps, making it compatible with both trawlers and sailboats equipped with modern galley systems. At 22 pounds and measuring 16 x 16 x 22 inches, it fits compact engine rooms and utility lockers on vessels where space management is critical.
