Kuuma 11810 6 Gallon 120V Marine Water Heater, Side Mount, Front Heat Exchanger

The Kuuma 11810 is a 6-gallon, 120V marine water heater built for boats where onboard hot water is needed for washing dishes, cleaning up after a swim, or rinsing off gear after a day on the water. It uses a side-side mount arrangement, making it suited to installations where the plumbing and electrical connections need to run off the sides of the unit rather than the front or rear. The unit is heated electrically through a 1500W heating element running on 120V, 60Hz power with an L1 & N wiring configuration, so it can be run off shore power or an onboard generator.

Heat transfer is handled through a front-positioned aluminum heat exchanger, and the tank itself is constructed of marine-grade aluminum, a material chosen for its resistance to corrosion in the wet, humid conditions typical of a boat's water heater compartment. Safety is handled by a temperature and pressure relief valve rated to 100 psi and 210 degrees F and certified to CSA standards. At 15.625 inches wide, 13.625 inches high, and 19.375 inches deep, the 11810 is sized to fit into the tighter equipment spaces common on boats, and it weighs 20 pounds. This model is part of the Kuuma line of marine water heaters, sold under the Kuuma brand.
