Kuuma 11812 120V 6 Gallon Marine Water Heater - Front Mount, Rear Heat Exchange

The Kuuma 11812 is a 6-gallon, 120V marine water heater built to bring hot water on board for galley clean-up, dish washing, laundry, or rinsing off after a swim. It uses a front-mount, rear heat exchange configuration, with all plumbing and electrical connections located at the front of the unit for easier installation and service in the tight equipment spaces typical of smaller vessels.

Heating is provided by a 1500W element running on 120V, 60Hz AC power (L1 and N wiring configuration), so the tank can be heated dockside from shore power or a generator. A temperature and pressure relief valve rated to 100 psi and 210 degrees F (CSA listed) is built in for safe operation. The unit and its interior casing are constructed from marine-grade aluminum, engineered to resist corrosion in wet, humid marine environments and suitable for use in salt water conditions.

At 13.75 inches wide by 13.625 inches high by 19.75 inches deep, the Kuuma 11812 is sized to fit into compact onboard equipment spaces while still supplying a useful 6-gallon capacity of hot water for smaller vessels.
