All Kuuma 120V AC corrosion-resistant Water Heaters have
* Aluminum tanks and aluminum alloy casings.
* A 7/8" heat exchanger for more efficient heat control through increased surface area
* Ignition-protected controls
* High temperature / high pressure valve installed.
When the Water Heater is operating from the AC Power, water temperature in the tank is regulated at 140 deg F (60 deg C). The thermostat is non-adjustable.
Warning: This unit is not equipped with a Temperature Control Valve. When the Water Heater is operating from the Heat Exchanger, water temperature in the tank will approach the temperature of the engine coolant.
NOTE: Small DC electric currents move between boat and shore through the safety ground wire in the shore cord, causing galvanic damage to your water heater. To prevent galvanic damage, this product should be used in conjunction with a galvanic isolator. These devices are inexpensive and easily installed. Galvanic corrosion is not covered by warranty.
