HEAT UP CYCLE WITH ELECTRICAL ELEMENT
The Super Stor marine water heater is equipped with an immersion type electrical element. This high quality 1500 watt, 110/120 volt AC device is factory installed and sealed to prevent leaking. Each element is constructed of tough stainless steel, which is designed to withstand accidental operation in an empty tank. A factory calibrated thermostat is UL approved for spark ignition protection.

HEAT UP CYCLE WITH HEAT EXCHANGER AND ENGINE COOLANT
Water heat-up is very effective with the factory installed finned tube heat exchanger with extra heat surface. The unique design of the unit and its finned tube heat exchanger promote rapid heat transfer from the engine coolant water to the tank water. The finned tube heat exchanger has a 1/2" threaded connection to the tank and the tank is pressure tested to assure a leak proof system. The location of the heat exchanger within the tank is critical to the performance and recovery rate of the product. To optimize the heat exchanger design, it is installed at the base of the tank (heat rises); instead of mid-height as some competitive brands do. This provides a full six U.S. gallons of hot water. Also, the cold water inlet is at the same level as the heat exchanger, to provide a “scrubbing” action to mainfain a clean surface for optimum output. Extensive testing shows that a 2 1/4 ° F per minute rise with constant 1600 F input to the heat exchanger is typical. Also, the average water temperature in the tank is higher than competitive brands because of the location of the heat exchanger (which also means longer showers!) (See Figure 2)

HEAT LOSS CYCLE
The environmentally safe water-blown foam insulation offers resistance to heat loss. In a 35 hour test period, a total of 1 7°F was lost (average .4°F per hour). More importantly, is the first hour where less than 1/2°F was lost. Comparative results from other brands averaged nearly 7°F per hour losses and up to 12°F for the first hour (See Figure 3)
