The ADK-4 is a 110 Volt unit for light duty heat rise, operating at 4 kilowatts at a Max of 29 Amps using a 30 Amp breaker. The temperature rise chart illustrates the flow rates and temperature rise which can be achieved with different ADK Models. The chart is based on a 240 volt input voltage and maximum flow rates are listed for various incoming water temperature levels. Simply look up your incoming water temperature and desired flow rate to determine your model choice. Temperature of your incoming water change throughout the year. When planning the final replacement of your old tank water heater then be sure to find the cold incoming water in the winter when calculating your temperature rise.
