LCD Display Control: Just set the desired water temperature The Excel Pro has an energy factor of 0.84-0.85. Excel Pro: Modulating Technology Tankless water heaters can be further divided into two categories according to their heating capability: "full on/full off" versus "modulating". Full on/full off units do not have a variable power output level; the unit is either fully on or completely off. This can cause an annoying and possibly hazardous variation of hot water temperature, as the flow of water through the heater varies. Modulated tankless water heaters change their heat output in response to the flow rate of water running through the unit. The Excel Pro comes with a display panel where you can set the output temperature and regardless of water flow the unit modulates the fire power.
