ANSWER TO QUESTION #6

<< return to Question & Answer

Flow switches do not regulate temperature. They only turn on power circuits that allow the heating elements to be turned on when hot water use starts on and off when use stops.

The tankless water heater microprocessor control does not need or use any moving parts in the water path - including a flow switch. There is no flow switch that has been designed that can eliminate latent heat.

Unlike a tank, you can and should operate any tankless water heater at lower temperatures, but this won’t change the BOILING from tankless water heaters in which that single element will always be turned on FULL POWER at shut down.
