How do electric water heaters work?
When you turn on the tap for hot water, your electric water heater heats up the water inside the tank using submerged heating elements powered by your home's electrical system. Your unit comes with a thermostat that monitors the temperature and turns off the heating elements once the desired temperature is reached, keeping the water consistently hot until you're ready to use it. By understanding how your electric water heater operates, you can fully appreciate the technology that supplies you with hot water whenever you need it.
