How does the Rheem tankless water heater work?
A conventional tank-style water heater stores hot water, and heats the water 24/7, whether you use it or not. The new generation Tankless Technology Water Heater from Rheem only heats water on demand. When the faucet is opened, the water flows through the Rheem Tankless Water Heater, which heats it to the temperature you’ve digitally set. When the faucet is closed, the Rheem Tankless Water Heater senses the command, and goes to standby mode.
