How do Bosch Tankless Water Heaters work?

Since Bosch tankless water heaters don’t have storage tanks, there is no standby heat loss (wasting energy on heating water stored in a tank) which makes them energy efficient.

Bosch water heaters work the same way – when a hot water tap is opened, cold water enters the heater and triggers the heating element (heat exchanger) or burners to turn on. As water flows through the heating elements it heats up. When you change the water flow, a water valve or thermostat controls the heating elements or burner flame and maintains a constant temperature. The amount of energy you use is always in proportion to the volume of hot water used, shutting down when you turn the hot water tap off.

The heat exchanger used in the tankless water heaters can be electric resistance heating coils or a gas-fired burner using natural gas or propane. Usually, natural gas tankless water heaters have more heating capacity so larger whole-house units would be gas fired.

For Bosch gas tankless water heaters the saving is typically 30% of your energy usage, saving you dollars and reducing the impact on the environment. In addition, by installing a tankless hot water

heater you can also qualify for a Rebate offered by Enbridge or Union Gas depands upon the area you live in.
