Water Heater Brochure

• A hot water tap is opened.
• The opened tap allows water to flow
through the water heater. An internal
water flow sensor detects this flow.
• Upon flow detection, the flow sensor
sends the activation signal to the
computer board.
• The computer automatically ignites the
burner.
• As water flows through the heat
exchanger, it absorbs heat from the
burner.
• By the time the water exits the heater,
it has reached the designated set
temperature.
• When the hot water tap is closed, the
water heater automatically turns off.
How It Works – The Process:
HOW DOES A TANKLESS
WATER HEATER WORK?
1. A hot water tap is turned on
2. The ow sensor detects the
water ow
3. The computer automatically
ignites the burner
4. Water circulates through the
heat exchanger
5. The heat exchanger heats
the water to the designated
temperature
6. When the tap is turned off,
the unit shuts down

TANKLESS ADVANTAGE
Endless Hot Water
Heating water only as it’s being used means you will never run out of hot water again. After the few seconds it
takes for the water to reach the designated set temperature, our water heaters will continually provide a steady
flow of hot water for as long as your application needs it (when sized appropriately for your home's needs).
Energy Conservation
Provides you with continuous hot water in one of the most energy-efficient ways possible. Conventional tank-type
water heaters will heat and store a set volume of water, regardless of whether someone is using that hot water or
not. Because our tankless water heaters only activate when hot water is being used, no standby energy losses are
incurred, providing efficient heating while conserving energy.
Compact Size
On top of all this, an A. O. Smith tankless water heater takes up much less space than your conventional tank-type
water heater or boiler. A. O. Smith’s wall-mount design offers flexible installations freeing up valuable storage space.
