Rated 5 out of 5 by from Needed more room for storage. Great product, this unit seems to be working as advertise. It takes about 12 second for the water to start getting warm in by bathroom. Which this is not much different from my other water heater. Never run out of hot water.

Rated 5 out of 5 by from Saves space, noise, and money Replaced 72 gallon tank with AO Smith's tank-less water heater no loss in performance. No more cold water when filling our garden tub. Can not wait to see the gas bill.

Rated 4 out of 5 by from Nice safety features. Had a week, so far working good. Except yesterday, it didn't work, for a short time period. We took the cover off and put space heater near it, to warm it up , which worked. We did not lose any power at any time. We are having some very cold windy weather, and are pretty sure that the cold went through the exhaust PVC pipe. It works fine now, no damage done. It should come with a back flow preventer...standard.

Product Features & Options

Primary Heat Exchanger

The primary heat exchanger is constructed of commercial-grade HRS35 copper, which is stronger than standard copper and more resilient against erosion.

Safety Features

Includes freeze, overheat, surge protection and troubleshooting diagnostic codes.

Space Savings

A. O. Smith tankless water heaters take up much less space that your conventional tank-style water heater. With no tank to steal valuable storage space, our wall-mount design allows for additional storage and flexibility.

Endless Hot Water

The comprehensive line of A. O. Smith tankless water heaters are an excellent whole-home water heating solution that supply endless hot water.

How it Works

The comprehensive line of A. O. Smith tankless water heaters provide hot water on-demand.

• 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
