Water heater manufacturer A. O. Smith (hotwater.com) is launching the Simplicity Series of concentric venting, noncondensing tankless water heaters — designed to make installations simple and flexible through a new gas convertible combustion system.

The Simplicity Series models come in three sizes and are designed to easily convert from natural gas to propane – with all necessary components already in the box. This new line will assist distributors in managing their inventories by reducing the number of product variations needed, which ensures product availability as well.
