Water heater brand A. O. Smith has entered the electric tankless market with new products offering innovative features and benefits previously unavailable in this category.
The new ProLine series electric tankless units can be used for residential and point-of-use applications.
“We’re excited to bring the ProLine Electric Tankless family to our partners, who can now offer a complete line of A. O. Smith products to their customers,” says David Chisolm, vice president of marketing at A. O. Smith. “Contractors will be extremely comfortable installing these units—which plumb very similarly to standard electric water heaters—and end-users will appreciate their compact size, reliability and energy-saving capabilities.”
The ProLine heater models have true Dry Fire Protection, which means the element will only turn on when the chamber is full of water so plumbers and electricians have the freedom to work without fear of costly dry fires, the company says. All models also have Scale Reduction Technology. “This feature reduces scale formation on the elements and on the chamber walls, which reduces failures and service requirements,” A. O. Smith says. “Further, the units do not contain any moving parts or screens—another common place scale buildup can occur.”
The company also explains that the single-chamber design, which features a pre-heat function that helps bring domestic hot water faster to the fixture, is compact enough to be mounted directly under a sink, in a remote bathroom or other hard-to-plumb area.
ProLine products are available in three sizes, with 45 different models ranging from 2.4kW to 32kW and Uniform Energy Factor up to 0.93. The units are available in voltage options, including 120V, 208V, 240V, and 277V.
“The largest unit in the family, the four-chamber model, can produce up to 4.25 gallons of hot water per minute—enough to support 2.5 baths in a whole-home or multi-family application,” the company explains. “The two-chamber design is ideal for applications where the heater is close to where the hot water is being used, such as cabins. Both sizes feature a soft start power draw, so that lights do not dim during a heavy power draw.”
