remotely and even stop a scheduled event from starting. Rheem manufactures WiFi-enabled tank- less products that merge seamlessly with both Nest and Wink smart home systems. e units also can combine with the company's EcoNet smart home network to give home- owners additional control over their heating, cooling and water-heating systems. "Plumbers also benefit from the greater functionality, which encourages repeat main- tenance calls and offers system monitoring and diagnostic alerts," Maxwell says. e most recent product offering from Stiebel Eltron, who invented the first elec- trical tankless water heater in 1929, can be installed on either the inlet or outlet side of any hot water tank, gas or electric. It sup- plies greater amounts of water than a tank can yield by itself and reduces recovery time, says Erika Knerr, marketing coordinator for Stiebel Eltron. "MegaBoost is especially useful for instal- lations where a smaller capacity tank must be used to replace a larger tank," she adds. | notes David Federico, brand director for the Rinnai America Corporation. "Rinnai's com- pany engineering team has also improved the serviceability of the [Sensei tankless] product; every component was designed to be removed in under 10 minutes." Federico says Rinnai has become the first tankless water heater manufacturer to feature Amazon Alexa integration with its products as well. "is groundbreaking in- novation allows users to ask Alexa, 'Alexa, ask R innai to start circulation,' or say, 'Alexa, tell Rinnai I want to take a shower,' and the Rinnai tankless water heater will spring into action," he adds. e enhanced Control-R 2.0 module with Amazon Alexa integration showcases a user- friendly interface—with more than 20 voice commands—that enables on-demand voice activation of the recirculation system, Federico explains. e enhanced Control-R 2.0 mobile app includes built-in timers and schedules to allow multiple on/off periods throughout the day, and the app permits users to put the system in vacation mode electric tankless water heater may require a 100- or even 140-amp circuit and up to 6-gauge wire." e Noritz EZ Series of tankless water heaters includes the EZTR50 and EZTR75 models, which provide direct replacement of 50- and 75-gallon storage tank-type units, Tran says. eir top-mount water connec- tions, ability to utilize an existing B-vent and possibility for a ½-inch gas line can simplify installation. "ese features [provide] major time and labor savings for contractors—and significantly narrow the cost gap between a tank and tankless water heater," he adds. Tankless units operate more efficiently by heating water only as it is being used, and they do not incur the standby energy loss that tank water heaters experience. A tank water heater has a bigger footprint too—roughly 24 inches in diameter and 50 inches high— compared with a tankless unit, which usually resembles a carry-on suitcase and fits into a utility closet or other confined area. "e biggest challenge in any tankless installation is making sure to size the unit properly for the application," Smith says. "Since the unit is heating water on demand, the contractor needs to size it for the maxi- mum number of showers, sinks and laundry cycles that could be used at the same time. If a contractor sizes [the water heater] for average use, it's possible that the tankless [unit] will not be able to provide sufficient hot water for all the fixtures—or at peak demand periods." A.O. Smith developed a water-heater se - lection tool, Xpert, to guide contractors and homeowners through the decision-making process by asking questions about hot water usage in the household, he adds. WHERE THEY MATTER Many of the advancements in tankless tech- nology focus on making the product more flexible and easier for contractors to install and maintain. Rinnai recently launched the Sensei Tankless Water Heater and designed its combustion system to self-compensate in areas with low or fluctuating gas pressures for optimized performance. Some situations even accommodate a ½-inch gas line. "e product offers a total of 14 vent con- figurations, a 65-foot vent run with 2-inch PVC, and quick-and-easy gas conversion," A.O. SMITH 's ProLine XE Combination Boiler (left) delivers immediate hot water and comfortable space heating, while its ProLine XE 540P Tankless Water Heater with Recirculation Pump (right) provides instant hot water in homes with dedicated recirculation lines.
