Tankless water heaters have been growing in popularity for decades, but there are still common misconceptions that surround the technology, impacting purchase decisions by both the pro and customer alike.

A. O. Smith has combined its water heating and water treatment expertise to achieve unparalleled protection with its new X3 Scale Prevention Technology — now included on its suite of condensing gas tankless products, the company says.

Rheem commercial tankless water heaters are designed to deliver continuous, dependable hot water, save money and space, and keep business up and running workday after workday, the company says.

With the improved SENSEI RSC condensing tankless water heater, Rinnai delivers the same superior quality with simplified installation, the company says.

Navien’s NPE-2 condensing tankless water heaters include a turndown ratio up to 15:1, advanced EZNav multi-line control panel with Setup Wizard, and 2” PVC venting up to 75’.

The TTS Synergy Series line by FRG offers high-performance tankless rack systems in a wide range of configurations, with one point of connection for water, power, gas, venting and a condensate drain.

The Greentherm 9000 gas tankless water heater offers a UEF efficiency rating up to 0.96, top water connections for easy tank replacement and an industry-leading warranty, the company says.

Bernard Beyer joins Rinnai as vice president of information technology; Sean Boyer joins as vice president of quality assurance; and Buster Kennett joins as vice president of finance.  

The TTS Synergy Series features a turndown ratio of 66:1 that will provide more than 1,600 gallons of hot water per hour, yet is compact enough to fit through a standard mechanical room doorway, the company says.

The EZ Series of high-efficiency, condensing tankless water heaters cut installation time and cost when replacing larger, storage tank-type units, Noritz notes.
