Navien announced three new innovations, including their first HVAC product, during a virtual launch event on September 26. 

Intellihot introduces the Electron tankless heat pump water heaters, the first such technology for commercial applications, the company says.

Merging the benefits of storage in a standard tank water heater with the efficiency of tankless into one powerful unit, the new Hybrid Hot Series provides a continuous hot water supply and quick hot-water recovery with a 10-year warranty.

The TTS Synergy Series tankless rack solution 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.

With stainless steel heat exchangers, optional commercial rack mounts and multiple venting options, the GS and GR tankless water heater models combine reliability with flexibility to meet the demands of both residential and commercial applications and accommodate a variety of installations, the company says.

Rheem IKONIC super high efficiency condensing gas tankless water heater delivers a 0.96 UEF, resulting in up to a 36% reduction in energy use and carbon footprint and up-to 65% reduction in NOx emissions, the company says.

The IKONIC high efficiency condensing gas tankless water heater delivers a best-in-class 0.96 UEF, resulting in up to a 36% reduction in energy use and carbon footprint and up-to 65% reduction in NOx emissions, 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.

The commercial water heating market has options for building owners and facility managers when it comes to selecting equipment for their facilities — tank or tankless, gas models or electric — even heat pump water heaters are seeing growth in this space. So which is the most popular? Well, it all depends on who you ask.
