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. Also featuring a built-in recirculation pump (SR models), Rheem IKONIC offers homeowners no wait access to continuous hot water, preventing up-to 12,000 gallons of water from being wasted down the drain each year.

Noritz has expanded its line of combination boilers with the new Noritz Residential Combination Boiler (NRCB), which allows for simultaneous residential domestic hot water and space heating and performs at a 95% AFUE. Available in two models, the NRCB180DV has a maximum gas input Btu/h of 180,000 for hot water and 100,000 Btu/h for space heating with a maximum flow rate of 9.8 gallons per minute (gpm), and the NRCB199DV has a maximum gas input Btu/h of 199,000 for hot water and 120,000 Btu/h for space heating with a maximum flow rate is 11.1 gpm.

The Trane Thermafit air-to-water modular heat pump Model AXM is a fully electric modular unit that owners can scale to match a building’s heating or cooling load. By combining individually controlled AXM modules to create a single, larger heat pump, operators can right-size heating and cooling performance to meet a wide range of applications. Each module is capable of 30 tons of cooling and 390,000 MBtu/h of heating and is expandable to generate up to 300 tons of cooling. Dual refrigerant circuits on each heat pump provide precise temperature control. Controls with open standard protocols that seamlessly integrate with Tracer SC+ and third-party Building Automation Systems (BAS).

Saniflo's Sanibest Pro macerating toilet system uses a smaller amount of water than conventional toilets: 1.28 gpf vs. 1.6 gpf, but with no sacrifice in flushing power. It is also eligible for LEED certification, and recognized as water-saving by the EPA’s WaterSense program. The Sanibest Pro is used to install a complete bathroom up to 25 feet below the sewer line or up to 150-feet away from the soil stack. This one-horsepower pump system contains three inlets to handle drainage for a full bathroom. Aside from the 4-inch inlet for toilet connection, a 2-inch inlet on either side of the unit easily connects to other sanitary fixtures — a sink, a bathtub or a shower — to drain greywater.
