Non-condensing commercial boiler


Rinnai America Corporation, Atlanta, Georgia, releases their new line of non-condensing Demand Duo R-Series Commercial Hybrid Water Heating System to market. Its design connects easily to existing six-inch B-vent, allowing contractors to replace standard-efficiency atmospheric tanks. Sold in 8 or 119 gallon tank options, the Demand Duo R-Series eliminates the need for new vent penetrations. The pre-installed drip leg and 36-inch Swivel-Flex Gas Line creates material efficiencies and reduces install time with a pre-installed electrical junction box and duplex outlet.
