The Mighty Stack volume water heater combines the Mighty Therm 2 boiler with an 80-gallon storage tank resulting in 199-, 300-, and 399-MBtuh sizes. It is fueled by natural or propane gas. With less than 10-ppm NOx emissions, the sealed-combustion Mighty Stack offers 83 percent thermal efficiency and meets low lead requirements. The light commercial product is designed for apartments, restaurants, hotels, laundries, schools, businesses, and large homes. Key assets include its small footprint, a removable upper boiler section for easy handling, common venting, and up to 50 feet of Category I or III venting. Thanks to the rugged steel cabinet, the new Mighty Stack can be installed inside or outside. Standard components include tank aquastat, pressure relief valve, hot surface pilot ignition, and an integral induced-draft fan to allow for either horizontal or vertical venting. The Mighty Stack is factory pre-assembled, then operationally tested to ensure trouble-free startup with no time-wasting field adjustments required, says the company.
