The WM97+ wall-mounted, gas-fired, hot water boiler from Weil-McLain sets new standards for quality and efficiency. With seasonal DOE efficiency ratings of over 95 percent, the three available models waste minimal amounts of fuel. They feature a built-in primary circulator, low water cutoff, and expansion tank (WM97+ 70 and WM97+ 110 only). Convertible to propane with an included kit, the boilers contain stainless steel heat exchangers, three-zone circulator controls, and indirect water heater connections. The WM97+’s color LCD display conveniently displays text-based error codes, eliminating the need to check the manual every time a problem occurs. The boiler is designed for direct vent combustion.
Take advantage of an Aqua Logic indirect water heater to use the boiler’s energy for your domestic water needs. In addition to connecting directly to the bottom of a WM97+ boiler, the AquaLogic provides many benefits of its own. It offers a stainless steel tank, coil, and connector pieces, along with a vacation mode for energy savings during periods of extended non-use as well as personalized scheduling options. The AquaLogic minimizes temperature swings when multiple fixtures run simultaneously and includes two tank temperature sensors.
