The gas-fired, high-efficiency Combi 160 and Cast 92 condensing boilers are Energy Star®-rated. The 93 percent efficient Combi 160 uses premixed burner technology for optimal combustion. The boiler offers hydronic heat and domestic hot water in one complete unit by using an integrated coil-type hot-water tank. The built-in tankless heater is capable of producing up to 4 gallons of domestic hot water per minute for ample, low-cost domestic hot water without the expense of a separate water heater. Other features include a patented premix air/gas modulation system, an installed and wired circulator, and expansion tank. The wall-mounted boiler design allows for ease of installation, maintenance, and service. The Cast 92 cast iron boiler has a 92.7 percent AFUE and can be used with either natural or LP gas. No additional parts are required for the gas conversion; to convert it, reset the combustion settings and add a new label to the boiler. The boiler features direct spark ignition and is environmentally friendly with low emissions for both CO2 and NOx. According to the manufacturer, due to its unique design and simplicity, there is no need for primary/secondary piping.
