incredibly efficient GWM-IE High-efficiency, gas-modulating condensing water boiler

High quality and innovation, boiled down into one incredibly efficient system. Designed to maximize fuel savings, the Lennox® GWM-IE boiler delivers up to 40% greater efficiency than conventional boilers. The GWM-IE’s burner matches heating output to household demand, using only the energy necessary to keep warm water flowing through pipes into your radiators or baseboard heating system. What all that boils down to is an incredible opportunity to cut back on utility costs, without compromising comfort. AFUE stands for “Annual Fuel Utilization Efficiency” and is a measure of a boiler's efficiency...

design that’s highly innovative and efficient Technology with the power to save you money year round Highly effective at recovering heat that would otherwise be wasted Depending on the heating requirements of your home, the GWM-IE’s modulating burner can fire at a rate as low as 20% of its full capacity, saving you substantially on fuel costs. By operating mostly at a low flame setting, and making gradual output adjustments as necessary, the GWM-IE’s modulating technology maximizes efficiency. At the heart of the GWM-IE boiler is a vertical heat exchanger made of premium stainless steel. Inside...
