GWM-IE Boilers Offer the Highest Efficiency that will Keep You Warm For the best in boilers, go with the Lennox® GWM-IE high-efficiency, gas-modulating condensing water boiler. This product received ENERGY STAR® certification and a 95% AFUE efficiency rating. That’s an efficiency rating 40% higher than standard boilers! The GWM-IE proves that sometimes, less is more. More energy efficient, more savings, more comfort for your family. Technology is a key component of the GWM-IE’s efficiency. It includes a modulating burner that operates primarily on a low-flame setting and makes adjustments as necessary. This produces an even temperature without turning on and off, which results in a quieter home. Moreover, the condensing water feature we mentioned earlier helps keep in the heat that would otherwise be wasted, thanks to specially designed tubes in the vertical stainless steel heat exchanger. Since we have your attention, we’re now going to switch gears. The GWM-IE boiler is safer and more convenient than conventional boilers. A factory-installed low water cut-off switch guarantees safe operation. A CPVC flue condensate collector safeguards against corrosion and leaking. A wall-hung design makes it possible to save more space. We’re convinced...how about you? Browse through the GWM-IE boiler product brochure to learn even more.
