GWM-IE Boilers Offer the Highest Efficiency that will Keep You Warm For the finest option available in boilers, go with the Lennox® GWM-IE high-efficiency, gas-modulating condensing water boiler. This product achieved ENERGY STAR® certification and a 95% AFUE efficiency rating, which is up to 40% more efficient than regular systems. The GWM-IE proves that sometimes, less is more. More efficient, more savings, more comfort for you. Technology is key to the GWM-IE’s efficiency. Some of this technology is shown through a modulating burner that operates primarily on a low-flame setting and adjusts as necessary. This helps produce an even temperature without turning on and off, resulting in a quieter home. Moreover, the condensing water feature we mentioned earlier helps retain heat that would otherwise be wasted, thanks to specially designed tubes in the vertical stainless steel heat exchanger. Have we captured your attention? Let’s switch gears. The GWM-IE boiler is safer and more convenient than standard 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?
