GWM-IE Boilers Offer the Highest Efficiency that will Keep You Warm For the most efficiency 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. That’s an efficiency rating 40% higher than standard boilers! This unit proves that sometimes, less is more. More efficiency, more savings, more comfort for you. Technology is a key component of 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 distributes an even temperature without turning on and off, resulting in a quieter home. Further, the condensing water feature we mentioned earlier helps trap in 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 easy for you to save space with its wall mounting ability. We’re convinced...how about you?
