GWM-IE Boilers Offer the Highest Efficiency that will Keep You Warm For the finest option available in boilers, select the Lennox® GWM-IE high-efficiency, gas-modulating condensing water boiler. This product earned ENERGY STAR® certification and a 95% AFUE efficiency rating, which is up to 40% more efficient than regular systems. This unit proves that sometimes, less is more. More energy 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 produces an even temperature without turning on and off, resulting in a quieter home. Additionally, 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. Now that we’ve got you hooked, let’s switch gears. The GWM-IE boiler is safer and more convenient than traditional boilers. A factory-installed low water cut-off switch ensures safe operation. A CPVC flue condensate collector protects 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?
