GWM-IE Boilers Offer the Highest Efficiency that will Keep You Warm For the best in boilers, select 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 up to 40% more efficient than traditional boilers. The GWM-IE proves that sometimes, less is more. More efficient, more savings, more comfort for you. Technology is the secret to the GWM-IE’s efficiency. For example, these boilers include a modulating burner that operates primarily on a low-flame setting and changes settings as necessary. This distributes an even temperature without turning on and off, which results in a quieter home. Further, 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 allows for safe operation. A CPVC flue condensate collector minimizes the chances of corrosion and leaking. A wall-hung design makes it easy to mount on the wall so you can save space. We’re convinced...how about you?
