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! This boiler proves that sometimes, less is more. More energy efficient, more savings, more comfort for your family. 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 makes adjustments as necessary. This produces an even temperature without turning on and off, resulting 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. 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 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?
