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 – that’s up to 40% more efficient than traditional 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. It includes 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. 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. Have we captured your attention? Let’s switch gears. The GWM-IE boiler is safer and more convenient than conventional boilers. A factory-installed low water cut-off switch guarantees safe operation. A CPVC flue condensate collector protects against 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?
