GWM-IE Boilers Offer the Highest Efficiency that will Keep You Warm For the best in boilers, choose 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 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, which results 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. Since we have your attention, we’re now going to switch gears. The GWM-IE boiler is safer and more convenient than traditional 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 to mount on the wall so you can save space. We’re convinced...are you? Check out the GWM-IE boiler product brochure to learn even more.
