GWM-IE Boilers Offer the Highest Efficiency that will Keep You Warm For the finest option available 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 – that’s up to 40% more efficient than traditional boilers. This unit proves that sometimes, less is more. More efficient, more savings, more comfort for your family. Technology is key 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 produces an even temperature without turning on and off, so you can have a quieter home. Further, 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 guarantees safe operation. A CPVC flue condensate collector protects against corrosion and leaking. A wall-hung design makes it possible to save more space. We’re convinced...what about you?
