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, which is up to 40% more efficient than regular systems. This unit proves that sometimes, less is more. More efficiency, more savings, more comfort for your home. Technology is key to the GWM-IE’s efficiency. It includes 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. 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. 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 minimizes the chances of corrosion and leaking. A wall-hung design makes it possible to save more space. We’re convinced...what about you?
