GWM-IE Boilers Offer the Highest Efficiency that will Keep You Warm For the most efficiency 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. That’s an efficiency rating 40% higher than standard boilers! This unit proves that sometimes, less is more. More efficiency, more savings, more comfort for you. Technology is key to the GWM-IE’s efficiency. It includes a modulating burner that operates primarily on a low-flame setting and changes settings as necessary. This distributes an even temperature without turning on and off, so you can have 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. Now that we’ve got you hooked, 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 safeguards against corrosion and leaking. A wall-hung design makes it easy for you to save space with its wall mounting ability. We’re convinced...what about you?
