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 received ENERGY STAR® certification and a 95% AFUE efficiency rating. That’s an efficiency rating 40% higher than standard boilers! The GWM-IE proves that sometimes, less is more. More efficient, 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 adjusts as necessary. This distributes 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. 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 guarantees safe operation. A CPVC flue condensate collector protects 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? Browse through the GWM-IE boiler product brochure to learn even more.
