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 received 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 efficiency, 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 makes adjustments as necessary. This distributes 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 ensures 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? Take a look at the GWM-IE boiler product brochure to learn even more.
