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 an efficiency rating 40% higher than standard boilers! The GWM-IE proves that sometimes, less is more. More efficiency, more savings, more comfort for your home. Technology is a key component of 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 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 retain 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 minimizes the chances of corrosion and leaking. A wall-hung design makes it easy to mount on the wall so you can save space. We’re convinced...are you? Check out the GWM-IE boiler product brochure to learn even more.
