GWM-IE Boilers Offer the Highest Efficiency that will Keep You Warm For the finest option available 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. The GWM-IE 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. Have we captured your attention? Let’s switch gears. The GWM-IE boiler is safer and more convenient than conventional boilers. A factory-installed low water cut-off switch ensures 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?
