GWM-IE Boilers Offer the Highest Efficiency that will Keep You Warm For the most efficiency in boilers, go with 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 up to 40% more efficient than traditional boilers. This boiler proves that sometimes, less is more. More energy efficient, more savings, more comfort for your family. Technology is a key component of 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, resulting in 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. 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 allows for 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...what about you?
