GWM-IE Boilers Offer the Highest Efficiency that will Keep You Warm For the finest option available 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 efficiency, more savings, more comfort for your family. 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 adjusts as necessary. This produces an even temperature without turning on and off, which results in a quieter home. Moreover, 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. Have we captured your attention? Let’s 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...how about you?
