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 earned 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 efficient, more savings, more comfort for your home. 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 helps produce an even temperature without turning on and off, which results 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. 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 allows for safe operation. A CPVC flue condensate collector minimizes the chances of corrosion and leaking. A wall-hung design makes it possible to save more space. We’re convinced...are you?
