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 received ENERGY STAR® certification and a 95% AFUE efficiency rating. That’s an efficiency rating 40% higher than standard boilers! This unit proves that sometimes, less is more. More efficient, more savings, more comfort for you. 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 helps produce an even temperature without turning on and off, so you can have a quieter home. Additionally, 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 traditional 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 for you to save space with its wall mounting ability. We’re convinced...are you?
