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. This unit proves that sometimes, less is more. More energy efficient, more savings, more comfort for your family. Technology is key to the GWM-IE’s efficiency. Some of this technology is shown through 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. Moreover, the condensing water feature we mentioned earlier helps keep in the 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 conventional boilers. A factory-installed low water cut-off switch allows for safe operation. A CPVC flue condensate collector protects against corrosion and leaking. A wall-hung design makes it possible to save more space. We’re convinced...how about you?
