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 unit proves that sometimes, less is more. More energy efficient, more savings, more comfort for your home. 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, resulting in a quieter home. Additionally, 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. Since we have your attention, we’re now going to 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 protects against 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? Check out the GWM-IE boiler product brochure to learn even more.
