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 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 a key component of the GWM-IE’s efficiency. Some of this technology is shown through a modulating burner that operates primarily on a low-flame setting and makes adjustments as necessary. This produces an even temperature without turning on and off, so you can have a quieter home. Further, the condensing water feature we mentioned earlier helps trap in 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 traditional boilers. A factory-installed low water cut-off switch guarantees safe operation. A CPVC flue condensate collector protects against corrosion and leaking. A wall-hung design makes it easy for you to save space with its wall mounting ability. We’re convinced...how about you? Take a look at the GWM-IE boiler product brochure to learn even more.
