Standard-Efficiency GWB8-IE Boilers Create a Warm and Energy Efficient Home Without details behind the GWB8-IE name, it might not be as easy to tell why this Lennox® boiler is such a great product. We’re here to help you learn about the benefits. Three features define the strengths of the GWB8-IE. They include: Energy efficiency You’ll see efficiency ratings on the GWB8-IE reach up to 84.4%, delivered by an electronic ignition control and thick fiberglass insulation. While these features turn the burner on only when it needs to be, they also monitor water temperatures and reduce off-cycle energy losses. Comfort Integrate the GWB8-IE with your radiator system so you can experience precise heating and warm rooms, no matter what the weather outside is like. Reliability The GWB8-IE is made with titanium burners and a cast iron heat exchanger. These two features work together to stop corrosion and oxidization to keep your boiler in prime working condition for years.
