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 a great product. We’re here to spell out the benefits for you. Three things define the strengths of this system. They include: Energy efficiency You’ll see efficiency ratings on the GWB8-IE total up to 84.4%, brought 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 to 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. Put together, these features stop corrosion and oxidization, keeping your boiler in prime working condition for years.
