GWB8-E: A Gas-Fire Water Boiler You Can Depend On The Lennox® GWB8-E offers warmth effectively when you need it most. This boiler includes a cast iron heat exchanger and stainless steel burners designed to prevent corrosion and oxidation1 and last for years. Effective heat year after year? It can’t get much better than that. Similar to our some of our other products, this boiler has an electronic ignition control that only turns on the burner when it’s needed. Energy savings are maximized with a thick fiberglass insulation and vent damper, which closes by itself when the boiler turns off. In fact, its efficiency ratings can add up to nearly 84% AFUE, leading to more dollars subtracted from your monthly utility bills. The GWB8-E makes our installation job even easier. It’s simple to connect with your radiator system and it’s available in a variety of sizes. That means you can install this boiler almost anywhere in your home. Concerned about using natural gas? No problem. The GWB8-E can be fueled by LP gas instead.2 Containing three qualities we want to see in a boiler, the GWB8-E has it all: reliable parts, energy efficiency and dependability.
