GWB8-E: A Gas-Fire Water Boiler You Can Depend On

Lennox GWB8-E BoilerThe Lennox® GWB8-E provides warmth at the times you need it most. This boiler uses a cast iron heat exchanger and stainless steel burners designed to prevent corrosion and oxidation1 and last for years. Reliable heat year after year? It’s just as sweet as it sounds.

Similar to our other boilers, this boiler has an electronic ignition control that only turns on the burner when it’s needed. It further maximizes energy savings 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 a decrease in your utility bills.

The GWB8-E makes our installation job even easier. It’s easy to integrate with your radiator system and it’s available in nine sizes. That means you can install this boiler almost anywhere in your home. Don’t want your boiler to use natural gas? That’s okay. 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: well-made parts, energy efficiency and dependability.
