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 features a cast iron heat exchanger and stainless steel burners designed to resist corrosion and oxidation1 and last for years. Effective 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. Energy savings are maximized with a thick fiberglass insulation and vent damper, which closes on its own when the boiler turns off. In fact, the GWB8-E’s efficiency ratings can add up to nearly 84% AFUE, leading to reduced energy bills.

The GWB8-E makes our installation job even easier. It’s simple to connect with your radiator system and it’s available in nine sizes. That means you can install this boiler virtually anywhere in your house. Prefer not to use natural gas? No problem. The GWB8-E can be fueled by LP gas instead.2

Featuring most all the qualities we want to see in a boiler, the GWB8-E has it all: reliable parts, energy efficiency and dependability.
