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

Lennox GWB8-E BoilerThe Lennox® GWB8-E provides warmth just when you need it most. This boiler uses a cast iron heat exchanger and stainless steel burners created to resist corrosion and oxidation1 and last for years. Effective heat year after year? It can’t get much better than that.

Similar to our GSB8-E product, 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 automatically closes when the boiler turns off. In fact, the GWB8-E’s efficiency ratings can achieve nearly 84% AFUE, leading to more dollars subtracted from your monthly utility bills.

We’re already experts at boiler installations, but the GWB8-E makes our job more simple. We can easily integrate it with your radiator system and it’s available in nine sizes. That means you can install this boiler almost anywhere you want. Don’t want your boiler to use natural gas? No problem. The GWB8-E can alternatively 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.
