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

Lennox GWB8-E BoilerThe Lennox® GWB8-E offers heat just when you need it most. This boiler includes a cast iron heat exchanger and stainless steel burners created to prevent corrosion and oxidation1 and last for years. Consistent heat year after year? It’s just as sweet as it sounds.

Similar to our some of our other products, this boiler has an electronic ignition control that starts the burner only when it’s needed. Additional energy savings are possible with the GWB8-E’s thick fiberglass insulation and vent damper, which closes on its own when the boiler turns off. In fact, this boiler’s efficiency ratings can reach nearly 84% AFUE, leading to reduced energy bills.

Installion is a breeze when it’s the GWB8-E. We can easily integrate it with your radiator system and it’s available in nine sizes. That means you can install this boiler virtually anywhere you want. Don’t want your boiler to use 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.
