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

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

Similar to our GSB8-E product, 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, its 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. 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. Prefer not to use natural gas? That’s fine. 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.
