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

Lennox GWB8-E BoilerThe Lennox® GWB8-E provides warmth effectively when you need it most. This boiler features a cast iron heat exchanger and stainless steel burners designed to avoid 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 turns the burner on only when it’s needed. Additional energy savings are possible with the GWB8-E’s thick fiberglass insulation and vent damper, which automatically closes when the boiler turns off. In fact, this boiler’s efficiency ratings can achieve nearly 84% AFUE, leading to more dollars subtracted from your monthly 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 multiple sizes. That means you can install this boiler virtually anywhere in your home. Concerned about using natural gas? That’s okay. The GWB8-E can alternatively be fueled by LP gas instead.2

Having many of the qualities we want to see in a boiler, the GWB8-E has it all: high-quality parts, energy efficiency and dependability.
