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 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 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 achieve nearly 84% AFUE, leading to more dollars subtracted from your monthly utility bills.

Installion is a breeze when it’s the GWB8-E. It’s simple to connect with your radiator system and it’s available in multiple sizes. That means you can install this boiler nearly anywhere in your house. Concerned about using natural gas? That’s fine. 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: reliable parts, energy efficiency and dependability.
