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. Reliable 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. It further maximizes energy savings with a thick fiberglass insulation and vent damper, which closes on its own when the boiler turns off. In fact, this boiler’s efficiency ratings can add up to nearly 84% AFUE, leading to more dollars subtracted from your monthly utility bills.

The GWB8-E makes our installation job even easier. We can easily integrate it with your radiator system and it’s available in a variety of sizes. That means you can install this boiler nearly anywhere you want. Prefer not to use natural gas? That’s okay. The GWB8-E can 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: well-made parts, energy efficiency and dependability.
