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

Lennox GWB8-E BoilerThe Lennox® GWB8-E offers 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 really is that good.

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 by itself when the boiler turns off. In fact, its efficiency ratings can achieve nearly 84% AFUE, leading to a decrease in your 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 a variety of sizes. That means you can install this boiler almost anywhere in your home. Don’t want your boiler to use natural gas? That’s fine. The GWB8-E can alternatively be fueled by LP gas instead.2

Containing three qualities we want to see in a boiler, the GWB8-E has it all: well-made parts, energy efficiency and dependability.
