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 designed to prevent corrosion and oxidation1 and last for years. Effective 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. It further maximizes energy savings with a thick fiberglass insulation and vent damper, which automatically closes when the boiler turns off. In fact, the GWB8-E’s efficiency ratings can achieve nearly 84% AFUE, leading to reduced energy bills.

The GWB8-E makes our installation job even easier. It’s simple to connect with your radiator system and it’s available in nine sizes. That means you can install this boiler nearly anywhere in your house. Prefer not to use natural gas? That’s okay. The GWB8-E can also 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: well-made parts, energy efficiency and dependability.
