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

Lennox GWB8-E BoilerThe Lennox® GWB8-E offers heat just when you need it most. This boiler includes a cast iron heat exchanger and stainless steel burners designed to resist corrosion and oxidation1 and last for years. Reliable heat year after year? It can’t get much better than that.

Similar to our some of our other products, this boiler has an electronic ignition control that starts the burner only when it’s needed. Energy savings are maximized with a 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 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 multiple sizes. That means you can install this boiler almost anywhere you want. Prefer not to use natural gas? That’s okay. The GWB8-E can be fueled by LP gas instead.2

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