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 includes a cast iron heat exchanger and stainless steel burners created to avoid corrosion and oxidation1 and last for years. Effective heat year after year? It really is that good.

Similar to our GSB8-E product, this boiler has an electronic ignition control that only turns on the burner when it’s needed. Additional energy savings are possible with the GWB8-E’s thick fiberglass insulation and vent damper, which closes on its own when the boiler turns off. In fact, its efficiency ratings can reach nearly 84% AFUE, leading to reduced energy 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 home. Concerned about using natural gas? No problem. The GWB8-E can alternatively 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: high-quality parts, energy efficiency and dependability.
