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

Lennox GWB8-E BoilerThe Lennox® GWB8-E offers warmth at the times 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 really is that good.

Similar to our GSB8-E product, this boiler has an electronic ignition control that turns the burner on only 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, its 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. It’s easy to integrate with your radiator system and it’s available in nine sizes. That means you can install this boiler virtually anywhere in your home. Don’t want your boiler to use natural gas? No problem. 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: high-quality parts, energy efficiency and dependability. Call your Service Experts Heating & Air Conditioning in at 866-397-3787 to learn more or schedule a free appointment.
