Lennox GSB8-E Gas-Fired Steam Boiler – Efficient in every possible way

• An electronic ignition allows the GSB8-E to turn on only when heat is needed.
• An automatic vent damper closes when the GSB8-E shuts off, preventing wasted heat.
• Layers of thick fiberglass insulation minimize heat loss and on-off cycling.

Durable, dependable comfort
Long life and reliable operation are part of the GSB8-E’s design. That’s why it uses a cast-iron heat exchanger, titanium burners and an automatic low-water cutoff switch.

Versatility that’s always a perfect fit
The GSB8-E works with your home’s existing radiator or under-floor heating system, and is available in 7 different sizes for a perfect fit nearly anywhere in your home.

Choose your fuel source 
The GSB8-E can use either LP gas or natural gas safely and efficiently. So you can choose whichever fuel is most cost-effective in your area.
