GSB8-E Boiler

Standard efficiency, gas-fired steam boiler

Up to 82.7% of fuel is converted into usable heat.
An electronic ignition allows it to turn on only when heat is needed, and reduces the possibility for the flame to go out like a standard pilot light.
An automatic vent damper closes when it shuts off, preventing wasted heat. Layers of thick fiberglass insulation minimize heat loss and on-off cycling.
Factory-installed safety switch protects against potentially dangerous low-water conditions.
This boiler works with your home’s existing radiator or under-floor heating system.

Electronic ignition—burns fuel only as necessary, reducing energy costs
Thick fiberglass insulation—minimizes off-cycle heat and energy loss
