Standard efficiency, gas-fired water boiler with chimney venting
Here are some of the top features of the GWB84-E:
With 84% of fuel converted into usable heat, you can enjoy a comfortably warm home all throughout the winter, without worrying about energy use.
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. Layers of thick fiberglass insulation minimize heat loss and on-off cycling. Factory-installed safety switch protects against potentially dangerous low-water conditions. An automatic vent damper closes when it shuts off, preventing wasted heat.
The heat exchanger at the heart of this boiler is also designed for durability, over a range of water flow rates. Burners are made of stainless steel for greater resistance to corrosion and oxidation.
Electronic ignition control—monitors water temperature and maximizes efficiency by turning on the burner only when needed
Thick fiberglass insulation—minimizes off-cycle heat and energy loss
Vent damper—automatically closes when the boiler turns off, maintaining energy efficiency
Easy integration—works with traditional radiator systems to provide precise heating comfort, regardless of outdoor temperatures
Cast iron heat exchanger—designed for years of long-lasting reliability
Versatile installation—available in nine sizes for installation virtually anywhere in the home, and can be fueled by natural* or LP gas
Stainless steel burners—provide greater resistance to corrosion and oxidation**
