GWB84-IE Boiler

Standard efficiency, gas-fired water boiler, with chimney or side wall venting

Offers an efficiency of up to 84.4% AFUE, meaning it can deliver energy savings compared to an older boiler. So even if winter brings its worst, you’ll stay comfortable without worrying about energy use. Up to 84.4% 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. Layers of thick fiberglass insulation minimize heat loss.
Includes extra attention to durability, with features like a cast-iron heat exchanger and corrosion-resistant burners.
If you have a traditional system, it will fit perfectly and provide precise heating comfort all winter long.

Electronic ignition control—monitors water temperature and maximizes efficiency by turning on the burner only when needed
Layers of thick fiberglass insulation—minimize heat loss

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
Titanium burners—provide greater resistance to corrosion and oxidation than competitive stainless or aluminized stell burners
Versatile installation—available in six sizes for installation virtually anywhere in the home, and can be fueled by natural or LP* gas
