Features
Features
    Over the last 130 years, Weil-McLain has built a reputation of designing some of the most reliable boilers in the marketplace. Their dedication to producing lasting heating solutions is seen in every boiler they make. The WGO is a flexible, durable, oil-fired heating solution for hot water systems. Efficient energy use is a high point of the WGO's design, allowing you to make the most of your energy dollar. Weil-McLain knows the value of longevity, so they used cast-iron for WGO boiler sections. Between the high efficiency, durable construction, and flexibility, the WGO excels both as a replacement boiler and as an addition to new construction.
  • Simple to Service
  • Inspecting and maintaining a WGO is incredibly simple. Between the swing-away burner door and the quick-open top panel, the WGO is always accessible. Weil-McLain uses a recessed target wall design to protect the unit from flue brushes during cleaning.
  • Captured Seals
  • Silicone-coated fiber ropes are used for sealing the boiler sections. These seals expand and contract with the boiler, keeping the unit watertight and preventing contaminants from entering your system.
  • Venting Flexibility
  • WGO boilers have two vent connections, one on the rear and one on the top. By providing an alternate venting set up, Weil-McLain has ensured that the WGO is suited for a variety of installation conditions.
  • Efficiency-Boosting Insulation
  • Heat retention is critical to energy efficiency. Heat leakage represents energy use without any comfort gains. An extended, insulated steel jacket prevents heat from escaping the WGO and improves the efficiency.
  • Product Includes
    • (1) Weil-McLain WGO - Section Assembly (386700656)
    • (1) Weil-McLain WGO - Jacket (416700172)
    • (1) Weil-McLain GO - Collector Hood (450020189)
    Product Note
    This is a knockdown containing a boiler section assembly, jacket, and collector hood. Trim and a burner are required for installation.

Cast Iron
Fuel Type Learn More
Fuel Type
To create heat, some form of fuel is required. Fuel Type specifies what the product uses as an input to create heat.
Oil
Combustion Type Learn More
Combustion Type
Condensing appliances use leftover thermal energy from combustion gases to heat water in a secondary heat exchanger, resulting in higher efficiency and lower exhaust temperature.
Conventional
Vent Type Learn More
Vent Type
Products that use combustion (burning) of fuel to create heat also create potentially dangerous gasses that need to be exhausted (AKA "Vented"). Depending on the product, venting can be done via a chimney, through a side wall, or use a second vent to provide fresh air to the appliance.
