    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 SGO is a flexible, durable, oil-fired heating solution for steam systems. Efficient energy use is a high point of the SGO's design, allowing you to make the most of your energy dollar. Weil-McLain knows the value of longevity, that's why they used cast-iron for SGO boiler sections. Between the high efficiency, durable construction, and flexibility the SGO excels both as a replacement boiler and as an addition to new construction.
  • Simple to Service
  • Inspecting and maintaining a SGO is incredibly simple. Between the swing-away burner door and the quick-open top panel, the SGO 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
  • SGO 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 SGO and improves the efficiency.
  • Product Note
    This boiler does not include an oil burner. Please see the Accessories tab for compatible burners if you require one.

Medium Medium refers to the substance that carries heat through the heating system. Systems are either designed to use either Hot Water or Steam as a medium, and components are usually specific to one or the other.
Steam
Heat Exchanger Material
Cast Iron
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
Conventional
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.
Chimney Vent
DHW Production DHW (Domestic Hot Water) is potable water for uses other than space heat. Some boilers are able to provide DHW "out of the box", while others can do so with the purchase of optional accessories.

Modulating/Staging Stages are unique speeds or levels that equipment can operate at. More stages allow for better fine-tuned control of output, which improves comfort and efficiency. Modulating equipment can operate across a range of levels, giving the highest level of fine-tuned control. Learn More

Can you use an indirect hot water heater with this boiler?
Anthony 
from New Jersey 
October 24, 2015
Answer
The SGO boilers can be used with indirect-fired water heaters. Instructions can be found on page 18 of the installation manual, which you can access on the manuals tab or here. Weil-McLain also offers a tankless water heater kit that can be used with SGO boilers.

Thanks for your question!
