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 WTGO is a flexible, durable oil-fired combi boil. In the WTGO, Weil-McLain has taken their exceptional WGO design and added a tankless coil for water heating, making the WTGO an inclusive heating solution. Efficient energy use is a high point of the WTGO'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 WTGO boiler sections. Between the high efficiency, durable construction, and flexibility the WTGO excels both as a replacement combi boiler and as an addition to new construction.
  • Simple to Service
  • Inspecting and maintaining a WTGO is incredibly simple. Between the swing-away burner door and the quick-open top panel, the WTGO 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
  • WTGO 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 WTGO 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 WTGO and improves the efficiency.
  • Dual Purpose, One Small Package
  • Satisfying your space heating and DHW needs does not need to take up a lot of space. The tankless water heater included with the P-WTGO-5 does not inflate the size of the unit; it enjoys the same compact size as comparable Weil-McLain WGO boilers.
  • Product Note
    This boiler does not include an oil burner. Please see the Accessories tab for compatible burners if you require one.

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.
