Features
- 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 WTGO does not inflate the size of the unit; it enjoys the same compact size as comparable Weil-McLain WGO boilers.
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.
Product Note
This boiler does not include an oil burner. Please see the Accessories tab for compatible burners if you require one.

Medium
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.
Hot Water
Heat Exchanger Material
Cast Iron
Fuel Type
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
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
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.

DHW Production
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
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

AFUE
AFUE
AFUE (Annual Fuel Utilization Efficiency) measures the efficiency of combustion equipment over the entire heating season, and is calculated by dividing the amount of energy that is actually heating your home by the total energy contained in the fuel used by the boiler/furnace. Learn More

DOE Heating Capacity
Also referred to as Gross Output, this is the output of a boiler after accounting for combustion efficiency. We recommend sizing hot water boilers based on the DOE Heating Capacity.

Net I=B=R Capacity
I=B=R, also referred to as Net Output or AHRI Capacity, is the rated heat output of a boiler after accounting for combustion efficiency, piping loss, and an extra pickup factor. We recommend sizing steam boilers based on the I=B=R rating.
