Overview for Weil-McLain P-WTGO-4

Overview for Weil-McLain 386700833Over 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 Features
Simple to ServiceInspecting 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 SealsSilicone-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 FlexibilityWTGO 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 InsulationHeat 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 PackageSatisfying 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-4 does not inflate the size of the unit; it enjoys the same compact size as comparable Weil-McLain WGO boilers.

    Medium Learn More
    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 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.

    DHW Production Learn More
    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.

    AFUE Learn More
    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.
