Overview for Weil-McLain 386901006

Over the last 130 years, Weil-McLain has built a reputation of designing some of the most reliable boilers in the marketplace. Weil-McLain's Ultra hot water boiler is highly efficient, simple to install, and remarkably durable. Using condensing technology, the Ultra will reuse heat that escapes from conventional boilers, providing greater efficiency. When equipped with the optional Weil-McLain Advanced Features Module (AFM), the Ultra is a very user-friendly boiler. A clear display screen relays information about operations, temperatures, and system status. With AFM and an 87% AFUE, the Ultra UO-3 makes comfort and efficiency more accessible than ever before.
  • 3-Pass Heat Exchanger
  • The UO-3 uses a 3-pass cast iron heat exchanger. This design is more efficient and provides better flame control than non-3-pass designs, reducing your heating costs.
  • Venting Flexibility
  • UO-3 boilers can be placed into an existing chimney vent or direct vented. By using the direct vent exhaust gasses are simply piped out your home, no power-assisted fan needed.
  • Simple to Service
  • Another benefit of the 3-pass design is the horizontal configuration. With the swing-away door open, the UO-3 combustion area and flue are exposed for easy cleaning or maintenance.
  • 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.
  • Burner Options
  • Beckett NX, Beckett AFG, Carlin, Riello
  • Product Note
    This boiler does not include an oil burner. Please see the Accessories tab for compatible burners if you require one.

    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.

    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.

    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.

    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.

    DOE Heating Capacity 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 Learn More
    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.
