    General Information
    Product Line
    Product Category
    Medium Learn More
    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.
    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.
    Natural Gas
    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.
    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.
    Chimney Vent
    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 Learn More
    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.

    Includes Pump
    Assembly Type
    AFUE Learn More
    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.

    Maximum Input Capacity Learn More
    Maximum Input Capacity
    The Maximum Input Capacity describes how quickly the appliance will use fuel when delivering it's maximum capacity. The units may change depending on the fuel being used.
    299 BTU
    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.
    185 BTU
    Ultra Low NOx Emissions Learn More
    Ultra Low NOx Emissions
    NOx is a byproduct of the combustion process, and it's output is regulated in some jurisdictions. Many regulators mirror SCAQMD rules, which regulate air quality for some parts of Southern California. Ultra Low NOx appliances emit less than 10-14 ng/J (nanogram per Joule) of NOx.
