Overview for Burnham K2WTC-180B-6T02

The Burnham K2 Combi is a high efficiency condensing combi boiler working as a hydronic boiler and tankless water heater. With a 10:1 turn down ratio and a variable speed combustion blower, the K2 Combi is incredibly efficient, reaching an AFUE rating of 95%. The K2 Combi line also introduces the Sage2.3 boiler control system with easy setup and high performance right out of the box.
  • Heating and Hot Water Production
  • The K2 Combi combines domestic hot water and space heating, all in an efficient 95% AFUE package. This unit can provide 4.5 gallons per minute at a 70 degree temperature rise.
  • Sage2.3 Control System
  • The Sage2.3 system has a simple touchscreen interface built into the boiler. The system provides step-by-step instructions for changing settings and running system diagnostics, making the K2 one of the most user friendly boilers on the market.
  • Compact Design
  • A compact and versatile design allows the K2 Combi boiler to be wall hung with the pre-installed bracket and wall mount kit, keeping the K2 Combi up and out of the way.
  • Outdoor Reset
  • The K2 Combi increases efficiency by including an outdoor sensor, allowing the boiler to lower water temperatures when the outdoor temperatures are warmer.

    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.

    Stainless Steel
    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.
    Condensing
    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.
    Direct 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
    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.

    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.

    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.
