Overview for Burnham K2-180

Burnham continues to be on the forefront of home heating technology. By contantly working to improve the efficiency of their boilers, they are able to pass the savings on directly to the homeowner. The K2-180 is the next model in a history of state of the art, economical machines. The K2 line improves upon Burnham's condenser technology, allowing for optimal heating performance at up to 94% AFUE efficiency. The stainless steel body and included wall mount system allow for easy installation and long-term realiabilty. The K2 line also introduces the Sage2.3 system, providing high efficiency heating right out of the box, as well as an easy to use touch screen interface with intuitive menus and graphs. Burnham has strived to deliver the best, most efficient machines for residential heating, and the K2 continues that mission.
  • Sage2.2 Control System
  • The Sage2.2 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.
  • Built to be Efficient
  • The K2 line is designed to be easy to service, allowing for quick, efficient maintenance. Quicker maintenance combined with ease of installtion keeps initial and year-to-year costs down, saving money over the lifetime of the boiler.
  • Manage Multiple Boilers
  • The K2 boiler can be linked with other boilers, automatically communicating between each other to serve even the largest of spaces and efficiently heat your home. Using smart features, boilers work in tandem to share the load between all boilers.
  • High Altitude Boilers
  • Due to Burnham's condensing technology, the K2 model suffers little to no efficieny loss at higher altitudes. With an easily adjustable option built into the boiler, the the K2 model can work at near maximum efficiency up to 10,000 feet.
  • Multiple Installation Options
  • The K2 model comes with a built-in wall mount allowing for flexibilty in almost any installation situation. The K2's relativley small size and weight allow it to fit in nearly any space.
  • Domestic Hot Water
  • The K2-180 boiler can be adapted to also produce domestic hot water for you home. Using the easy to install K2 Instant Combi Kit (106341-01), the K2-180 can provide up to 4.4 gallons per minute at a 70 degree temperature rise.

    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.
    Hot Water
    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.
    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 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.

    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.

    18000 BTU
    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.
    167000 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.
    148000 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.
