    Burnham continues to be on the forefront of home heating technology. By constantly working to improve the efficiency of their boilers, they are able to pass the savings on directly to the homeowner. The K2-120 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 reliability. 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.
  • Sage2.3 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.
  • 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.
  • Included Taco Pump
  • The K2 includes a pre-installed high capacity Taco circulator pump, so you won't have to spend time and money finding one yourself.
  • Product Includes
  • (1) Burnham K2-120 K2 Hot Water Boiler
  • (1) Wall Mounting Kit
  • (1) Universal Exhaust Vent Termination Kit
  • (1) Miscellanous Parts Kit

General Information
Product Line
K2
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
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
Condensing
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 ? 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.
No
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. 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.
120000 BTU
Minimum Input Capacity
24000 BTU
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.
111000 BTU
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.
97000 BTU
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. Learn More
94 %
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. Learn More

Can I use the K2 for a radiant heat system in a driveway for snow melting?
Vance 
from Maryland 
October 19, 2015
Answer
The Burnham K2 Boiler can be used for a snow melting application with heat exchanger and appropriate anti-freeze. Running the fluid directly from the driveway to the boiler can be harmful and cause excessive thermal stress to the boiler.
+
Can this boiler be converted to LP?
Cindy 
from West Virginia 
October 05, 2015
Answer
Yes the K2 boiler can be field-converted for LP gas, and includes all the necessary labeling for the conversion. No additional parts are required, but your technician will need a combustion analyzer to make sure the burner is set-up properly for LP operation. Full instructions are available in "Appendix A: Instructions for Conversion of this Boiler for use with LP Gas" of the installation manual.
