    The KNIGHT modulating-condensing heating boiler has consistently delivered everything the professional needs for ease of installation and maintenance, and everything homeowners need for total comfort and long-term savings on energy costs. Now, with 10 floor-standing models and 5 compact Wall Mount units, Lochinvar offers the industry’s broadest selection of  modulating-condensing heating boilers. And KNIGHT is the industry’s most advanced boiler design, including the SMART SYSTEM™  operating control that has quickly become a legendary benchmark among the trade!  For traditional space heating or radiant floor heating applications, KNIGHT offers your customers tremendous savings on energy costs compared to less efficient boilers. KNIGHT has earned the ENERGY STAR, signifying that it has met strict energy-efficiency guidelines set by the EPA and U.S. Department of Energy.
     
     
    The KNIGHT Heating Boiler is an appliance that compliments the house. Refrigerators, stoves and dishwashers hold this distinction; and yes, even water heaters are starting to. So why not your major heating appliance? Contractors today take great pride in the appearance of piping and control systems used in residential heating. Why shouldn’t the boiler be appealing as well? The KNIGHT Heating Boiler uses a sculpted steel jacket which gives the contractor the ability to provide their customer with a professional installation.
    The jacket is not an integral part of creating the sealed combustion aspect of this appliance. The KNIGHT Heating Boiler uses a direct air intake connection to the combustion air inlet fan. This eliminates the need of a sealed outer jacket assembly and makes service to the boiler much easier. Leveling legs are provided as standard equipment allowing for a professional, clean installation on uneven floors. Panel removal for service and setup is made easier with the KNIGHT Heating Boiler jacket. The top and front panels utilize snap pins that hold them firmly in place. To access the interior, simply pull the panels off by hand.

    The Burner

    The burner used in the KNIGHT Heating Boiler is 411stainless steel. The burner is in a 360 degree configuration and covers the entire length of the primary heat exchanger allowing for substantial reduction in the overall size of the appliance. Units that utilize multiple burners are generally much larger in size

     
     
    The Heat Exchanger  

    The KNIGHT Heating Boiler’s heat exchanger is an advanced design. Its construction is of 316L stainless steel tubes, headers and casing. Stainless steel heat exchangers perform without constant monitoring of the system pH. The tubes are welded into headers eliminating the need for any gaskets or O-rings. The tubes are oblong and formed utilizing an advanced hydro forming process. Hydro forming uses pressurized water exceeding 10,000 psi to alter the shape of the stainless steel tube. This easily creates the desired tube shape.

This easily creates the desired tube shape. 
    The heat exchanger appears to be one single unit when it is in fact two heat exchangers in one - the primary heat exchanger, which is exposed to the burner flame; and a secondary heat exchanger, which is only exposed to the flue gas.  The KNIGHT Heating Boiler is a condensing boiler that allows condensation to occur only on the secondary portion of the heat exchanger. This design allows for entering water temperatures to be as low as 50°F thus eliminating worry of damage to the primary heat exchanger. 
    The heat exchanger is ASME Section IV approved and is marked with an “H” stamp indicating ASME compliance. ASME approval for a pressure vessel is important. ASME ensures the user and installer of the highest quality in design and materials possible for the heat exchanger.
