Hot Water Boilers - Indoor Atmospheric / Natural Gas Fired

Rite Atmospheric Natural Gas Fired Watertube Boilers are found at the heart of better engineered closed-loop heating systems all over North America. From conventional space heating systems to heat pumps to industrial process loads, Rite offers 47 basic models, ranging from 480 to 12,499 MBH Input (11 - 300 Boiler Horsepower). These heavy duty, long lasting boilers have been providing heat to schools, churches, commercial buildings, metal finishers and silicone chip makers (to name a few) – Safely and reliably for over fifty years.

So simple to maintain and operate, Rite Boilers feature complete waterside access so that virtually all scale and mud deposits can be seen and mechanically cleaned during a single scheduled maintenance shutdown. The result – Better fuel efficiency and lower operating cost over the life of your boiler investment. Consider a few of our other standard features: Floating heads that eliminate pressure vessel cracks and broken welds caused by thermal stress cycling (backed by Rite’s 25 year Thermal Shock Warranty), Single Stacks on models to 7,500,000 BTUH input, Top supply and return water connections, Rugged Heat Exchangers with minimal pressure drop at normal flow rates are safe to operate at any flow rate. Rite’s bolted/gasketed headplates that eliminate any possibility of hydraulic explosion in the event that safety devices fail – and you have a better boiler by design.


Rite Atmospheric Boilers are an excellent choice when: Low NOx emissions are not required, natural gas or L. P. will be the only fuels used, and when lower combustion efficiencies at less than full firing rate are acceptable.

Atmospheric burners are far less expensive than power burners, so when the above criteria is met, then Atmospherics are a strong economical alternative to Rite’s outstanding line of power burner fired water boilers. Other factors favoring Atmospherics are: Extremely low electrical power consumption (no pre or post blower fan energy loss), Rapid start-up on demand (No pre-purge blower fan), Lighter weight, Lower height, and Whisper-quiet burner operation. For extra energy savings, specify automatic stack dampers and insulated head plates.
