Available in 7 sizes from 500 to 2000 MBH, Pennant boilers and water heaters run reliably on natural or LP gas and deliver efficiency levels up to 85%. Pennant systems are also among the “greenest” in the industry with NOx emissions below 10 ppm.




      The Mighty Therm2 has been specifically designed to meet the needs of the replacement market by offering simple and straightforward controls with 2-stage firing.

      Mighty Therm2 boilers and water heaters feature convenient, modular construction that separates the burner trays, gas train, and blower assembly. All models use lightweight insulation, glass-lined cast iron or bronze headers, and non-ferrous waterways. The 10 tube heat exchanger design uses finned tubing for the quickest and most efficient heat transfer.
