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 and 85% thermal efficiency. 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.
