Arizona Hot Water Boilers are a range of pressurised steel boilers suitable for use with forced draft air burners running on diesel, oil or gas.

The Arizona Hot Water Boiler is a high output boiler made entirely of carbon steel to allow it to operate at different powers within a set range. Arizona Hot Water Boiler is a scotch marine boiler featuring three combustion gas passes. The cylindrical combustion chamber has a wet back, which improves heat exchange between the combustion gases and the water. The front door is lined with specially shaped firebrick to make it easier for the combustion gas to enter the tubes. The combustion gas passes through the tubes at very high speed and turbulence, and into the rear smoke chamber. The turbulence is accentuated by specially designed turbofans that help increase heat exchange.
