All necessary hot water boiler controls and secondary plumbing are in place and pre wired, and the vessels easily fit through a three foot wide doorway, resulting in a very quick start-up. Firing rates are available from 1100MBTU to 1700MBTU. However, many millions of BTU’s can be delivered by creating an efficient, fully modular system of many vessels operated by our control panel.

Standard features include nationally known parts and controls that are quickly available at most supply houses, allowing for easy quick and easy repair and maintenance, which can dramatically reduce down time.


Superior Boiler offers many options:

  • Choice of burner manufacturers fired by natural gas, oil, propane, or combination fuel.
  • Spark Ignition System for Combination Fuel Burners
  • Low-High-Low and Modulating gas trains
  • CSD-1, IRI, FM

The Series 1600 is manufactured to exceed ASME Section IV standards and will typically provide temperatures of between 160-210°F for space heating or process water applications. The vessel capacity is 109 gallons with a heating surface of 138 sq. ft. These vessels feature 70 vertical firetubes, each of which is 2″ diameter, 12 gauge steel and fitted with a high-efficiency turbulator for maximum heat transfer. The combustion chamber is fully water-backed, with burners that are UL listed.


A well-made, rugged vessel is naturally safer. Superior Hot Water Boilers also have a firebox design that is completely backed by water, along with safety controls on the boiler that results in a very safe and secure package.
