What is a Boiler?

Equipment that falls within the scope of the Texas Boiler Law and Rules, that must be registered and inspected, is defined in both the law and rules. This means all types of boilers that are used in commercial and public facilities that produce steam (either low or high pressure), hot water heating for use in comfort air heating systems, and hot water supply for use in domestic water systems (such as showers, sinks, pools, or for miscellaneous use) which includes potable hot water heater type boilers. Boilers used for hot water supply or potable hot water supply can be further defined in the following two (2) categories:

  • A hot water supply boiler means a boiler designed for operation at a pressure not exceeding 160 psig or temperatures not exceeding 250 degrees Fahrenheit at or near the boiler outlet if the boiler's: heat input exceeds 200,000 BTUs per hour; water temperature exceeds 210 degrees Fahrenheit; or nominal water-containing capacity exceeds 120 gallons.
  • A potable water heater means a boiler designed for operation at pressures not exceeding 160 psig and water temperatures not exceeding 210 degrees Fahrenheit if the boiler's: heat input exceeds 200,000 BTUs per hour or nominal water-containing capacity exceeds 120 gallons.

Further classification and definitions can be obtained by accessing the Texas Boiler Law and Rules and referring to the definitions in both the law and rules or by calling (800) 722-7843 and a technical representative can assist you with any questions.
