The Board Of Boiler Rules met March 6 in Austin. The agenda is available online. The meeting was archived and is available for viewing on TDLR's web site.

TDLR proposes the repeal of all existing rules at 16 Texas Administrative Code (TAC), Chapter 65 and the proposal of new rules regarding the Boilers program. The proposed repeal is necessary to allow for rule simplification by adopting new rules that are better organized, easier to navigate and are in alignment with processes and procedures of the Department’s licensing, examination, certification and other boiler related activities.

The proposed new rules are necessary to replace existing rules, which have become cumbersome, dense and not well organized. The proposed new rules are also necessary as part of the Department’s agency wide effort to use plain language in Department rules, forms, letters and other communication. Read the rule proposal for more information.

On March 6, 2015, the Board of Boiler Rules met to consider the rule proposal published in the November 14, 2014, issue of the Texas Register (39 TexReg 8829). As a result of the March 6 meeting of the Board of Boiler Rules and the Department’s recommendations, the rules for consideration by the Commission during its May 6, 2015 meeting are available on the website (303kb PDF).

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.
