Boiler and Pressure Vessel Safety Inspections

Boilers and pressure vessels are governed by Iowa Code Chapter 89 as amended by House File 368. 

The Iowa Division of Labor regulates boilers and pressure vessels, including many hot water heaters.  Hot water heating boilers used exclusively for pools or spas are under the jurisdiction of the Iowa Department of Public Health. 

Ten-day notice of new installations must be provided pursuant to Iowa Code Section 89.6.  Click here for a 10-day notice form.  Certain repairs and alterations must be authorized in advance by an authorized inspector.  Covered objects must be inspected by state inspectors or authorized insurance company inspectors.
