IAPMO Releases 2026 Code Meeting Monographs for Solar, Hydronics and Pool Standards
Key Highlights
- 2026 technical monographs released ahead of May ANSI code development meetings
- Proposed updates span solar, hydronics, geothermal and aquatic system standards
- Industry stakeholders encouraged to participate in consensus-driven code development process
ONTARIO, CA — The 2026 Uniform Solar, Hydronics and Geothermal Code (USHGC®) and Uniform Swimming Pool, Spa and Hot Tub Code (USPSHTC®) technical committee meetings will be conducted virtually, and attendees must register in advance. Registration details can be obtained by contacting [email protected].
IAPMO® has made both Technical Committee Meeting Monographs available for download:
USHGC: codes.iapmo.org/docs/2027/USHGC/2026_USHGC_TC_Meeting_Monograph.pdf
USPSHTC: https://codes.iapmo.org/docs/2027/USPSHTC/2026_USPSHTC_TC_Meeting_Monograph.pdf
Hardcopy versions will not be available at the meetings.
Proposed Updates Span Solar, Hydronics and Geothermal Systems
Topics under consideration for the USHGC include updates related to heat transfer fluids and chemical compatibility, freeze protection strategies, auxiliary heating systems, potable water protection and backflow prevention, and piping system materials and connections.
Additional proposed areas include indirect-fired domestic hot water systems, ground source heat pump installation practices, subsurface testing and site evaluation, system commissioning and labeling, and qualification standards for designers and installers.
Aquatic System Standards Also Under Review
Proposed changes to the USPSHTC cover a wide range of aquatic facility topics, including water chemistry parameters, oxidation reduction potential (ORP), finishes and surfaces, and turnover time requirements.
Other areas include construction safety measures such as fencing and barriers, as well as design and operational standards for pools, spas and specialty aquatic venues such as wave pools, surf pools, artificial lagoons, float tanks and aquatic play features.
Industry Participation Encouraged in Code Development
IAPMO encourages active participation from installers, inspectors, engineers, manufacturers and other industry stakeholders in the consensus development process.
The organization emphasizes that collaborative engagement helps ensure that the Uniform Codes continue to support public health, safety and welfare through fair and balanced standards development.
