Uniform Solar Hydronics and Geothermal Code 2021

The Uniform Solar, Hydronics and Geothermal Code is a model code developed by IAPMO to govern the installation and inspection of solar hydronic, and geothermal energy systems as a means of promoting the public's health, safety and welfare. Published previously as the Uniform Solar Energy Code, the 2021 edition adds significant provisions concerning hydronic and geothermal systems. USHGC was developed using the American National Standards Institute (ANSI)-accredited open consensus process.
