Building Energy Code Requirements

Central to a high performing hot water system is a demand-controlled recirculation pump. Building energy codes and performance certifications are now requiring that buildings that use hot water recirculation pumps must also have demand controls to help regulate the system run time for reduced energy losses. Using and specifying the AutoHot system will help your building meet these code requirements and ensure efficient hot water delivery in any application. Look for these requirements in such new building standards such as: California Title 24 (part 6), International Energy Conservation Code (IECC), The Department of Energy Zero Energy Ready Home (ZERH) program, LEED for Homes v4 and others.
