  • Demand controlled recirculation systems:  Eliminate the wait for hot water in any plumbing system by using on-demand recirculation pumps.  Works with any tank, tankless, or heat pump water heater, in any plumbing configuration

  • Temperature modulation controls: Turn any commercial water heater or boiler into an economizing smart system that reduces fire time and saves energy

  • Remote monitoring: View your hot water system performance data in real time and analyze historical trends.  Set up alert notifications to tell you when there are system failures or remind you of preventative maintenance schedules

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.

Proud partner of the US Department of Energy Zero Energy Ready Home program

A DOE Zero Energy Ready Home is a high performance home that is so energy efficient that a renewable energy system could offset most or all of the home’s annual energy use.  AutoHot meets the program requirement for demand based controls for hot water recirculation pumps.
