Learn how this no-cost rebate opportunity can improve your building’s energy efficiency, lower operational costs, and enhance sustainability.

How The Temperature Modulation Controllers Work

The Temperature Modulation Controller automatically adjusts the water temperature based on hot water demand at your multifamily property.

During peak periods of hot water use (e.g. daytime) your water heater or boiler remains at its existing set-point temperature. During low/no periods of use (e.g. late at night) the controller automatically resets to a slightly lower temperature, matching heating capacity to demand, and saving energy.

If there is a demand for hot water, your water heater or boiler will heat to precisely the correct temperature no matter what time of day or night.

Remote Monitoring Features​

  • Monitor your system remotely. As an optional no-cost or subscribed service, the AutoHot Temperature Modulation Controller can connect to a Wi-Fi network and provide remote access to your hot water system data. Get notified of potential hot water system issues before tenants find out the hard way!
  • Remote Monitoring is not contingent on receiving a controller. You have the option of not having this service provided given you do not have a signal or have opted out. You will still benefit from the AutoHot saving your property each month on your monthly gas bill.

Eligibility Requirements

In order to have AutoHot provide and install a Temperature Modulation Controller, the multifamily building must have the following:

  • A central water heating system (water heater or boiler) servicing no less than two dwelling units. (Individual water heaters inside the units do not qualify).
  • You must have a SoCalGas bill that shows the Master Meter or Central Number of Facility Living Units on the invoice.
  • Multifamily Buildings cannot have received this same type of controller over the last five years.
