Overachieving hot water circulator

I reviewed the historical data for my water heater as it is my #2 winter energy draw. I found on the power meter many reheats of the tank during the hours when no one is awake or using hot water. Further investigation showed my hot water recirculating pump ran intermittently at all hours – triggering frequent middle of the night reheats on the water heater. Simply setting the water circulating pump not to operate during times when we are asleep stopped the excessive middle of the night reheats. I now start the circulating pump one hour before we normally arise to ensure hot showers.

  1. Check my post from a few months ago about my circulating system. I have it tied to an HS110 Energy that I have tied to a routine in Amazon Alexa with their smart button. Basically the system is always off except when we go to take a shower, we hit the button which runs it for six minutes which gives us instant hot water at the shower.
