I had a hot water loop installed with a pump, timer & check valves. Since the system has been activated, hot water temperatures run from 10 to 20 degrees cooler when the pump is running than when it is off. The plumber tells me this is normal and to compensate, I should raise the thermostat on my hot water tank high enough to attain a comfortable hot water temperature when the pump is running. Won’t this increase energy costs for hot water? Are his explanations correct or his he making excuses to avoid correcting a mistake? He supposedly checked for cross connections and didn’t find any. any help or suggestions are welcome.

Why the timer you need a water temp sensor in the system this will activate the pump when water temp drops and will shut off when sensor is satisfied. I just installed such a system in my own home had a problem with the sensor I originally purchased it was a surface mounted unit a diden't work woth a s--- . I posted this on the board got a lot of ideas but purchsaed a sensor ($85) from a Taylor hot water dealer that went directly into the water and it works like a champ pump runs only once in a blue moon and is quite. There were some very good ideas sent to me from break time but I was already finished so maybe the next one. The one idea that really impressed me was where they ran one inch out to the far end and them dropped down to 1/2 inch pipe ifyou are higher than your water heater you would get a gravity effect, however I have a 100 foot ranch and happy with the present system call the plumber back and tell him your not happy with the system
