Hello, my name is ***** ***** I look forward to helping you!What kind of water heater is it?
gas fired or electric?
Do you have thermometers mounted on the incoming and outgoing lines? There should be about a 20 degree temperature difference. That's Fahrenheit I'm in the states. If you are getting around that then its all good and just cold enough to need to run that often
If the temp difference is less than that then it shouldn't be running that often. If the difference is more then you should change the temps to get less heat loss.
