Tankless water heater problem cycling on and off
My tankless water heater cycles on and off without any demand for hot water. It cycles on for about 10 seconds and then off. It does this 2-3 times an hour during the day and less at night. Any thoughts as to why this occurs and possible fixes?
Thank you

No idea. Problem w/ e.g. a flow sensor. I think that's what they use to decide you need hot water.

do you have a leak in the hot water line? Normally it's the flow sensor that turns on the heat, when nobody's home, take a look at your water meter and see if there's any water flow. A couple of heat cycles an hour is pretty radical.
