HH hot water question

I've noticed that when I leave the Hydro Hot electric element on over night, in the morning, the water coming out of the kitchen faucet in the cold position is quite warm for 15 or 20 seconds. Any thoughts on how this could be??
Thanks.

Could be the cold feed line is routed next to the HH heater line for a short distance, and the initial call for cold water clears that radiated heat.

Check the hot and cold water valves on your outside shower and make sure they're turned off. Some folks turn the water off at the shower head and leave them on. If you do, it provides a path for the hot water to naturally convect through the facet to the cold water side and begin to fill the cold water pipes with hot water.

OK Ron, I'll bite. So do you mean that in addition to the actual faucets in the utility compartment, there are on/off valves on the hot and cold lines? I assume they would be soemwhere behind the panel. Can they be reached when that center panel is removed?
Thanks.

David:

Ron is talking about the shower head faucet in the utility bay. Some folks turn the dial on the shower head itself off, but fail to turn off the hot and cold handles. The heat then travels into the cold water side.

I would never make that mistake. My shower head leaks like a sieve when off, but now it doesn't even slow the water down. One of these years I might even remember to replace the thing.

Gotcha - I don't even have the hose and "faucet" attached. I'll make sure the knobs are snugged down.

David - depending on which model HH unit you have, will determine how the tank hot water lines are run. Some tanks had the copper line wrapped around them, and some actually have a heat exchanger inside the tank. We sometimes get the same thing, but we turn the element off during the night why waste the electricity, and it about 10 minutes before it's hot again, as the system holds heat quite well all night long, now if you are also using the element for heat for the coach, then that is another story. I would not worrry about it, is' normal for ours.
