I have an electric water heater in an unheated basement.
The water runs through about 20 feet of 1/2" copper pipe
before it gets to my kitchen sink faucet.
Here's my mystery;
The HOT water is a lot hotter in the summertime.
Now, I know that the waterheater/thermostat doesn't care
whether its summer or winter.......
and the temp in the tank is probably constant.
Is there be that much ( winter ) heat loss in 20 feet of copper pipe ?
Also, there is the fact that your cold water inlet is much warmer in the
summer. So if you use to a specific setting of cold/hot mix, the water will
overall seem much hotter in the summer.

Sorry to rain on the parade but unless the basement is open to the
outside, the temp from summer to winter won't change very much, not
enough to noticeably effect the heat loss through the pipe. Also, the
incoming water supply will be the same temp winter/summer and the temp
of water into the tank has -no- effect on how hot the water gets in
the tank. IMO Jim has it right, it is only a incorrect subjective
impression. If it truely does vary, there will be some other
explanation than temperature variation in the basement or water

Harry, I've actually checked my water temp at the tap using a
thermometer and it gets down to about 55 degrees in winter and 65+ in
late summer. This is in the Detroit area, which might have more
variation than other systems.
