The hot water heater sends hot water up to the shower under pressure, but when you are asleep, the pressureised water can't get back to the heater to stay hot, so it cools inside the pipeline. If you provide a real good polyurethane or fiberglass pipe insulation to the pipe from the water heater to the shower, you may solve the problem. but you'd have to tear open the walls to get to all the piping. You can simply turn on the hot water and let it run for eight minutes (or hopefully less) until the cold water is purged out, and the hot can then flow to you. The commercial method of fixing this problem is by recirculating the water even when the hot water is turned off. A small diameter tube is connected at the farthest hot water supply from the hot water heater, a small pump is installed, and the water that would be cooled by standing in the pipeline all night is continually returned to the hot water tank, and re-heated. Hotels use this practice so that you'll have hot water as soon as you turn on the tap. Homeowners consider this too expensive, and simply let the hot water get wasted down the drain until it turns warm.

Good Luck

: I have a fuel oil water heater. It has been inspected and appears to be in fine working order, except that the first shower of the morning is just barely warm enough. After that, the temperature is fine. We cannot turn up the thermostat because the water is almost too hot except for the morning. What could be causing this?
