I have a 2003 Bounder 35R with the Atwood gas-electric water heater. The temperture of the water at the heater is 140. The temperature of the water at the kitchen sink is 115. The thermostat has been checked and is functioning normally. How am I losing 25 degrees of heat?

bounderman,
Welcome to irv2 Check your bypass valve on your HW heater,an make sure your outside shower valves are closed. If they are open a little bit will cut water temp. If your HW water temp is to high good way to adjust with bypass valve.---"007"
The bypass valve is in the normal operating position. The outside shower valves are completely closed. I used air this AM to blow out the system. It produced some black junk in the shower stall but it did not help.
Another thing that can allow cold to mix with hot in the system is shutting the shower off at the head while leaving the hot/cold taps open.
How long a run is it from the tank to the tap where you measure 115? It's just plastic pipe and probably does indeed lose a lot of heat along the way. I wouldn't expect a 25 degree drop, but...?

Please allow me to munch on some of my own words. After asserting that the valves on the outside shower were in the off position, I went back and double checked. The cold water was not completely off. After closing the valve, the hot water returned. A huge thank you to 007. You saved my tail.

My thanks to you bounderman, for bringing this to our attention, some of us have done the same thing, forgot about Garys inside shower, any newbe will remember your post also. I have used the hot water bypass as a mixer to cut down the water temp in some MH's. Happy Travels ---"007"
