Bill,
Are you saying the temp of the coolant lines to the fan coils are very hot but the line from the tank to the mixing valve is always less than 100 degrees F? The two lines to test for temperature are the output line from the tank to the mixing valve (should be very hot as indicated by Steve) and the output line from the mixing valve to the coach (should be at set point temp of about 120 degrees F).
It helps if the incoming cold water is at 60 degrees F or more but that line is not a part of testing the valve for proper operation. It only impacts the output temp if 55 degrees F or cooler.
The Aqua Hot is rated at 55 degree F temp rise at a flow rate of 1.5 gallons per minute. Most shower heads meet this flow rate and water from the coach tank usually is warm enough to allow for a hot shower.
Asking Roger on the Aqua Hot forum is another excellent resource too. He is the very best.
Hope this helps you.
