Cold water from Aqua Hot

[Richard and Rhonda]

I had a little issue with the hot water from the Aqua Hot not being hot. I knew the unit was operating at temp from the Aqua Hot temperature gauge and the fact the heater vents were blowing nice hot air.

I had this problem since I bought the coach.

A little investigation shows that inside the cover of the Aqua Hot is a mixing valve that adds cold incoming water to the hot outgoing water to control the temp of the outgoing hot water. Voila'. I had to get the Webasto burner unit out of the way to access it, but adjusment was simple after that.

I am pretty sure the original owner had small children, and I suspect the hot water temp was turned down on purpose.
