I was talking about a coolant leak. The coolant is inside the tank that is inside the AH box. Jeff had pictures of a corroded tank which is inside AH box. The mixing valve is located behind and under the burner. Either have long fingers and a mirror or remove the burner to gain access.

The blue tank is not involved at all with the AH.

As far as a fresh water leak....I would check the fittings around the burner area.
