Good catch!
You are correct, the reference to a WaterUse:Tank object is likely out of date and should be updated to the appropriate WaterUse:Storage object. Maybe @MJWitte or @JasonGlazer can weigh in.
What this error message is really saying is that you may have a storage tank, but you haven't defined a WaterUse:Connections object to define what water draws the storage tank should try to meet. The water use connections object is really a grouping of WaterUse:Equipment objects that define the individual water draws.
The name of the storage water tank -- "Hot Water Tank" -- should be referenced by the Supply Water Storage Tank Name or Reclamation Water Storage Tank Name input fields, depending upon what role the storage tank plays in the water system.
