Tyring to add a WaterUse:Storage object to a model and noticed that in energyplus 8.8 the error file referred to the object as a WaterUse:Tank object which doesn't exist as an object in energyplus. Minor error but worth fixing.

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You are correct, the reference to a WaterUse:Tank object is likely out of date and should be updated to the appropriate WaterUse:Storage object.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.

Fixed for v8.9 here.
