Just to share my idea ! Why I would like to place the bottle at the highest point :
1. In building service system, all expension tank is place at the highest point of the building
2. Easy monitor the flow yes or not.
3. Easy re-fill.
4. More easy to remove the air bubble from the system.
5. The bottle not require air tight (because under different operation temperature, water volume may various)
