water dispenser / cooler

Office workers would prefer not to lift and change the water bottles. Looking for examples I found the possible solution:


However, even this model can be improved. My proposal

Usually we tend to keep several bottles at a time. Here we have 4 bottles model, like a double door fridge it opens allowing to load all at once (will be done by delivery man), he attaches the yellow plugs which dispense all bottles. Between the round bottles there is a gap where cooler motor and heater located (dark blue and red). The spare water container is between the bottles (purple). The taps are on the door.
The overall design is compact, allow to use top of the cooler, hide spare bottles, uses all of them at once.

I believe there should be one more useful function - WiFi internet connection and order button. Once connected it would be enough to press to order (or the water counter will order the new water itself).
