I don't know about the overflow bottle not working, but there is plenty here to start your troubleshooting:

Good Luck!

A failing radiator cap will cause water to not transfer to the radiator. Hearing the water rush into your heater core suggests you have a water leak in the system, which will also cause the overflow to not flow back to radiator.

Yeah, if you have a small leak and it takes less pressure to force the water out of the leak spot than it does to open the rad cap, then the rad cap will never open and you will be losing water. So check for leaks, rebleed the system and check the rad cap. You might want to get a new cap, they aren't much money and worth it to prevent any other cooling problems.
