Thanks for the info
Do you see any visible leaks at all ..from the water pump.
Do you see any visible leaks around the heads or exhaust.
Do you have white smoke coming from the exhaust pipe.
Pull a couple of plugs and see if you can see coolant
Check your oil level .has it gone up and is milky
I don t think it is your thermostat as your car runs fine as long as you have coolant.
The same with your heater it blows cold due to lack of coolant.
You have to be losing coolant somewhere and you may have a blown head gasket. If you are losing that much coolant that quick it is either running out or going out the tail pipe.
Is the passenger floorboard wet?
Please let us know if what the final fix was for your car so we can better assist others. Thanks!
