Sounds like classic head gasket symptoms i'm afraid :(

But try checking your radiator and thermostat, make sure the radiator isn't all bent up (fins) and test the thermostat by following the guide on this forum.

More like classic waterpump failure unless you did only have water in the system instead of coolant and it has frozen...
For the heaters to remain cold when the engine is overheating there can't be any coolant circulating.

How long did it take you to drive those 3-miles before it over-heated?

For it to overheat in 10-minutes, it is unlikely to be the thermostat.

Hi its Possibly the waterpump, maybe its wheel has dropped off.But i would still be inclined to undo the rad bleed screw to see if water comes out.If you have had no water loss then its odd.

When the engine is running, is there coolant flowing through the small pipe into the expansion tank?
You should be able to clearly see the coolant flow.

Coolant should flow though that small pipe all the time the engine is running.
The thermostat just stops the flow to the radiator.
