Not to discount anything, whats easiest is often the problem.
When the Heater is not working when the engine is warm, it usually means low radiator fluid.
If the level is too low, it might not be registering on the temp gauge until it boils, then it goes off the scale.
The collapsed top hose should mean that the water radiator fluid in the engine is not high enough. ie low fluid, If the radiator was clogged it would burst the top hose, not collapse it.
Check the fluid level in the radiator when its cold, take off the cap (see warning) and look inside. The fluid should be right to the top, with spare in the overflow tank.
Warning!
Dont open the radiator when its hot!!! when the fluid is low, and its hot, it will probably let out steam, and it will burn you.
Now you just have to find the leak, if its been overheating long, it probably has several now. I would start with replacing the hoses and thermostat gasket. Inspect the water pump seal for leaks too, if the level is too low for long it will burn out your water pump too, The water pumping through it, cools it off, if there is no water, its like a garbage disposal, running and running and running.....
good luck.

Are both radiator hoses hot, or just the top one?? If both are hot you are getting good flow, if only the top one is hot and bottom is cold, you have a blockage somewhere. I once ran into a problem on a Chrysler, where we replaced a bad water pump, with a reman, once we were all finished the truck would stll overheat. We found that the shaft on the reman pump broke as soom as we started it up, so it looked like the pump was turning, but the impeller inside wasn't moving. Just a suggestion, I'm sure that is very rare, but since it happened to me, I suppose it could happen to anyone. Keep us posted as to waht you find.Good Luck!!!

You either put the t-stat in backwards, or you have a blown head gasket. Those are the only two ways I'm aware of to collapse an upper hose. Well, using the wrong water pump would do it too, but you didn't say anything about replacing the pump recently.
