My heater isn't so great. The heater in my old FC (and most FC's I've been around) was fantastic, it would run you out of the car easily and it was up and heating very quickly.
I've seen someone who disconnected the heater hoses and rigged up a bilge pump to backflush cleaner through the heater core to remove all the crap in the core to get it working better again. My concern would be the caustic cleaner could burn a hole in the heater core causing a pinhole leak, meaning new heater core and GIANT pain in the *** to fix.
But, I have been seriously considering doing that on my car as an experiment to see how much junk was in it.
It's a shame than FD heaters aren't that great. Hell, the engine puts out an INSANE amount of heat, there's no reason that heat can't be used to warm the passenger compartment!

Mines parked until the white stuff is gone but in the fall here it gets pretty cold so i'll contribute.
My heater is Godly. It can produce stupid insane amounts of heat if i want it to or none at all. Insane to the point where your feet start tingling and you're forced to turn it down.
There is, however, a flaw. Apparently a common flaw. My climate controls work.. intermitently. It was stuck on full heat and fan on 4 for a good little while. I'm sure the engine didn't mind.. Then it started working so i put heat about half way and fan on 2 where I think it got stuck again right before I parked it.
As for the gunk question? I'm definitely not the most knowledgable but to me the answer is very obvious.
-If you don't have gunk and your heater works great: there is clearly nothing wrong.
-If you don't have gunk and the heater isn't doing it's job, look around. Thermostat? Flush heater core? etc.. Shouldn't be too hard of a fix.
-If you DO have gunk and it's working: consider a flush soon as gunk could clog heater core
-If you DO have gunk and the heater isn't working: gunk may be clogging heater core. Flush it. If still not working, probably a problem already mentionned BUT, you will have flushed your coolant.
Also, I don't think it's fair to say gunk=coolant o-ring failure. Obviously this isn't the only thing that causes the gunk so why go there right away.
Are our cars the only cars with this gunk though? I never hear about it anywhere else.
