Heat wont get hot anymore
Recently I've noticed this winter that my heat really doesn't kick in like it used to. When I first got the car, it worked good, and now this year it's gotten to the point where it blows cool when it's below 29 degrees... I've topped off the coolant with the BMW brand because it was low at first, and days later its still blowing cool... Sometimes it'll warm up but not very often. Any advice? Thanks

you're in Florida! You don't need heat!
How low did the coolant get? You might have an air bubble preventing flow to the heater lines. You might want to find a MINI savvy mechanic and have them bleed the system. GEN1 S is kinda tuff to bleed properly.
You might find a local owner with the expertise by a) identifying your town and/or b) checking http://www.sunshineminis.org/forums/index.php?style=2

You added coolant, but was it ever changed?
the heater core might be plugged.....rust, etc bulids up in a coolant system when the fluid is not changed regularly, and tge lowest point in thw systen, with the narrowest tubes/passages is the heater core....
Might be able to flush it, but many suggest new. Check the engine temp with a scanguage, etc to check for a stuck thermosts first, and mayve bleed it just incase you have an airbubble.

Well the reservoir leaks sometimes, but recently it's been holding, the lowest it got was to where the reservoir was empty, but that was a while ago.

who flushed it?
I'm still guessing it was improperly bled
did they know there are 2 coolant bleed points on the top end of the GEN1 S cooling system?
btw - GEN1 S colant res' - ever been replaced? They only last about 4 years then the seam splits and they leak.
this one is leaking from the back side - the side against the firewall. It was the second one I'd put in this car.

Here is my reservoir.. And I had it done at a shop. Yes I would imagine so, as I could see that the points were opened when I first got the car back from him... I could see where they had been taken off

It is also possible the thermostat is stuck open. Check the upper radiator hose when the car is at operating temp. It should just about be too hot to touch if everything is working properly. If you can comfortably grip it, I would go with that first, before diagnosing it as a heater core.
Let us know what you find.
Also another point - If you ever had green coolant mixed with factory, that can cause the coolant to turn into a jelly and block everything. Even when doing a coolant flush, this can stay behind and cause your heater core to be blocked. Just a thought, but I would check the temp on the hoses first.

Good to hear yours is working again, but just so you realize, your car, according to your signature, a 2008 clubman, is a VERY different car...different motor, etc, so posts in the gen2 section might be more useful for you.
