OK, we need to clear a few things up. Generally the "fan" that gets stuck on is the power steering pump fan and not the cooling. In fact, I don't know of a cooling fan that has ever stuck on (could be wrong) but generally when they fail, they are off.
Secondly, the MINI has a closed cooling system which means that you shouldn't be losing any water (a little over a long perid of time) out of the system. If you have to add coolant day to day then you have a serious leak. Generally three places tend to leak... The radiator, the coolant bottle will crack and leak or the thermostat housing. Radiators are rare to be honest, and it is usually one of the other two. If there is a leak then there is likely a bubble in the system which can prevent coolant from moving throughout the system thus no heat in the cabin. This can also lead to the car overheating and cracking the head.
1. Get the leak plugged and the fan fixed of you will be in for expensive repairs.
2. After that you can troublshoot the heating system easier.
