Loss of coolant

[IVANHOE]

My wifes cooper needs topping up with about 2 pints of coolant a week. The garage can find no leaks, is this normal?
Also, the heater is very poor and seems to work erratically, is this connected to the coolant loss or a separate issue?
The cars has just been serviced at a non BMW garage and runs superbly apart from this problem.
