You either have low coolant, a failing head gasket, or the heater pipes are connected the wrong way around if the matrix is cold.
The E30 heater is an air blending type, so there's a small possibility that the linkage to the flap in the heater box has come adrift somehow.

Not quite that simple, I'm afraid. Next thing to find out is where the coolant went, and whether what you've added is following it!

Electric valve is much more likely.

You'd struggle to find one in your local Tesco's, and I don't think the likes of GSF or ECP do them either.
BMW will have plenty, and there's no shortage of second hand ones around.
First thing to do is take the covers off and see exactly what the problem is. Could just be the O ring seal between the valve and the matrix.
