Why is there a weird smell when heat is running?

What is your question?

When i turn on and run my heat in my 2012 Mini Cooper Countryman S, it first takes a long time to heat up and once it is hot it produces a strange smell. Has anyone had a similar issue to this or know what could be causing this issue?

What makes this problem better or worse?

worse the longer the heat is on
