I believe the answer is:

heine

I'm a little stuck... Click here to teach me more about this clue!

'heinrich the' is the definition.
I can't tell whether this defines the answer.

'hot-headed one' is the wordplay.
'hot' becomes 'h' (abbreviation eg on taps).
'headed one' becomes 'eine' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'h'+'eine'='HEINE'

Can you help me to learn more?

(Other definitions for heine that I've seen before include "Heinrich -, nineteenth century German poet" , "Heinrich -, Ger. poet" .)

I've seen this clue in the Evening Standard.
