I believe the answer is:

endothermic

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

'torched mine excitedly taking in heat' is the definition.
I can't tell whether this definition defines the answer.

'torched mine excitedly' is the wordplay.
'excitedly' is an anagram indicator.
'torched'+'mine'='torchedmine'
'torchedmine' is an anagram of 'ENDOTHERMIC'.

Can you help me to learn more?

(Other definitions for endothermic that I've seen before include "warm-blooded" , "(Of a reaction) absorbing heat" .)

I've seen this clue in The Times.
