Kaput goes vast heater! (3,5)

Ross

I believe the answer is:

gas stove

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

'heater' is the definition.
I don't know anything about this answer so I can't judge whether this works.

'kaput goes vast' is the wordplay.
'kaput' indicates an anagram.
'goes'+'vast'='goesvast'
'goesvast' with letters rearranged gives 'GAS-STOVE'.

Can you help me to learn more?

(Another definition for gas stove that I've seen is " Type of cooker".)
