Stove, cooker (4)
I believe the answer is:
oven
I believe this clue is a double definition.
'stove' is the first definition.
(I've seen this before)
'cooker' is the second definition.

(Other definitions for oven that I've seen before include "Compartment for heating" , "Kitchen appliance" , "A hot place" , "Metal box in which to roast" , "Compartment for baking" .)
