Overheated house at central Tooting (3)
I believe the answer is:
hot
'overheated' is the definition.
('hot' can be similar in meaning to 'overheated')
'house at central tooting' is the wordplay.
'house' becomes 'ho' (abbreviation for house).
'at' is a charade indicator (letters next to each other).
'central' means to look at the middle letters.
The centre of 'tooting' is 't'.
'ho'+'t'='HOT'
(Other definitions for hot that I've seen before include "(Of food) spicy" , "Stolen - sought after" , "Fiery" , "Having a high temperature" , "Under the collar, it means anger" .)
