New form of heat pump not widely established (3,2,3,3)
I believe the answer is:
put on the map
'widely established' is the definition.
I know nothing about this answer so I can't judge whether it can be defined by this definition.
'new form of heat pump not' is the wordplay.
'new form of' indicates an anagram.
'heat'+'pump'+'not'='heatpumpnot'
'heatpumpnot' is an anagram of 'PUT ON THE MAP'.
Can you help me to learn more?
I've seen this clue in The Times.
Want a hint initially instead of a full solution?
