Bizarre form of basic heating (7)
I believe the answer is:
brazier
'basic heating' is the definition.
Although both the answer and definition are singular nouns, I cannot understand how they can define each other.
'bizarre form' is the wordplay.
'form' indicates anagramming the letters (another form of the letters).
'bizarre' anagrammed gives 'BRAZIER'.
'of' is the link.
Can you help me to learn more?
(Other definitions for brazier that I've seen before include "Metal-worker" , "Outdoor coal or charcoal heater" , "Coal-fire pan" , "heat-source" , "Container of burning coals" .)
