Electric appliances or the gas alternative put before consumers (7,7)

'electric appliances' is the definition.
I don't know anything about this answer so I cannot judge whether it can be defined by this definition.

'or the gas alternative put before consumers' is the wordplay.
'alternative' indicates an anagram (an alternative ordering of the letters).
'put before' is a charade indicator (letters next to each other).
'consumers' becomes 'eaters' (eater is a kind of consumer).
'or'+'the'+'gas'='orthegas'
'orthegas' with letters rearranged gives 'storageh'.
'storageh'+'eaters'='STORAGE HEATERS'
