'non-heated' originates from the prefix 'non-' meaning 'not' and the word 'heated' from the verb 'heat', which comes from Old English 'hǣtan', meaning 'to make hot'.

'non-heated' evolved from the combination of 'non-' and 'heated', where 'heated' is derived from the Old English 'hǣtan'.

Initially, 'heated' meant 'to make hot', and 'non-heated' has retained the meaning of 'not made hot'.
