Water heaters in British tankers, for example (7)

Ross

I believe the answer is:

boilers

'water heaters' is the definition.
(I've seen this in another clue)

'british tankers for example' is the wordplay.
'british' becomes 'b' (abbreviation e.g. in BBC).
'tankers for example' becomes 'oilers' (oil tankers).
'b'+'oilers'='BOILERS'

'in' acts as a link.

(Another definition for boilers that I've seen is " old birds".)

I've seen this clue in The Times.
