Calorifiers and Water Storage Heaters – what’s the difference?
None. ‘Calorifier’ is a word borrowed from industrial process heating, meaning a water vessel containing
a heat exchanger (such as a coiled pipe) through which steam or hot water passes, giving up its heat to
the water contained in the vessel.
