An electrically powered apparatus for generating a solute such as chlorine to sanitise a body of water such as a pool or spa, a by-product of such generation being an explosive gas such as hydrogen, said apparatus including: a) an electrolytic cell ( 1 ) adapted to operate in a substantially vertical orientation through a range of 45 degrees either side of the vertical; b) a water inlet ( 13 ) and outlet ( 14 ) both located at the lower end of said electrolytic cell ( 1 ); and c) a defined space ( 16 ) surrounding one or more electrodes ( 28 ) of said electrolytic cell ( 1 ), wherein, in, the event that water flow through said apparatus ceases and said electrolytic cell ( 1 ) continues to produce said explosive gas, said explosive gas will displace water in said defined space ( 16 ) until there is no water around said electrodes ( 28 ).
