A stand-alone non-pressurised hot and cold water dispenser including a dispenser body (11) having a water reservoir (14) able to be replenished by an inverted water bottle (13) removably mountable on top of the dispenser body (11); a cold water tank (15), a hot water tank (16), a non-return valve (28) located in a pipe (17) feeding water from the water reservoir (14) to the hot water tank (16) to prevent return of the heated water in the hot water tank (16) to the water reservoir (14) or the cold water tank (15); and an expansion chamber (21) connected to the hot water tank (16) to allow expansion of the heated water and retain water in the hot water tank (16) substantially at atmospheric pressure. |
