An example boiler apparatus (501) for continuously processing water containing dissolved matter is disclosed. The boiler apparatus (501) including: a boiler vessel (515) with an inlet (523), a first outlet (517) and a second outlet (529). A third outlet (511) may also be provided. The boiler vessel (515) includes a heating element (522) located within the boiler vessel (515) arranged to provide a wet steam product at the first outlet (517) and/or third outlet (511) and create convection within the boiler vessel (515) such that a concentrated product is provided at the second outlet (529) which is relatively lower than the first outlet (517). A system including a boiler apparatus and related methods are also disclosed.
