Abstract:
1. A method to reduce scale in hot water, the method comprising: directing a flow of the hot water into a housing, the hot water having a temperature that reduces the solubility of a precipitate associated with the scale; passing the flow between loose media of removal medium in the housing to adhere an amount of the precipitate upon contact to the loose media of the removal medium, wherein the removal medium has a surface area larger than a surface area of the housing and the loose of the removal medium are capable of movement in response to the flow when adherence of the precipitate to the loose media of the removal medium restricts the flow; and switching, via a valve, the flow between the housing and another housing containing said removal medium to designate an in-use housing and an offline housing, wherein the in-use housing receives the flow and the flow is blocked from reaching the offline housing.
