Abstract
Hot water pipes, in areas with hard water, tend to fill with scale until they no longer pass enough water. De-scaling water pipes with acid is dangerous, expensive and damages the pipes. Ion exchange and reverse osmosis water softeners eliminate scale buildup in pipes, but are expensive. This invention is a means of keeping the scale precipitate, created when water is heated, inside the water heater by passing the hot water through a removal medium where the scale sticks to the surface. The removal medium can be placed inside the water heater or in a separate tank connected to the water heater; both configurations remove the precipitate from hot water; both save hot water pipes from scale accumulation.
Claims12
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.
A method for creating a supply of hot water for a building, which reduces scale in the hot water available to adhere to hot water pipes, the method comprising:
- heating a quantity of water in a hot water heater to a temperature that reduces the solubility of a precipitate associated with the scale, the quantity of the hot water being sized to supply the hot water to the building via the hot water pipes;
- and
- directing a flow of the hot water from the hot water heater to a housing, the housing being adapted to pass the flow through a removal medium in the housing to adhere an amount of the precipitate upon contact to the removal medium, wherein the removal medium loose media and a surface area larger than a surface area of the housing and the removal medium comprises a number of passages to allow the hot water sufficient time to pass through the removal medium to adhere the amount of the precipitate.
