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.
Claims23
An apparatus to reduce scale in hot water, the apparatus comprising:
- a hot water heater comprising a tank having a water intake and a hot water outlet, and a heater coupled with the tank;
- and
- a housing coupled with the tank via the hot water outlet at a housing intake, wherein the housing comprises a removal medium, media of the removal medium being loosely positioned to pass water between the hot water outlet and a housing water outlet, the housing water outlet being adapted to couple with a hot water pipe and comprising a surface area about the removal medium that is smaller than the surface area of the removal medium.
An apparatus to reduce scale in hot water, the apparatus comprising:
- a commercial size water heater to heat water to a temperature that reduces the solubility of a precipitate associated with the scale;
- and
- a housing coupled with the commercial size water heater to receive a flow of the hot water and 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 comprises a number of passages to provide a commercial hot water supply to a building and a surface area that is larger than a surface area of the housing within which the removal medium resides.
An apparatus for creating a supply of hot water, which reduces scale in the hot water available to adhere to hot water pipes, the apparatus comprising:
- a water heater to heat a quantity of water to a temperature that reduces the solubility of a precipitate associated with the scale;
- and
- a housing to pass a flow of the hot water from the hot water heater through loose media of a removal medium in the housing to adhere an amount of the precipitate upon contact to the removal medium, wherein the removal medium has 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 to pass through the loose media.
A central hot water system to reduce scale in hot water to supply a building, the system comprising:
- hot water pipes to supply the building with the hot water;
- a water heater to supply the hot water at a temperature that reduces the solubility of a precipitate associated with the scale;
- and
- a housing coupled with the water heater to receive a flow of the hot water and 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 comprises a number of passages to pass the flow through loose media of the removal medium, a surface area of the removal medium being larger than a surface area of the housing.
