Magnetizer® “RWE-S” efficacy is calculated in accordance with the size of a house and the hardness present in water. A bigger house with extremely hard water conditions requires the installation of extra units mounted at a distance of 1 inch from each other.

Below is the rule of thumb for the proper selection of the Magnetizer® systems:

If a home is < 2,500 sq. ft. (>230 m2) then 1 unit of RWE-S is required.

This means that there are two rings required for cold water inlet and hot water outlet of heater/boiler.

If a home is around 2,500-5,000 sq. ft. (230-460 m2) then there is the requirement of 1 unit of RWE-S + 1 unit of RWE-1.

It requires a total of three rings in which 2 rings are placed 1 inch apart on cold water inlet and one on the hot water outlet of the heater or boiler.

If a home is > 5,000 sq. ft. (>460 m2) then 2 units of RWE-S are required.

This means a total of four rings: two rings placed 1 inch apart on the cold water inlet and two rings placed 1 inch apart on the hot water outlet.

If your home is located in hard water area which has >10 grains ppm then you require double RWE quantity to attain the effective outcomes.
