Abstract

Scale preventing device (1,2,3,4,5) is a new product made of metal or plastics which is mounted onto the cool water supply pipe (6) by means of a ball valve (4) with buterfly and a ball valve (5) with buterfly onto a cool water drain pipe (7) toward a protective valve of a boiler (9) of a tank (10) of the boiler, and is used every six months depending on the water hardness, and that by means of ''Calgib'' powder or some other agent for elimination and prevention of water scaling on en electric heating element and inside the walls of the tank (10) of the boiler, is poured into. Closing the ball valve (4) with butterfly and a ball valve (5) with buterfly, protective covers (8) are removed and a ball valve (3) with buterfly is opened and the water is drained from a cylinder (1) and then the ball valve (3) with buterfly is closed and thereupon its protective cover (8) is put back. A ball valve (2) with buterfly is opened and by means of a funnel through it, the space of a cylinder (1) is filled with ''Calgon'' powder, and then it is closed is the ball valve (2) with buterfly and its protective cover (8) is put back. The ball valve (4) with buterfly and the ball valve (5) with buterfly are opened, thus the water from the cold water pipe (6) inserts from the cylinder (1) the powder, through the cold water drain pipe (7) toward the protective valve (9) into the tank (10) of the boiler, and switch on the heating element of the boiler (10).
