Abstract:
The invention relates to a domestic water heating system, which comprises: (A) a main water tank; and (B) an accelerator having a sleeve, which in turn comprises a mechanism for flushing lime scale accumulated at the bottom of the internal hollow of the sleeve, said mechanism causes a flow of cold-water from a cold-water inlet, to said bottom of the internal hollow of the sleeve, and from there to the main tank via hollows in the sleeve.

Claim (Index 5):
The domestic water heating system according to  claim 1 , wherein said flushing mechanism comprises:\n a. a perforated tube which is attached to the bottom of the main water tank, said perforated tube having a top opening, and plurality of holes at a lower portion of its outer wall; b. a cup having a top opening; and c. a sinker having a cylinder which passes through the cold-water tube, through the top opening of the perforated tube, and through the top opening of the cup, said sinker having a bottom valve and a top stopper along said cylinder; wherein, in a stationary state when there is no cold-water flow within the cold-water tube, the bottom valve is located within the cold-water tube, while upon consumption of hot water, a pressure due to a cold-water flow in the cold-water tube elevates the sinker, thereby to raise said cup due to contact with said top stopper, thereby also to open a passage from the interior of the cup into the main water tank, and to cause a flow of limescale-flushing cold-water from the cold-water tube and through the perforated tube holes to within the main water tank.
