Abstract: A solar heating system implemented inside a concrete slab around a swimming pool, wherein said system absorbs solar thermal energy and heats the water of the swimming pool, wherein said system comprising of a plurality of areas around the swimming pool; a plurality of solar thermal collector being embedded inside said areas; a plurality of height adjustment means to keep said solar thermal collector in a specific height; a separator means to separate said solar thermal collector from the ground and acts as a holder of said solar thermal collectors; an insulation sheet being placed under said separator means; a plurality of trenches being designed between said areas to use as a space to connect said solar thermal collector; concrete being poured into said area to cover said solar thermal collectors; and a pump being used to circulate the water of said swimming pool to a plurality of filters and said solar thermal collectors.
