Claim:
A system for heating water from a swimming pool of the type having a pool of water and a pump pumping a flow of water through an inlet into the pool of water, the system for heating water comprising: (a) an attachment apparatus having a main body defining a fluid passageway from a first opening to a second opening and a third opening, the attachment apparatus further having a connecting portion with the first opening defined therethrough, the connecting portion connecting to the inlet for receiving a flow of water through the first opening; (b) an adjustable diverging mechanism mounted to the attachment apparatus, the adjustable diverging mechanism operable to selectively direct a portion of the flow from the first opening to the third opening, the diverging mechanism includes an adjustable flow restrictor cap mounted over the second opening having a stationary plate provided between the second opening and the restrictor cap; and (c) a tube having a flow channel and a thermally conductive outer surface, the tube coupled to the third opening and extending out of the pool of water and exposed to environmental conditions to absorb thermal energy and be heated; wherein the portion of the flow of water directed to the third opening is heated when passing through the flow channel of the tube and then returned to the pool of water; and wherein the flow through the flow channel is provided only by the pump of the swimming pool.
