Pool heating device system

An attachment apparatus for heating liquid, the attachment apparatus comprising:

• (a) a body having a fluid passageway from a first opening to a second opening;
• (b) a third opening provided on the body between the first and second opening to allow liquid to exit the body;
• and
• (c) an adjustable diverging mechanism mounted to the attachment operable to split liquid flowing through the body and redirect at least some of the flow out of the third opening;
• wherein the first opening is shaped and sized to mount to an inlet of a pool of liquid and the third opening is adapted to connect to a tube having a thermally conductive outer surface, the tube extending out of the pool of liquid to be exposed to environmental conditions to absorb thermal energy and heating the liquid prior to returning the liquid to the pool of liquid.

A method of heating a pool of liquid, the method comprising the steps of:

• (a) connecting a first opening of an attachment apparatus to an inlet of the pool of liquid for receiving liquid, the attachment apparatus having a body defining a fluid passageway from the first opening to a second opening, and a third opening disposed between the first and second opening, and an adjustable diverging mechanism mounted to the attachment operable to redirect flow out of the third opening;
• (b) connecting a tube defining a fluid passageway to the third opening, the tube having a thermally conductive outer surface and extending out of the body of liquid to be exposed to environmental conditions to absorb thermal energy and be heated;
• (c) adjusting the diverging mechanism to divert liquid flow through the third opening and the tube to absorb heat from the heated tube;
• and
• (d) redirecting the heated liquid back into the pool of liquid.
