DIY Network Solar Poly Tubing

Cut to size a piece of 3/4-inch plywood to an approximate measurement of 4 feet by 4 feet.

Create a border around the edge of the plywood board. Do this by using screws to secure four additional cut-to-size pieces of plywood to the board.

Cut a circular inlet hole with a jigsaw in one corner of the plywood backboard. This hole should be big enough to allow an elbow fitting to fit snugly through the aperture.

Mark out screw holes against the board, diagonally from corner to corner in a crosslike pattern. Keep in mind you can share one screw for two overlapping brackets and mark the holes accordingly.

Unfurl the poly tubing and feed into the corner inlet hole via the corner elbow fitting. Proceed to create a concentric circular pattern, ensuring that enough tubing is coiled and evenly spaced in between the appropriate holding bracket holes. As you approach the center, be aware that the circling will become tighter and the tubing more prone to kinking. Stop before distortion of the tubing occurs and mark out a hole for the outlet elbow joint.

Cut out the centrally placed hole with the jigsaw for the outlet elbow joint.

Place the brackets onto the board and screw them carefully down until the tubing is secured

Coat the completed board and all attachments with matte black paint using the spray can. It's best to complete this task in a well-ventilated location, preferably outdoors. Hold the can about a foot away from the board and proceed to spray in a wide, sweeping action until you've achieved comprehensive paint coverage of the board.

Connect a T--ball valve with an additional pressure gauge to a pump-driven filtration system and attach the required length of poly tubing. This allows you to open the valve on a sunny day, thus letting the pool water circulate and heat through the poly tubing in a controlled manner.

Run the tubing to your DIY solar heating board and securely fix it to the corner elbow through the back of the plywood board.

Complete the circuit by securely attaching an additional length of poly tube to the center connecting elbow joint through the back of the board. Place the end of the pipe into the pool.
