Step by Step Guide to Build a Solar Pool Heater
There are many variations in building a solar pool heater. We'll take the easiest variation in which the solar pool heater is built.
1) The area of the solar panels should be at least 50% of the surface area of the pool. In other words, if the surface area of the pool is 100 square meters (1,036 sq ft), the solar panel assembly should be at least 50 square meters (538 sq ft). If the surface area is less than that, the heat loss will be faster and the temperature of the water in the pool will be lower than your requirement.
2) Take a plywood plank of the required size, paint it black, and let it dry.
3) Once the plank is dry, take the hose and wound it into a coil. Use clamps to fix it on the base. This can be a little tricky and can take some time, but make sure you clamp the hose properly after every coil. This will prevent the hose from moving out of its place.
4) Place the assembly near the pool if there is enough space, or place in on top of a nearby structure. Position it at a slant angle such that it faces the southwest or the northwest direction so that it gets exposed to the sun for a longer time.
5) Connect the outlet of the chlorinator to the solar pool heater assembly and then let the outlet of the solar pool heater assembly be directed into the pool. Make sure water from the solar pool heater does not run along the walls of the swimming pool thereby losing heat.
Now we have our own solar pool heater and no second thoughts about running up the electricity bill.
