  4. Cover with corrugated plastic roofing
  5. Connect to your pool’s pump system
  6. Angle toward the sun (typically at your latitude angle )

This more advanced system can raise pool temperatures by 5 10 ° f on sunny days. For best results, the solar collector surface area should be roughly 50 75 % of your pool’s surface area.

Liquid solar pool cover: the invisible solution

If you prefer not to deal with physical covers, liquid solar covers offer an interesting alternative.

How liquid solar cover work

These products form a microscopic layer on the water’s surface that help prevent heat loss through evaporation. The layer is invisible and break isolated when disturb by swimmers, so reforms when the water is stillness.

Application process

  1. Calculate your pool volume to determine the correct dosage
  2. Apply the recommend amount monthly or as direct
  3. Pour the liquid near the center of the pool
  4. Allow normal water circulation to distribute the product

While not angstrom effective as physical solar covers, liquid solutions can maintain water temperature by reduce evaporative heat loss by 40 50 % and are passing convenient.

DIY pool enclosure or greenhouse

For those in cooler climates, create a simple greenhouse like enclosure around your above ground pool can dramatically extend your swimming season.

Basic structure design


Materials need:

  • PVC pipes or metal conduit for frame
  • Connectors and fittings
  • Clear greenhouse plastic sheet
  • Zip ties or clamps
  • Ground anchors


Construction approach:

  1. Create a dome or rectangular frame around your pool use PVC or conduit
  2. Secure the frame to the ground with anchors
  3. Cover with greenhouse plastic sheet
  4. Include a door or removable section for access
  5. Consider add simple vents to prevent overheat

This enclosure trap solar heat and blocks wind, create a greenhouse effect that can importantly warm both the water and the surround air. During hot weather, sections can be removed for ventilation.

Wood fired pool heater

For the really adventurous diver, a wood fire water heater can be an effective solution, particularly if you have access to free or low cost firewood.

Basic design concept

This system involve create a heat exchanger where pool water pass through copper or stainless steel coils that are heat by a wood fire.


Materials need:

  • 55 gallon metal drum or similar container
  • Copper or stainless steel tubing (at least 50 feet )
  • Fire bricks or similar heat-resistant material
