If you want an accurate assessment of monthly pool water temperatures, try our solar pool heating simulator/calculator. Just plug in the advice on system sizing you get from this calculator into the simulator to see if you're going to be happy with the season extension.

Note: use Google maps to approximate your collector compass facing direction; true North points up on the page.

* Use a time and area average, hence if half the pool is shaded for half the day, the setting should be 25%. As another example if 100% of the pool is shaded for half the day use a 50% setting.
§ Please note, while a solar blanket will make a large difference to the water temperature, we don't recommend you size down your system as you may get tired of using a blanket, or you may sell your house. However, if you do want to size it down you can use the previous Usage, budget and expectations settings.
‡ Please refer to our solar pool heating manuals on our download page for different types of plumbing arrangement. Note: manual systems are sized with 20% larger collectors to account for the fact that most people only use manual type systems over the weekend.
