i was wondering how much black pvc pipe i would need to effectively raise the temp in my pool, first let me say i live in Maine, so we do have a short swimming season without some type of heater, and 2nd i have a 20x40 in ground pool and 8 ft at the deep end, it holds around 33,000 gallons i believe, thank you. just trying to figure out if i would go broke buying enough pvc pipe to heat it at all, also which size is better to use? i have heard conflicting opinions.

It is all about surface area. The surface area of the water that contacts the tubing and the surface area of the panel exposed to the sun. That is why solar panels are made up of lots of small tubes usually around 1/4". Larger tubing is less efficient at heat transfer to the water.

The size of the panel (sq-ft) will determine the rate at which the pool will heat. Most people go with as large a panel that will fit on their roof or up to 80% of the pool surface but you will gain some heat gain with any size.
