What is the suitable quantity of vacuumed tube solar collector to warm a swimming pool with the following data

Question

area 12 m * 7 m

location amman, jordan

needed temp. 27 C

Answer 1

Vacuum tube collectors are high-tech systems designed to efficently heat water to 40C and above for process heat or domestic hot water. They normally use a closed-loop heat capture fluid circulation (using specialty liquids) that then needs a heat exchanger to deliver heat to the end use. This adds complication and expense. Swimming pools need only a modest temperature rise in large volumes of water. Quite frequently, if the pool is protected from wind, a black bottom to the pool is all that is needed. If more heat is required, swimming pool solar heaters, which are tube and rib plastic mats, are far more cost effective than vacuum tube collectors.
