How do solar pool heaters operate?
They run on a passive solar principle.
Simply, pool water runs via long lengths of flexible tubing. These are suspended in front of reflectors to receive and transmit the sun’s warmth to the water in the tubing. The tubing really should be protected, say with with polythene sheeting, from any wind chill.
The reflectors might be produced out of halved storm water piping, sprayed with chrome paint to maximise their reflective powers. To circulate this warmed water via your pool or spa you will need a small pond pump or solar electric pump. The latter is far more expensive, but clearly you will support the surroundings as well as your wallet by spending slightly more to begin with.
Minimum pump specifications really should be that it delivers ten litres per minute (120 gals/hour) and is capable of raising water to 1.6m (52).
All components, containing tubing, reflectors and cover, are assembled into a solar panel. Its best size is determined by optimum dimensions for ease of handling, structural integrity and heating efficiency. Not surprisingly more than a single panel might be employed. A spa wouldn’t need a sizable panel. But then again… some like it hot!
In general, a panel measuring 3.4m (11 4) by 1.4m (4 
is effective on pools as much as 30,000 litres (6000 gal).
Panels really should be placed in such a solution to maximize receipt with the sun’s rays. It’s best to have them face the sun’s mid day position. Place them vertically on a fence or horizontally on your roof.
To create the very best of one’s diy solar water heater, it tends to make sense to make use of it having a solar blanket. But this is not typically necessary to benefit from your now upgraded asset – your pool or spa.
