Tell us about yourself!
I guess you can say the same about every instructable in this site. Go out and buy something. The whole point of this site is to make it yourself, or at least that's what I thought. :)
OMG - 500 METERS!!!! That is 1 massive project. Good for him. Way too ambitious for my little pool. :)
I agree, the flow rate would not make that much difference in the overall efficiency of the system. Slow lets the water pick up more heat but delivers less water overall, faster picks up less but delivers more water over the same period of time.
LOL, no issues, will always try my thing. People can see and make comments, good or otherwise. There's always more to learn and build. :)
I've posted the temp rise a few times, 1.5 to 2.5 degrees. Flow rate where? The flow rate in the 2" pipe is much faster then the flow rate in the 1/2 in polypipe. It's also completely adjustable. The solar unit is tied into the centre or the three splash pad returns. Look at the picture of the pool and you will see the splash pad. I can have the flow gentle or blasting 18" up above the pad. The more flow I direct into the splash pad the higher the flow rate to the pad and the lower the flow into the 2 pool returns. I tend to keep it on the gentle side, unless the Grand kids are visiting, they like it blasting!!! :)
That's awesome. I was thinking the exact same thing after I built this. There's a nice UV resistant dark tinted sheet that would work very well. What did you do to create the fittings for the end of the coroplast? I would love to see the design you came up with. I have some designs going back a few years for exactly this sort of thing, just never had the time or inclination to create a prototype.
Yes, I agree with your statement. I designed mine to be slow flow and low pressure so as not to put much strain in the connects. The minuscule difference in efficiency I was willing to give up for the added security of not needing to worry about a blown connection. :)
Check some of my replies above regarding the design. About the temp build up, the system is always partially open so any pressure build up through temp rise would distribute through the system. Good point though, for anyone looking to do this. Though water does not expand much when warmed up, unless it gets hot enough to vaporize, then anything would blow to bits at over 200 degrees, and probably melt. It's the air that can get into the system from time to time that can heat up and expand. Air sucked into the vacuum or pool level drops below the skimmer due to too much splashing or evaporation. :)
