Anytime Dave! I work with many people in a small solar/wind community here on YouTube. Check out my solar videos and my friend's solar videos. I'm building a solar water heater right now from some plans that were used the produced some amazing results. The biggest problem people face with solar water heating is that there's too much hot water and it's too hot. Water heaters bypass to the sewer at 150F by law, my friends septic tank was destroy because of solar hot water :)

DIY Solar Water Heater Innovation Volume 3by debeshbhattarai1,353 views
UPDATE : Ive been thru a northern florida Winter now..and heres the performance i got out of the Collector :
50 f. max. daytime temp. with full sun gave me 125 f. water temp.
55 f. max. daytime temp. with partial sun gave me 110 f. water temp.
55 f. max. daytime temp. with full clouds gave me 80 f. water temp.
Im delighted with the results . We had an 18 f. night and no damage resulted to the Tubing that was full of water .

I guess you could if you wanted to harvest every bit of sun, but, as it is Im getting typically 150-160 f. with it stationary and its now Fall in northern Florida .

Thank you for your kind comments. I installed the Collector in August and now its mid-October, im still getting the same performance results ... and its 20 f. cooler outside. This surprises me and im quite happy about it.

Notes : 1. UV rays are not a concern because the chosen glass eliminates almost all of the UV, plus the Pex is painted black 3 times over. 2. Expansion of the Pex coil is not a concern because space is left around the Pex Coil within the Box. 3. Performance is exceptional... a 40 f. temp. rise within the Box after 2 early morning hours of direct sunlight . 4. Copper was considered, but it is cost prohibitive for a low cost install . 5. Doesnt need draining down...no hard freezes .
