  2. So what happens at night? how do you maintain temperatures when there’s no
    sunlight? :/

  4. What temperatures were you running before you installed the solar heater?

  5. New video upload giving a quick rundown of a solar water heater I made to
    keep outdoor fish tank water warm during the chilly Arizona winter.

  8. Great idea, Randall! Super simple and seems like it works very well. This
    could have some great overlap in other applications too like off grid
    living. Nice work!

  9. found you on bkudell’s channel. i, too, am in arizona…Lake Havasu
    City…hoping us Arizonians could show our systems (share info) since we
    have to deal with such drastic heat in the summers. Thank you for your

  10. Thank you! Later in the winter I removed the 1/2″ irrigation tubing and
    made a revision using 3/4″ PVC pipes painted black and oriented vertically,
    to make use of the thermosiphon effect. Water flows in one pipe at the top,
    down one side, into a manifold on the bottom, then up through 12 pipes into
    a top manifold, and finally out the opposite side it entered from. Flow
    rate and temperature change both seemed to improve when compared to the
    model shown here.

  11. To many places to leak. Should have used it in roll form with only chance
    of 2 fittings to fail.

  12. Hi man, appreciate your work and sharing! One word though, you REALLY want
    to insulate your pipes, especially (but not only) the hot return one
    -otherwise, there’s too much loses to the environment, first water cools
    down while traveling to the heater, then heats up (but starts from already
    lower temp than if the feed pipe was insulated), than heated water returns
    and cools down again, on its way back. Insulation is crucial. Keep up!

  13. That was my original thought as well, and to be honest, filling it up for
    the first time I had my fingers crossed. Not too long ago there was a
    failure in the system due to a low-flow condition which caused excessive
    temperatures. Oddly enough, not one of the barbed or compression fittings
    for the 1/2″ tubing failed. A blister formed in the tubing itself, which
    eventually popped, and the slip-to-male-NPT PVC adapter partially melted.
    By the time I found it, steam was coming out of the exit.

  14. Rest assured, if this weren’t just a quick experimental setup, I would’ve
    definitely picked up some insulation for the piping, as well as the AP
    system itself. Notice the growbed, fish tank, and sump are all uninsulated
    as well. Stay tuned to see a larger system that’s in the works! Considering
    the flow rate and inlet water temperature, standard PVC should be plenty
    safe, but I will note that CPVC and/or PEX are recommended for hot water
    transfer. Legitimate concern though, good call!

  15. Second thought: have you checked by chance the temps of the piping inside
    the panel? I wonder if it doesn’t get too hot there – so some nasties could
    be released from PVC in there? Appreciate your opinion/experience!
