  9. nice video!I had the same ideea about a year ago but still would use a pump for safety reasons considering the 15 meters length of the copper tubing circuit…

  10. If someone made one, in Canada and do a report on it. I thank it will work
    very good for about 5 to 7 months a year maybe ? It can be 20 deg.outside here in north Alabama and the inlet temp = 140 to 145 deg.
    Heat Exchangers do lose about 30 to 50 Per. of the heat. Raphael DIY

  11. Hey thank you for your reply. I’m not worried about freezing as I’ll use glycol and a heat exchanger indoors, but what I worry about is the panel’s ability to heat up faster than it’s losing heat to the -20 celsius exterior… do you think it will provide hot water even at that high outside temp?

  12. Darwin Thug , You can used it, If you Drain any Pipes That will freeze.
    Here in north Alabama I have to drain it at night, when it will freeze outside
    of the house at night it’s ok if Sunshine during the daylight hours. Raphael DIY

  16. My view is that the single, serpentine is likely to perform more
    consistently It gets the water up to usable tank temp.
    My existing solar hot water heater has performed flawlessly for forty years so I
    will go with a proven design. Its simple and easy to make, no hassle to
    maintain.

    parallelled pipes will pass far more water with less pressure drop. In a perfect world, water would flow down each tube equally, thus, without any way to control the flow rates, the reality is that it won’t be even.

  17. You can fine old solar commercial system for sell they go sour make a bad name for solar A Thermosiphon Solar Water Heater will be there for you no problems Just Drain system in cold months But I just drain when needed.
    A heat collector made with copper flow-tubes with solder on copper absorber Fins will provide more hot water at higher temperatures than, any other types of metals.
    The DIY must have a general background in the areas of science, physics, and engineering science. Raphael

  18. You can use black tar or silicone service temp-60f to 400f caulking on flow-tubes before placement of the formed fins on the flow-tubes or just solder them on. Place the formed fins on flow tube with the black tar, or use caulking and insulate one from the other with caulking or tar..use7/8 inch sheet metal screws to hold fins to 4ft. X 8ft. plywood. Making sure it has a good bond between fins and flow-tubes.Than paint it all black use flat-black paint. Raphael
