DIY Solar Water Heater! – Solar Thermal COPPER COIL Water Heater! – Easy DIY (Full instr.) 170F

DIY Solar Water Heater. A Homemade “flat panel” COPPER COIL Solar Water Heater. Easy DIY. Full Instructions. super hot temps (sustained at 165F+). fast hot water. no electricity needed. easily hooks up to standard water tap/garden hose. reaches temps well over 150F (water pasteurization temp) so it works to clear/kill any pathogens (if a non-municipal source is used). it’s super portable so it’s good for camping/off-grid/emergency as well as everyday use. couple of notes: water flow rate verified with a measuring cup and a stopwatch. (roughly 1 oz. of hot water every 1 to 1.5 seconds and scaled up – one gallon every 2-3 minutes or 20-30 gallons per hour). about the copper tubing: a 50 foot roll of tubing is much cheaper than smaller rolls connected. *only .95 for 50 ft (but for a 20 ft roll and for a 10 ft roll). the glass is just standard window glass and the paint is flat black. it’s thin flat design allows it to be easily stored in a closet, under the bed etc… *”seal it” according to your climate conditions and whether you plan to leave it outside.

  1. This is by far one of the easiest hot water panel builds I have seen. My questions are 1. How big is your storage tank? Must have to be large as the volume isn't that much. I would think that using 1/2" copper tubing would drop the water temp a little, which would be ok, and dramatically increase your volume ability. It also appears, that as hot as the water is coming out, a person could use this panel or a series of panels for a radiant heat system in the home or shop. Your thoughts.

  2. Great Would you try to use a Fresnel Lens but to calibrate it in a way that the sunlight rays focused on the Copper coils only and Let's See how much the water temperature can be increased ?? 10x great video.

  5. watch for copper tubing at estate and garage sales, even with todays prices, I have found tubing, used it to chill my homebrew, but…might be hunting for some to heat water

  6. This is a good idea as a collector, but You need to store the water and keep it hot so the water need to be circulating inside of a water tank. This is just part of the job , but maybe I am am misunderstanding.
