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 $ for 50 ft (but $17 for a 20 ft roll and $10 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. UPDATE: (06/01/2018)… if interested, here’s a youtube video link to my other (most current) copper coil water heater. It’s of a similar design but is lined with aluminum sheeting and uses larger diameter coil.
