DIY "PEX COIL" Solar Water Heater! - High temps! - No crimping! - Sun Safe! - PEX Made Easy!

Our Homeless Veterans will want to take a warm shower. This is such an easy solution for providing warm water. Our Veterans will be able to make their own water heaters at low expense. Many times the best ideas are the simplest. The RBVS sawmill will produce the needed wood.

Our mantra: "Triggering tipping-point decisions with simple rules and feed back loops."  Simple ideas allow our Veterans to make decisions that will make their lives better every day in every way! We always looking for game changers!

DIY Solar Thermal PEX COIL Water Heater! Easy DIY! No Soldering, Clamps, Crimp Rings, Glues, Unions, or that expensive crimping tool! In my design it's just 2 push-to-fit "shark-bite" connectors! Because it's all one piece of tube, the unit has no potential internal leak points. PEX is sturdy, tough and rigid. water temp rating range... 33F to 185F-200F (93°C) water! ...and if temps hit or fall below 32F (0°C) it's freeze damage resistant! It'll freeze but doesn't break. The connectors are made to last at least 25 years and pipe is rated for 50+ years! Note that PEX, if left "uncoated" can be damaged by the UV rays of the sun but painting and/or priming with a coating blocks the UV rays (making it sun-safe) and a great choice for DIY solar applications! A detailed list of the parts I used is shown is near the end of the video. PEX tubing will last at least 10 times longer than irrigation pipe and handles higher temps. The cost difference is only minimal: 100' of poly pipe $10.00. 100' of PEX $28.00 Lastly, with research, you'll notice that 'all' non-metal pipe manufacturers will say that they recommend metal pipe over non-metal for solar units but, in my opinion, that's just because they want to cover themselves - say for example if it was used in a large "highly insulated" commercial installation (with mirrors, metal backing, reflectors etc.). in a build like that the collector might reach over the 200F pipe rating (to 220F or something) which could shorten the pipes lifespan to 30 years instead of 50. For a moderately sized DIY application it should work great (even my copper pipe solar water heaters top out at 175F in the hot summer, 110F - 43.33C  in the sun. PEX  is second only to copper for toughness, strength, durability and by using shark bite connectors it makes it super easy to make.
