For more eco ideas follow us on: www.facebook.com This self-built solar water heater is made of plastic bottles, black painted milk cartons and PVC pipes. It is popular in southern Brazil. The water is heated passively by solar energy. As the hot water rises, it is naturally replaced by cold water, so no pump is needed. Construction reference: www.youtube.com
heated plastics release dangerous xenoestrogens, which alter your DNA; the make men like women and women like super-bitches. might wanna check that out?

@charizgr Did you notice that the water never touches the plastic bottles?

id like to see some plans of how it actually works and is plumed and put together, also i would think it would be more efficient if the bottle arrays were housed in a box with a glass or poly top or sides too

@mygabrielhernandez 1st of all you cant escape BPA its everywhere but who says the water would need to be drank or to come in contact with you at alll? it wouldnt it could be used to run a forced hot water heating system or as a closed loop to heat water for the tap or the shower, i resovoir tank heavily insulates with 2 coils,1 to the solar heater and 1 to the water line ,like a heat exchanger

BISPHENOL A could be in the heated water. This substace raised concerns on human health, from fetuses to grown human beings. Please, do a water chemical analysis.

Recomendo urgentemente fazer análise química da água armazenada. As garrafas plásticas quando aquecidas liberam Bisfenol A que é substância usada para fabricá-las. O bisfenol traz gravíssimos riscos a saúde humana (cérebro, tireóide, sistema nervoso, próstata, câncer de mama, etc). Uma pesquisa rápida na Wikipéia pode esclarecer um pouco mais. Mesmo usando a tecnologia PET ainda há risco para a saúde.

tried this, except I painted the backs of the bottles with flat black, went in for lunch, came back out to a wrinkled mess, next one will be black painted copper through pop bottles lined with reflective Mylar, gonna try a slight vacuum in the bottles as well

…for your information, heat could polymerize the plastic and releases toxins in the water!
Not sure how serious can be, but certainly reaches our system also through the skin!
Maybe some doctor knows more about?

@davidsj5566 One approach to avoid freezing is to have not water circulating inside the solar collector but some kind of antifreeze and let the antifreeze heat the water using heat exchanger.

That’s AMAZING! I didn’t quite catch how to do it, but it sure looks cheaper than a solar panel!

@davidsj5566 In Brazil we don’t have water freezing temperatures. Maybe enough to freeze water poodles or droplets of water, but not water inside tanks or pipes.

hi there very nice job, what would you do to provent the pips from freezing in winter time just asking. i like you idea and would love to put it to work in my home but i live in ireland, and it gets a bit cold in winter.
nice job

Well as you can see without metal it wont go above 45c even on a hot day. Which is fine and jolly good given that they used what was available and its a warm climate. But in the uk blackened stainless steel with one side weighing 9 kilos and one kilo of water traveling through the panel and then being stored in an insulated tank and fed back round is best. and will work even on a cold day the tank contains enough water for the house hold. The maths is basic physics.
