Solar Water Heater from Brazil "Soda bottle solar water heater" -Panasonic ecoideasnet

For more eco ideas follow us on: http://www.facebook.com/ecoideasnet

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.

@nishhalwa Amo os Kenianos. Ja trabalhei com muitos deles la nos USA. Mas sobre o aquecedor com garrafas pets eh elementar. Any one can make. They can send to you a picture how to make it. Only pets,pvc and a water tank .kisses

@MyGabrielHernandez Meu nome eh Arlete, Pelo que eu entendi, as garrafas pets so servem para aquecer o cano que passa por dentro delas. Quero saber se este tal de Bisfenol pode atravessar o cano de pvc que passa a agua entao assim contaminando-a. As garrafas nao sao lacradas, somente uma encaixadas dentro da outra. Poderia este Bisfenol evaporar e nao contaminar a agua q passa dentro do pvc? Sempre achei q o pvc e seguro e nao filtra substancias q estao do lado de fora.Desculpa. minha ign

@MyGabrielHernandez agreed. I think this could have potential affects on water, be interesting to know the result OP :)

@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
