Solar Water Heater with Plastic Bottles
How to make a water heater with big plastic (PET) bottles. Inside each bottle there is a 3.5 meteres piece of 4 mm drip watering tubing. This heater takes advantage of the greenhouse effect inside the bottles. It is like the heat inside a car in the sun in summer. Since when the circuit is stopped the water heats more inside the tubing it woul be a good idea to use a timer with i. e. 1 minute ON and 1 minute OFF. This also would protect the pump motor from excessive heating. With a small water pump the water is cycled and the temperature rises. It would be better to use a 12 volt DC motor water pump connected to several solar cells. You can also try to paste a sheet of aluminum foil in order to concentrate more heat inside the bottles. The solar water heater is scalable, so you can connect more bottles and groups of bottles in order to heat a swimming pool.

I liked ur solar water using plastic bottles video but didn't understand what is the device connected between wire tube and water which is in black colour so please respond to my question

Loved the video! I make videos also if you want to check them out, if not its cool but it would mean a lot :) Keep up the good work and i'm happy I found you before you get big on youtube :)

good job
-
very nice.

Neat, but they should be run in series not split with tees, would be far more efficient I think as atm there nothing to control how much goes to either side of each tee and the two buckets are most definitely generating different back pressure forces with the way they're just shoved into the bottles with no regard for folds or distortions in the line. The basic idea is cool still, only needs a few refinements.

tho wottor gots hotter

Great explanation! Any chance that you could have one of my songs in a video?I'd love to have one of my songs in one of your vids! If you'd be open to that?

can i know what things that i need to make this solar water heater,,?? please,,
-
this is stupid and here is why:
he is using electricity anyway for the pump, roughly 35 watts, so why not just heat the water since 35 watts can add 80 degrees farenheit to the temp of 10 gallons water in a 24 hour period given this formula
Watts = 3.1 x Gallons x ΔT (in °F) / Heat-Up Time (in hrs) -
this viodo is very best

Paint them black. Looks good and great concept.
-
Ingenious is that.clever STUFF.
-
never ever drink or wash your body from a heated plastic bottle... you have no idea what toxins come from that plastic
-
Feels like just leaving a large bottle of water out in the sun is cheaper, easier and just as fast.
-
Rather than tin foil I'd paint the bottles matte black and store to water vessel in foam or wall insulation. You are losing so much energy with this, but it is a good proof of concept.
-
maybe more effective when the bottle is painted black.
-
great idea for bots
-
...and what happens to the plastic bottles after a few months in the sun?
-
umm ok whats your watter presser
you are literally using a drinking straw!!!!!
just get a radiator and paint it black jeez, simpler, cheaper, and it use to worck on my grandpas roof in RUSSIA so u know it dosnt need a lot of sun!
