SOLAR HOT WATER 2 DIY USING BLACK WATER HOSE SOLAR WATER HEATER SUN POWER

What if you had a circulating pump on the cold side pumping thru the hose going back to the Hot side of the Water tank, put it on a timer and set it to turn off at night and back on during sunlight time? What are you thoughts on that Dan?....Would the pump still pump under the pressure of the incoming cold water in the Tank? Maybe use a Solar Powered Pump?

lots of hose !!!,.... dudes and dudettes

I don't think running glycol through a water heater is such a good idea ;)

I love this idea - we did something similar when I was younger and used it to heat an outdoor shower. One question though. Why not coil the smaller, more flexible hose inside the open area of the larger hose? This seems like a more efficient use of space.

Great video,I live in Ecuador in the coast we allways have sun,now i will allways have hot water, THANK YOU

I made water using a similar concept. I use it to heat the water for my house. It heats about 80 gallons (300 liters) up to 135 F (55) C on sunny days. I used PVC and other cheap materials. I made a youtube video about it:

how would that work in the winter when my hose always freezes?

I'd like to make such thing , but unfortunately i live in Netherlands where it mostly rain :/

I would not drink water from a hose especially when it is new.

Yes. The first time I made the mistake and almost burned myself with water from a hose left in the afternoon in the summer in Texas. Now it is the end of November and the water is warm enough to take a shower in the afternoon of a sunny day! We get a lot of sunshine in South Texas and I am hoping to be able to do it thru the winter. If it works I will build a more permanent Solar water heater using 2 inch galvanized pipes in a box covered with glass.
