I also live in Florida (orlando area). I DIYed a standard hot water heater with a used standard collector panel, 10w PV panel and pump. It took a few shots to get the plumming right but it works great, sometimes too great.
Very cool video. I wonder about the extra weight being a problem for small structures like the carport. Do you have any ballpark estimates on how many pounds a hose like that will hold? I imagine there must be a good general formula, like.. hose X diameter multiplied by Y feet = Z gallons.,, I just never thought about it before.
You could have nested the smaller coil inside of the larger coil, and saved some space on your roof. That would have allowed you to put another collector up there.
There U are right, It is just that If U may want to store it, Try this out in my channel in YouTube at debeshbhattarai a complete illustrations for storage in Plastic Barrel as well
This was entertaining as well as informative. Thanks. Now i just need to get out in the 110 degree weather and start to work. Does anyone have some SAE 30.. I might as well get a tan while at it so that I will look a extra 10 years older in 3 years. LOL.. Thanks guys...
@thestirfrychicken its one thing to blatantly voice off topic opinions but to end a sentence like "Or not, it's your life." seems like you are trying to shame people into action which is quite sad.
I live in Arizona and switch off my hot water heater at the breaker box throughout the summer. My family still enjoys their more than warm showers. Who wants a "HOT" shower when it's 100 degrees plus outside anyway?
Why can't people have their water heaters painted flat black and simply placed outside in the sun 8 months out of the year? Where I live, it doesn't even go below 80 degrees at night! I don't think it would ever "turn on" this whole time.
@timalto1 . This would be an ideal location to do such. Google 'Batch Heater' and youll see how it can be done even in northern climates using a water heater tank .
@GREENPOWERSCIENCE So couldn't you also use the heated water and run it over the heated part of a Stirling engine or some kind of heat engine to provide power for stuff like battery arrays and such?
Caution : THe Suns UV light will break down the walls of the plastic tubing until eventually it will leak. Wrapping the entire roll with sheets of heavy duty tin foil painted flat black is a good solution ...and placing everything in a wooden box with glass over the top tightly sealed is even better if you want to REALLY increase the efficiency.
I've always wondered if that black pvc could leach chemicals into the water, especially when being heated. We had heater on our garage roof for our pool just like this. The water always came out hot and smelling like plastic. I would have never considered drinking it.
I agree. I think using copper piping painted black would give you the best result without contamination, however it would require more initial cost, but offer much longer, superior results.
@jayrod28542 That black pvc pipe that they are using is the same pipe that millions of people in this country use in their underground wells. everyone in my family has a well and have been using some of that pipe for twenty years. Every couple years or so the county tests everyones well water free. Our water quality is still far superior to the city water. However, the pipe when new does have a smell, but run your pump for a few hours and it goes away entirely.
@davidclaywest The box is a good idea the tin foil is not. Aluminum to plastic has a very poor transfer. Most polytube is good for 5-7 years of UV exposure. The hose on our roof is going on 5 and it only popped loose once from freezing solid. Poor connection on my part.
Using a box covered with a double-pane window frame will greatly speed up the heating by radiation alone ; the purpose of the blackened h.d. tin foil wrapped once around the tubing coil is just for UV protection making it a very long lasting/permanent installation and doesnt need to be used for heat conduction purposes. Going with Pex-B coiled tubing will give you up to 200 f. at 100 psig . Im surprised your poly tubing has lasted 5 years in UV light and will fail eventually, but good idea.
Kinda seems a little low tech, but you might be able to build some kinda optical light concentration/focusing mechanism to maximize your available light. Additionally you might also use some sort of wind power pump system to a cistern so you could use gravity to pressurise the system.
What is left for the Syrian regime, the offender and the Iranian regime after the terrorist that committed the massacres against the Syrian people, and now discovered the mass graves of the demonstrators innocent to remain silent about these crimes will come grief to international regulations because it is set on violence and frustration in the hearts of the peoples of the international silence and double standards, and this is more dangerous than Global warming

Dan, did you test this to see what the temp would remain at while it was continusly flowing? also in louisiana I know of a guy that has a 4" pvc pipe in the peak of his attic (gable roof) it runs the whole lenght of his roof about 45' it it piped to his hot water inlet. but he does have a bypass for cold winter days. I think if you use a simple set up of thermocuples and switches you could set it up to test inlet water from outside and the temp of water in attic pipe to operate the bypass automa
I used this same idea to help heat the water in our dough boy pool. Used a small pump to circulate the water up through the hose coiled up on the roof, then back into the pool. It raised it a few degrees which made it more comfortable...
@vewdew3 Hello. A parabolic reflector concentrates the reflected light at a certain distance from its surface, thus creating a focal spot. If we placed black tubing directly on the surface of a parabolic mirror the tubing would not be with in the mirrors focal spot, it would be just like placing it on a flat mirror.
If we want to increase the efficiency of the heat transfer (for colder climates) we could cover the tubes with glass panes, thus creating a greenhouse to trap in the infrared light.
So part one was the "How Not To" and now we get to figure out who has the brains. Too funny. (Especially the part of it being so cold in Florida while I watch during winter in Minnesota.)
FYI: white pvc pipe disintegrates from uv exposure. any air bubbles in the system will also cause hotspots which will cause the pipes to fail prematurely. wrap the pvc pipe with electrical tape or foam pipe insulation to prevent uv damage. you might also want to add a backflow valve between the coils and the tank to prevent a leak from draining the whole system and damaging the tank.
The ovalisation might make the corners an issue, so, you could lay out the pattern, mark it, and just ovalise 'the straights' leaving the curves in round x-section. Alternatively, you could make the exits to the 'super-hooks' so the oval is locked perpendicular to the ground on entrance and exit to the (now somewhat evolved) 'hooks'. Such hooks are definitely something that could be sold for the purpose of laying out rooftop solar-hose. But no patent now! ;)
NB. When I said meat-hooks, that was just an analogy. Obviously, if you used meat-hooks or anything that did not actually ATTACH to the structure somehow, if it came free whilst laying out the hose, it could end up being fired at you. So tethers would be needed to prevent hooks flying. Suppose that mentioning tethers shows another option for laying out the hose. Just wire it to bolts to the structure.
Ovalised hose would be better (more surface to sun AND to roof for same (or even less) volume). Run hose through rollers to crsh. Use hooks (like meat-hooks hooked onto edges of roof to ) to wind hose around. Can do any pattern you want, but same as refrigerator radiator would be easy and good. Due to hose, the end shape would not be straight lines, but it would work. Could make tight bends w a better hook w (insulated) box-section on it to compress the curve. Like pinching rubber-bands.
my father did this over 25 years ago. It worked fine but the problem was in the connectors. They did leak about 20 years in and the damage from the water was pretty bad and expensive. It was an effective system to heat the pool up here in montreal, canada. Eliminate connectors as much a possible or risk expensive water damage.
40 years ago my father made a very similar construction, when we built our family summerhouse. Still in use although tried vandalized along the way. We're now working on a much larger parallel tube construction that holds 40-50l (inlet in the bottom, outlet at the top and placed on black bulged roof). Come summer the project continues.
Heat permeates into the ground steadily, so the water in the hose will constantly be heated, even on cold and cloudy days. It also removes a lot of clutter.
Just seems like a much more efficient idea, even if you do need a pump.
silly question- does the hot water heater know there is 120 degree water ready to enter the system? If the hot water tank is pressurized how do the elements/thermostat know there is a bunch of "reserve" hot water? How does this save electricity other than during the ramp up cycle after you take a shower? Or is that the extent of the savings? Thanks
@derekstech You have no idea what you are talking about. 100 feet of 1" hose holds 15 gallons. He is correct in the amount of water the system holds. FURTHER MORE, PAINTING THE top of a barrel black will do nothing. LOL
I had a thought when I typed the last one. Other methods might include (but maybe not as cheap as hose) using copper pipe, bent into similar tiles may offer a more robust permanent solution? either way, I think my method of constructing your system as tiled units would make for a more easily scalable way of getting hot water on the cheap.... Cheap I like, I am Scottish and you know what they say, copper wire was invented by two Scotsmen fighting over a penny! Hope you try my idea.
This is a great concept! You could also try making 1 x 1 m tiles with the tubing snaked over and fixed to some sort of wood, perhaps ply wood. Pre-paint the wood black then use (and I cant remember the name of it) metal strips with holes to loop over the hose to hold it down (strip also painted black). At the inlet and outlet some sot of quick connect could be positioned to connect the tiles into a continuous hose. Thus, you could "tile" your whole roof and really collect a lot of energy! More.
@soapolice well when ur average weather your used to 80-90 degrees all the time and the weather shoots down all the sudden to 30-40 degrees, then ya thats pretty cold. Kinda like when u get outta the shower and ur lil nuts shoot into your ass cavity. Prolly happens to you without the shower tho
you guys are awesome Dan, but i thought we were supposed to see the shower in action, wif Denise, fun to see just average folks just wanting to have fun, good chemistry people
(cont. #2) On top of that, the maximum operating temperature for PVC is 140F, so they're exceeding that as well.
I don't know if encouraging people to disregard code is a crime, but it's certainly very immoral to encourage people to do something that could cause irreparable injury without warning them of the risks.
(cont. #1) Thanks for making me watch the video again, though. They're getting 120F water in 30 minutes in winter, and they said they can get "well over 140F" if they let it sit for 2+ hours.
Guess what? CODE SAYS IT CAN ONLY BE 120F. 140F water will give you a 2nd degree burn in 3 seconds and a 3rd degree burn in 5 seconds. Just imagine what using that solar-only hot water shower would do to you! With temps "well over 140F," you might as well pour a steaming cup of coffee on yourself.
thanks, grate vid GPS... And pay no attention to JTGOB2, apparently he has about as much expertise about this stuff as a rock.. checked his page and the only thing there is a bunch of nothing, bet dollars to doughnuts, he got his posting information from a blog off another site.. take notes JT..1-they live in Florida, no hard freezing..2-they state to flush the system regularly ..3-WHERE DO THEY SAY ANYTHING ABOUT FOAM INSULATION OR REWIRING THEIR HOME??... Now who is looking so stupid???
@jensage58 "JTGOB2, apparently he has about as much expertise about this stuff as a rock"
#1 I'm a NABCEP-certified PV & Thermal installer.
#2 Most watchers of this video do not live in Florida.
#3 Even if someone does live in FL/CA, it freezes, even in Florida and California. See, for example, a freeze in 1913 knocked out thousands of ICS solar hot water systems in Southern California. Also, in the video, they said it dropped to 35F just hours prior to the recording.
@jensage58 Pay no attention to him because why? Because everything that he said was 100% correct? I am a seasoned solar installer myself, and I can recognize someone who knows what they're talking about. All of what JTGOB2 said was legit.
Oh, and just to give you all an idea of what can happen when you try to do stuff that you have no business doing (or when you employ idiots), I once knew a guy that got foam insulation installed in his home, and guess what happened? It somehow caught fire, presumably because the foam itself undergoes an exothermic reaction when sprayed or something electricity-related.
Guess how much that home was worth? USD$15 mil. Lost in the fire were a Picasso, a Rembrandt, and other irreplaceable items.
Great idea until it freezes and shoots water all over your yard. Better hope you're not on Christmas vacation when it happens, otherwise the city won't be too happy.
And then you go on to say that you should use glycol if you live in a cold climate. Guess what glycol degrades into? Acid that will eat your hose. On top of that, there is, of course UV that is already attacking the hose.
Do-it-yourself solar and cutting corners on solar is about as stupid as DIY electrical work or cutting corners on electrical work. Videos like this are so stupid that it's not even funny.
Seriously, people, if you want solar, find someone that knows what they're doing. Cheap solar thermal can flood your home, and cheap solar PV can burn it down. Attempting to do it yourself or encouraging others to do so is beyond careless.
We placed it all the hose in a shallow box with a black painted sides and bottom about 6 feet across with plastic covering to hold the heat in. Also haveing it angled to catch more light. Does a fairly good job. Most folk think it takes the place of a hotwater heater, but it only suppose to raise the temperature high enought so that the heater uses less energy to heat the water. However on good days it doesn't have to use any energy at all.
Great video, really got my gears turning. I live in north east PA, ( not the Poconos, for all you critics ). I'm gonna work on solar water heater after I get done with solar power system. Thanks for sharing your expertise and ignore the idiots and their wise cracks.
It looks like a Saturn. I own a 2002 Saturn SL2, 4-door, 5 speed stick, with 88K miles. With conservative driving I consistently get 30 mpg in the city and 40mpg on the highway, plus or minus 2 mpg or so, depending on conditions. My highest city miles was 34 mpg. My highest highway mileage was 44 mpg (warm spring, no AC). My lowest city mileage was 24 mpg (winter, lots of idling & low gear due to ice) and my lowest highway mileage was 34 mpg (75 mph with AC and headwind).
I'd use copper piping and flush the hose with chlorinated water quite often, to keep bacteria from growing. You don't want to have a shower and smell like a swamp.
Great video. I would maybe work out your lines a little better and use large cards with what you want to say written on those because it seems like at times, you forget what you wanted to say and it comes out unprofessional. I've taken public speaking in college so I know how hard it is to speak on camera, especially off the cuff type speaking. I am pretty sure that on most of those on HGTV shows, they do work out most of what they want to say. Don't be afraid to redo scenes and edit later.
uhhhhh,,,,CPVC is for Uhhhh,,,HOT Water. Every man does what he can do to save a buck,, nice job and keep it up. I'm looking at the same idea to heat the water for my Tilapia tanks.
Polyvinylchloride or PVC is NOT RATED FOR DOMESTIC WATER USE. ABS is the proper rated water conduit as it DOES NOT LEACH TOXIC CHEMICALS INTO YOUR WATER-like the PVC does.
A cross built out of 4 inch by 4 inch thick timber half way cut out in the midle for a perfect cross so they sit inside each other and lay flat , with holes drilled out the size of your tubing would help you spiral your hose perfectly and keep it housed better ,just 1 inch apart should suffice , also allowing more of the tubing to absorb the suns heat ( including the sides of the tubing , if you used much longer tubing you could quite easily fill the carport roof completely , giving more volume.
In the summertime here in Phoenix AZ, hot water normally comes out of the COLD water faucet. The hot water from the COLD water faucet is hotter than the "hot" water coming out of the HOT water faucet.
So, right at about June 15th, I switch the COLD and HOT handles on all the water faucets in the house. Then around mid-October, I switch the handles again because by this point in the year Hot water comes out of the Hot water faucet again, and cold water from the Cold water faucet.
That's why women are called the better half...

So tethers would be needed to prevent hooks flying. Suppose that mentioning tethers shows another option for laying out the hose. Just wire it to bolts to the structure.

Ovalised hose would be better (more surface to sun AND to roof for same (or even less) volume). Run hose through rollers to crsh. Use hooks (like meat-hooks hooked onto edges of roof to ) to wind hose around. Can do any pattern you want, but same as refrigerator radiator would be easy and good. Due to hose, the end shape would not be straight lines, but it would work. Could make tight bends w a better hook w (insulated) box-section on it to compress the curve. Like pinching rubber-bands.

my father did this over 25 years ago. It worked fine but the problem was in the connectors. They did leak about 20 years in and the damage from the water was pretty bad and expensive. It was an effective system to heat the pool up here in montreal, canada. Eliminate connectors as much a possible or risk expensive water damage.

40 years ago my father made a very similar construction, when we built our family summerhouse. Still in use although tried vandalized along the way. We're now working on a much larger parallel tube construction that holds 40-50l (inlet in the bottom, outlet at the top and placed on black bulged roof). Come summer the project continues.

If you have this run in series with a pool pump, wouldn't it add too much friction and seriously reduce the rate of flow?
Victord2000 1 year ago
Why don't you bury the hose underground?
Heat permeates into the ground steadily, so the water in the hose will constantly be heated, even on cold and cloudy days. It also removes a lot of clutter.
Just seems like a much more efficient idea, even if you do need a pump.

silly question- does the hot water heater know there is 120 degree water ready to enter the system? If the hot water tank is pressurized how do the elements/thermostat know there is a bunch of "reserve" hot water? How does this save electricity other than during the ramp up cycle after you take a shower? Or is that the extent of the savings? Thanks

I had a thought when I typed the last one. Other methods might include (but maybe not as cheap as hose) using copper pipe, bent into similar tiles may offer a more robust permanent solution? either way, I think my method of constructing your system as tiled units would make for a more easily scalable way of getting hot water on the cheap.... Cheap I like, I am Scottish and you know what they say, copper wire was invented by two Scotsmen fighting over a penny! Hope you try my idea.

This is a great concept! You could also try making 1 x 1 m tiles with the tubing snaked over and fixed to some sort of wood, perhaps ply wood. Pre-paint the wood black then use (and I cant remember the name of it) metal strips with holes to loop over the hose to hold it down (strip also painted black). At the inlet and outlet some sot of quick connect could be positioned to connect the tiles into a continuous hose. Thus, you could "tile" your whole roof and really collect a lot of energy! More.

(cont. #2) On top of that, the maximum operating temperature for PVC is 140F, so they're exceeding that as well.
I don't know if encouraging people to disregard code is a crime, but it's certainly very immoral to encourage people to do something that could cause irreparable injury without warning them of the risks.
JTGOB2 1 year ago
(cont. #1) Thanks for making me watch the video again, though. They're getting 120F water in 30 minutes in winter, and they said they can get "well over 140F" if they let it sit for 2+ hours.
Guess what? CODE SAYS IT CAN ONLY BE 120F. 140F water will give you a 2nd degree burn in 3 seconds and a 3rd degree burn in 5 seconds. Just imagine what using that solar-only hot water shower would do to you! With temps "well over 140F," you might as well pour a steaming cup of coffee on yourself.

#3 Even if someone does live in FL/CA, it freezes, even in Florida and California. See, for example, a freeze in 1913 knocked out thousands of ICS solar hot water systems in Southern California. Also, in the video, they said it dropped to 35F just hours prior to the recording.

Oh, and just to give you all an idea of what can happen when you try to do stuff that you have no business doing (or when you employ idiots), I once knew a guy that got foam insulation installed in his home, and guess what happened? It somehow caught fire, presumably because the foam itself undergoes an exothermic reaction when sprayed or something electricity-related.
Guess how much that home was worth? USD$15 mil. Lost in the fire were a Picasso, a Rembrandt, and other irreplaceable items.

Great idea until it freezes and shoots water all over your yard. Better hope you're not on Christmas vacation when it happens, otherwise the city won't be too happy.
And then you go on to say that you should use glycol if you live in a cold climate. Guess what glycol degrades into? Acid that will eat your hose. On top of that, there is, of course UV that is already attacking the hose.

Do-it-yourself solar and cutting corners on solar is about as stupid as DIY electrical work or cutting corners on electrical work. Videos like this are so stupid that it's not even funny.
Seriously, people, if you want solar, find someone that knows what they're doing. Cheap solar thermal can flood your home, and cheap solar PV can burn it down. Attempting to do it yourself or encouraging others to do so is beyond careless.

We did this with a laarge hose complex, so even on the not so sunny days, it makes the water going in warm.
fightoflife4 1 year ago
We placed it all the hose in a shallow box with a black painted sides and bottom about 6 feet across with plastic covering to hold the heat in. Also haveing it angled to catch more light. Does a fairly good job. Most folk think it takes the place of a hotwater heater, but it only suppose to raise the temperature high enought so that the heater uses less energy to heat the water. However on good days it doesn't have to use any energy at all.

My highest highway mileage was 44 mpg (warm spring, no AC). My lowest city mileage was 24 mpg (winter, lots of idling & low gear due to ice) and my lowest highway mileage was 34 mpg (75 mph with AC and headwind).

A cross built out of 4 inch by 4 inch thick timber half way cut out in the midle for a perfect cross so they sit inside each other and lay flat , with holes drilled out the size of your tubing would help you spiral your hose perfectly and keep it housed better ,just 1 inch apart should suffice , also allowing more of the tubing to absorb the suns heat ( including the sides of the tubing , if you used much longer tubing you could quite easily fill the carport roof completely , giving more volume.

In the summertime here in Phoenix AZ, hot water normally comes out of the COLD water faucet. The hot water from the COLD water faucet is hotter than the "hot" water coming out of the HOT water faucet.
So, right at about June 15th, I switch the COLD and HOT handles on all the water faucets in the house. Then around mid-October, I switch the handles again because by this point in the year Hot water comes out of the Hot water faucet again, and cold water from the Cold water faucet.
