in america we call 'em hot water heaters,..... so if you wanna give this guy shit for doing something constructive,.... learn how to speak the language first,...
So, you vented CFC ( an ozone layer killer ) to get a water heater......sorry, that may be a little harsh. Car rads. are good as heat exchangers There are some good passive panels that could have the heat removed using your spare rsd.
I am planning to build something like this. I have several questions. You said the temperature was 98 degrees. Was that the water temperature in the bottle or inside the heater? What was the outside air temperature that day? What are the dimensions of the box and heat exchanger? Also what was the angle of the box relative to the direction of the Sun? (90 degrees being ideal.)
You can paint all the crap you want black, and set it in the sun. Until somebody conducts a test to determine how much water, or other fluid, they have heated to a certain temp, in a certain amount of time, all of this is interesting theory. I see air heating boxes that raise temps 70 or 80 degrees, but they don't say how much they heated the air in a 10X12ft. room over a certain period of time. Yes the sun will heat but how practical is the heater??? I Want To Believe
like this but i find the heating element too small and therefor inefficient. On saving water though a new invention called ECO URINAL can be seen right here on you tube...SEARCH "eco urinal"......
I would coil a 1/2 household plastic pipe and coil it on the wall inside a 4 inch black pipe. The half inch pipe bathing in the 4 inch pipe filled with now hot water. boxed in like a air heater.
Brilliant to use the condenser from the back of an old refer unit. I don't know what they are made of, but I am sure the junk yard is full of them. Copper? Can you flush the refrigerant out to make it safe to use for domestic use? Not drinking, but bathing and washing dishes? Heating a hot tub? Looks easy to build. I am hazy though, do you put your water mass above or below the collector to get the thermosyphon effect? would the collector have to be on the roof of the hot tub or below it.
hey youre ok guy,simplly clear+to the point,id like to put something like this in a campervan?or R.V.as you say in the states lol,even harvest rainwater to tank under vehicle,panel like yours on roof,feeding to insulated tank, before reaching shower head ?would it have to be vented for hot days,when water aint running?would thermo syphon work?or use small 12v pump?why would bathing in it be no good?not drinking i can understand? any info greatly accepted ,..,thanks jim
There's no way you're getting continuous thermosiphon flow with the bottle sitting on the ground. It would have to be elevated above the panel so that you have a hot column of water going into it and a cool column coming out of it. Tip: Use a bucket with 2 bulkhead fittings from your local plumbing supply for a reservoir next time. That bottle is way too small.
Your off to a good start, instead of radiators try using copper tubing, ya its gonna cost you but you can make a good water heater using copper piping.
Put th tinfoil behind the fridge radiator to reflect the heat at it and paint the radiator black. Then next time for your experiment you cannot have the water boodle in the sun, it taints your numbers, put it inside a foam cooler or something. Your almost there!
but you want to absorb the light not reflect 80% of it with aluminum? red dark blue and green are good or even wood color is better if you don't have black.
Don't you image using a big bottle of water also may has even more function? such a clean and good energy free for us to enjoy . Make it real . :) Also think about mirrors.
Hi- I have a weekend shack remote from power, I used thermo-syphon to run a central- heating system. Old house radiators were connected in parallel to a water-jacketed wood stove, works great.Earlier I had an open fire, I used an old copper coil in the chimney to capture that from exhaist gases, and piped it to a 10- gallon tank, it got up to boiling point eventually .I found taht you only need about two inches of height difference in the tank input and output pipes to t-syphon.
@AtvProjects ABSOLUTELY NOT. This heater is for demonstration purposes only, do not attempt use this drinking or even bathing. I'm an engineering student And I built this to observe the operation of a thermo syphon.
@AtvProjects If you just want hot water to use for bathing or showering, best to get a solar shower for a couple of bucks or buy a black jerrycan and just put that outside in the sun
Great video...I converted my home to a net-zero solar powered home that uses no oil or gas...I made a video about it called, "Preparing for Peak Oil"....
its is estimated that the average household spends 90 dollars a month on heating water for domestic use. my family of six i estimate uses about 120 dollars per month for a capital expenditure of 1,440 dollars per annum. Only a fool would continue this practice.
i have purchased 400 feet of inexpensive
black plastic irrigation tubing, the kind used for water wells and irrigation,
@datzfast Be careful with the black tubing, the plasticiser is easily broken down by the suns rays and leeches into the water supply. But let me know if it works.
@datzfast I bought 300' of 1" poly abought 12 years ago and has been making hot water ever since. Now, I have built a thermal syphon box for a pre-waterheater tank, works like a champ!
I would not run drinking water through this, it will work fine for a pre-heat exchanger, fill this with a glycol mixture and wrap the copper line around a steel water tank and allow the heat to transfer into the tank, Freon can not be cleaned out of metal, and will leak into your drinking water same with radiators. Great job PhilETisMe
hot tea, hot cocoa, I appreciate that you are doing this type of experimenting, but you have to think about who is reading this and what they might do with your design and anything that might arise from it, So with that said, I would make sure that people knew not to drink the water from this, regardless of what you think they might not do. This is only to protect you bro. Also using this type of setup would be better as heat transfer with a exchange instead of direct water heating.
Once the refrigerant is vented from the coil there will be a small amount of lubricating oil within the coils. That can be cleaned out by using some kind of mineral spirits, flush well & rinse with clean water. Should be fine. The alternative is to run antifreeze & a heat exchanger in a potable water tank as part of the pressurized home water system.
@dic2uall the freon would only poise a suffocation risk, the fluorine molecule is tightly bound to the carbon molecule to such an extent that biochemically speaking it is for all practical purposes inert. i hope i dumbed the statement down enough for your understanding.
Yes this is true but it is run through copper which has the nice little property of absorbing anything it contacts with, which is why it is a very good conductor. any gas or fluid it contacts will be absorbed and leeched into anything else it contacts.
@TheDudeRulez09 actually copper tubing for refrigeration is a good idea because it can contain the freon gas without leaking through. it absorbs nothing. your more in danger from the lead solder in your copper drinking pipes
and faucet, thats why it is recomended to discard the first glass from the tap. the lead levels are higher..

OK, smart guy, I give up. You are correct. You are heating hot water. I understand. Why, I can't imagine, but OK, you are heating hot water. I think what you have designed is a "Solar water heater." But, I'll go with your reasoning. Now, maybe your next project could be a "Frozen water freezer." Oh, Wait a minute, the water would already be frozen! WTF? It is a real shame that you have the sense to make something, but don't have the intelligence to explain it. CZH
If you are educated, why not act like it and sound like it? It only takes a small amount of intelligence to sound like you have any. Heating hot water is redundant and the last time I checked, tin and aluminum are shown as different compounds on the periodic table. You failed english twice, and respectabilty without any means of recovering, infinite. Please try to get someone with a l;ittle sense to explain it to you. Personally, I think you are a dumb ass yankee that is beyond help.
Tin and Aluminum are not different compounds, the are different elements. Notice that I am not the only one who doesn't appreciate your comments, your first comment has two thumbs down. I'm glad you think I'm a "dumb ass yankee", it means you must be jealous of something I'm doing right, and if your from the south...well i'll just stop here.
@ZAGTHEGREAT I know its a year old, but your comment was just too cowardly to ignore. You failed at being a grammar nazi and failed to add anything to the discussion except making us pause to think about inbreeding southerners still mad their great gran'pappy's had to build their own shit w/o slavery.Maybe you can teach us how heating systems operate without paying an electric bill?I can see from your page your an expert on faggots?Im sorry but your penis expertise isnt needed here.XoXo'sCockBoy
@ZAGTHEGREAT I know this is a year old., but you sound like an ignorant redneck when you make Yankee comments. Tin and Aluminum are different ELEMENTS on the periodic table,COMPOUNDS are a combination of 2 or more ELEMENTS. However many people still call Aluminum foil Tin foil out of habit. You are old enough to know Tin came first. Hot water heater is redundant, but more people say that rather than just water heater. Also the man said he was an Engineering student, not and English Major.
This comment has received too many negative votesshow
If the water was already hot, why did you have to heat it? Wouldn't this be a "cold" water heater? Also, "tin foil" has not been manufactured in this country for decades now. It appears that you were using "aluminum foil" You should really, really learn to use the corect nomenclature.
First, it's a hot water heater, I've never heard of anything called a cold water heater. Second, if you spend your day prowling through youtube videos and nit pick the difference between tin foil and aluminum foil, I feel really bad for you. I'm an engineering student not a film editor or spell checker. I failed english twice, but I can design and build you anything from atomic weapons (I can even enrich uranium) to personal jet packs and beyond...assuming you put up the money.
@ZAGTHEGREAT No such thing as a cold water heater in the context you wrote. It would be a water cooler if the water was already hot. You don't use a heater to "cool" anything, do you? If so you must be from Iapetus.
Will this thing work in the winter time where the temp reaches 0 degrees? Does it hook up to a water tank? If so does the water tank need to be working?
Solar water heaters are very popular in China now, and the way they solve the problem of heating water with a solar heater in cold temperatures is by surrounding the tubes that heat the water with glass vacuum tubes.
If you expose a black coil in cold ambient temperatures, you won't get much solar heating.
Nice setup, you know that when you cut out the refer coils you released freon into the atmosphere causing a hole in the earth's ozone layer, I would not drink the hot water due to the residue from the freon, also the inside diameter is a little small for good water flow, the best material I have found is copper it conducts heat very well and comes in a variety of diameters and is easily found and chemical free!
@rbo350 the ozone hole you is a natural occurring phenomena. the triplet oxygen= ozone is a natural product formed by lightning passing through air. its not present at the poles because there is little lighting activity at the poles. that is why it is never mentioned in the news any longer. its about man made global heating nowadays. the ozone hole has and always will be present. its discovery was by accident made by orbiting satellites.ozone can be destroyed by man and rebuilt by storms
not a bad temperature reading seeing that you are reflecting the heat w/foil rather than absorbing it with black paint. You could glue some black paper in the or even use soot or charcoal to get the backing black. You want flat not reflective for efficiency. Nice super cheap design.
This comment has received too many negative votesshow
I am getting a little worried about all of you people trying to save the planet by the use of refridge coils for solar what did you do with the ozone killing gas that you released into the air was it recycled properly? I doubt it
I may not be able to control every junkyard in the u.s., but YOU are personally responsable for your protection or degradation of the environment. If I can challenge you to find a better way to make energy than this, then I have done something. You have little girls who are blessed with a father who takes the time to teach them about the power of alternative energy, about thinking outside the box- you'd better think HARD about what you're teaching them.
Another method Two points of method: (1) Two waters, separated, zero pressure and house pressure, and (2) Use principle of heat-exchange to take heat from zero pressure to house pressure by running copper metal tubing with house pressure, inside the zero pressure water. The copper metal does a very good job of transferring the heat, and many times better than plastic or rubber. Mixing sand and water in the zero pressure water is probably better. Thin aluminum may contain the zero pressure water.
the back of the frig is not a good place to get plumbing. The grid you have has has freon running through it. any and all water that goes through this unit will be contaminated with this.
The materials you used from the refrigerator are not designed for potable water. They are designed to give off heat to air. Might I suggest taking a water tank, painting it black, and putting it inside an old freezer and cover it with glass where the door went. cold in the bottom and hot out the top. The tank is made for water and the freezer is an insulated box. plumb it and your done.
I had no intentions of drinking the water, or even using it. I made this only for my own enjoyment and engineering practice. There is no way this small heater could even be considered to be used for a house it has a very slow flow rate.
Good project....Thumbs Up....

I am getting a little worried about all of you people trying to save the planet by the use of refridge coils for solar what did you do with the ozone killing gas that you released into the air was it recycled properly? I doubt it

look kid, you can go to junkyards and ask them to please reccle all the gas in the 500 old busted leaky circa 1950's fridges they got out back.
How about you go out and DO something for the planet instead of nitpick at people who are actually are doing something.

I may not be able to control every junkyard in the u.s., but YOU are personally responsable for your protection or degradation of the environment. If I can challenge you to find a better way to make energy than this, then I have done something. You have little girls who are blessed with a father who takes the time to teach them about the power of alternative energy, about thinking outside the box- you'd better think HARD about what you're teaching them.

Another method Two points of method: (1) Two waters, separated, zero pressure and house pressure, and (2) Use principle of heat-exchange to take heat from zero pressure to house pressure by running copper metal tubing with house pressure, inside the zero pressure water. The copper metal does a very good job of transferring the heat, and many times better than plastic or rubber. Mixing sand and water in the zero pressure water is probably better. Thin aluminum may contain the zero pressure water.

the back of the frig is not a good place to get plumbing. The grid you have has has freon running through it. any and all water that goes through this unit will be contaminated with this.

The materials you used from the refrigerator are not designed for potable water. They are designed to give off heat to air. Might I suggest taking a water tank, painting it black, and putting it inside an old freezer and cover it with glass where the door went. cold in the bottom and hot out the top. The tank is made for water and the freezer is an insulated box. plumb it and your done.

I had no intentions of drinking the water, or even using it. I made this only for my own enjoyment and engineering practice. There is no way this small heater could even be considered to be used for a house it has a very slow flow rate.

invalidmemberaccount: Sounds like an engineer. I would love to see; this, you mentioned, in a instructional video. Sounds like it would work.
