@digilogtech You …
@digilogtech You are correct. The tubing is actually 3/4″ and it has an internal diameter of 5/8″ (.625 inches). 100 feet of it holds about 1.6 gallons and 125 feet about 2 gallons. -
I love the design, …
I love the design, but 50′ of 1/2″ pipe is slightly over 1/2 gallon. -
@queball147 Yes, …
@queball147 Yes, the water would almost certainly get hotter. Currently (unenclosed) I am able to get hot water from about March through October. I will be enclosing the coiled tubing as fall and winter approach. (If I enclosed this type of tubing during the summer months – it would most likely get too hot and would be damaged). It’s rated up to 180 F (approx. 82.22 C) -
Hi would it make …
Hi would it make any diffrence if you put the pipe in a ceeled insulation box? you know like the sola iar cans, just a thuoght. -

Hiya
I’m planning to do this too in Spain with a 1.2m coil inside a matt black box with an acrylic double skin top. Your info is great but you don’t give any calcs for moving water, IE a direct system. Obviously when you move water through the tube the temp drops quickly. I’m hoping to regulate the flow by the 12 pump or throttling the tube so that I get warmed water continuously to trickle a small pool. What do you think? What happens to your water temp when its not static in the tubes? Ta -
@BooKittyRadley The …
@BooKittyRadley The diameter of the coil on the plywood is 3 feet. I would say the air temperature needs to be at least 85 F. (unless you enclose the coil in some way) -
Please tell me the …
Please tell me the diameter of the coil, as it measures now on the plywood.Also, how warm does it have to be outside for the water in the black hose to heat to 130 degrees in 30 minutes?
Thanks.

@StriderGTSAwesome man awesome, solar is heating free for the taking.

@kchedvilleAwesome, you’ve got it, now go out and do that for all your friends. Where are you located?

The water will rise …
The water will rise well above 48 degrees celsius (roughly 118 F). It will reach about 56 degrees celsius in 30 mins (132.8 F) and can reach 66 degrees celsius (150.8 F) in 60 to 90 mins. -
So you can get …
So you can get 48celsius water? Thats not hot! -
@kchedville add a …
@kchedville add a pressure escape in any water heating system to prevent bursts…. -

Update…i now have two boxes on the roof tied in series, on a good sunny day now, my water circulates at 140 degrees and stays hot till the next day. I’ve only applied electricity to my water heater 3times in the last month…. -

Well done. — I will do something like this -
@kchedville Yep, …
@kchedville Yep, that’s my problem. “LOVES” that dryer. -
Hey where do you …
Hey where do you get black hose like this?My idea is to heat my solar greenhouse by putting coils of this at the top of the greenhouse where it will be hot and hit by the sun, and then pump water from a container in the greenhouse through the coils and then back into the container. Will this work? And how many feet of coil would you suggest and how bit of a barrel of water?
A barrel of hot water would help heat the greenhouse through the cold nights in any number of ways.

if you have a …
if you have a friend that is throwing away an old fresnal lens from a rear projection tv, find a “warm spot” where the lens “heats up and put it over your pipes … you’ll find that it will increase the temp by a few degrees without melting the pipes… tell me how you go…by the way, the lens is what the picture will show up on with a rear projection tv.

@stangtrax trust me …
@stangtrax trust me…look into solar air heaters…and then after that think about copper…it has an even lower resistance than aluminum…now think about high temp painted copper….now think about coils of it…now think about solar air heaters….connecting the dots yet? Stay away from rubber…not smart…not healthy…not safe. -
the only reason I …
the only reason I wouldn’t use it is because of the winter where i am but if I lived in Florida etc. i would defenitly use this -
Dude. Thanks to you …
Dude. Thanks to you I now know how to heat water with solar. It is the same tech as it is with using pop cans as heat collectors in a solar heating panel…instead…use soft copper run in the same box and coiled within…as many coils as possible..insulate the box…you could even not bother uncoiling a brand new roll of soft copper. Might even to be able to fit nearly 1000 feet of copper. Top it off with aluminum flashing painted black and walla. Instant boiling water in the warm months. -
I made one using …
I made one using Sprinkler tubing which was suppose to be good to high temps, inclosed 200 feet inside an insulated box with acrylic cover, installed in on the roof,, half hour later, the box filled with water,,,, the tubing did not hold up,,,, it bursted… redone it all using soft copper tubing,,, on a sunney day, my heater stays filled with 110 degree water from the sun… -
@stangtrax – the …
@stangtrax – the black tubing is rated up to 180 degrees (Fahrenheit) -
? I am thinking of …
? I am thinking of doing this for my homes hot water, but can that black tubing handle temps over 140 deg. F ? -
so the water cames …
so the water cames out of the main you direct it into that tube it flows through it warms up and ends in your tank?
