Hes off again !
Why pay for gas all year round ?
Build a box
Put 10m of bent up copper 10mm pipe in it .
-
and then what ??
-
Its coming , CIU playin up !
-
I've seen this on you tube, but mostly the Americans.
There was also a chap who bent at around his chimney so I went and bought some and thought ild give it a try. Never got round to it
-
Line box with steel sheet
Paint black and cover with plexi glass
-
is it a new modern art decoration of some sort ;D
-
;D ;D ;D
Its a box full of black magic :o
Watch this now .......pure magic from Febuary Sun !
-
Water in .......MAGIC......Water out ;)
-
is that going on a van roof or something ;D. I'm intrigued but not getting what you intend to do with it.
-
Yeah , I got a little bit of space left by the solar panels ;D ;D
-
Colonic irrigation my friend , everybodys doin it ;D ;D ;D
-
I was going to set this up but switch for a chimnea and leave it to fill my tank late evening

So kinda intrigued as to how your going to use it? In same way and fill your tank up from ibc or use on roof and loop the water through as you use it, kinda swapping it for a combi boiler
-
and then what ??
Shhhh.
I'm trying to watch the telly in the background.

There are much better ways than that, more efficient if you google search thoroughly

Enlighten me please , this was just one that i came across that looked do able without lots of hassle .

Yeh, they're called gas & electricity ;D

My immediate reaction is that what's required is as much surface area as possible so your setup absorbs as much solar energy as possible. I'd find a used radiator, flush it out very well, paint it with matt black paint then put it in a case with a used double glazed panel in front of it.
Your 10m x 1cm setup has a total area of 0.1square metres.
A rough guide to solar energy is about 1Kw/m^2. The specific heat capacity of water is about 4,200Joules/degC.
So if you have 0.1m^2 of pipe that's 100% efficient, you'll be able to raise the temperature of one litre of water by 0.1 x 1000w / 4,200 = 2 hundredths of a degree centigrade every second. Pretty sure that maths is correct but I'm open to correction.
You need a bigger area. Even a tiny 60cm x 30cm radiator would be nearly double the area and would all be dead square on to the sunlight.

When I used to work on the scuba diving boats out of Eilat in Israel at the end of the day there was a hose-pipe laid out on the pontoon. We used to take a shower with the water in that hose, straight out of it, no shower head or anything. The water was toasty warm every day, it had been sat in the pipe for 10 hours or so and it heated the water up luverlee.
The weather was +40°C - 45°C though.
This system just hasn't got the oomph, and we haven't got the weather. It'll take 25 minutes to raise one litre of water by one °C in weather that we never experience in this country.
Back to the drawing board.

I know as you say it is almost not doable , it deff is not with what i have anyway , i had all but the copper pipe laying in the shed so i only stand to have wasted £23 so far .
All i know is that i managed to get water almost instantly from 18c to 40c with poor Febuary sun , and that was with a very poor flow rate , nothing like the 1.7Lpm that i need at brush head , on demand is not happening thats for sure !
I have a couple of ideas in my nutty head that wont cost to try , any thoughts welcome , i am not overly bothered by hot in the summer , its always been a comfort thing in the winter for me anyhow , if i can have it even a bit warm without buying gas why shouldnt i eh ?

Nah , not listening :P
I Know what you say about the hose , i have on times had it laid out for as little as 5 mins and the pressure build and heat has been shocking , and that has been with yellow 6 mm .
I honestly think that if we could safely use black hose it would be a game changer , just asking for troublr though .
Im gonna keep on to see what i can achieve , nothing to lose is there ?

A couple of my friends did something similar a couple of years back for those Bestway swimming/paddling pools. One made up a box similar to yours but much larger & put it on his garage roof, the other got some black irrigation hose & coiled it up on his garage roof. But they were constantly being re-circulated back into the pool via the filter pump.

Only face by the fact it will look absolutely s**t on top of your van.
How can you try and justify a good price for a job & then turn up with that on top your van? Makes you look a cheapskate.

If watched or seen the video highlighted on my previous post on this thread he used fire to heat the water and circulated it in maybe 50 litres of water.
So possibly do similar and run a chimnea with a large chimney) if you have one and leave it to fill an insulated tank over night and then do a tank transfer before work. Pick up scrap wood on your travels so the fuel is free as well perhaps
-
Oh come on Nathan...really? I thought the immersion was crazy enough but heating over a chimnea and picking up scraps of wood?
I'd love hot but not that much! If I ever want it that bad I think I'd just have to pay the going rate just as Dazmond has.
-
This is why i carry on and do it , i love the banter , it cant be done my arse , it will look stupid !
I dont care what it looks like to be fair , people wont even see it on the roof , they didnt see the solar panels , and tbh i think if people see this sort of thing they kind of admire it ;D ;D ;D

It's a project and who doesn't love a good project other than work and the mundane everyday day duties etc. Lol, picking up scraps of wood. I have customers who are tree surgeons and I'm sure I could come to some arrangement with them etc or yes, if I wanted to I could source plenty of scrap wood. But this isn't my project, just offering up ideas rather than being negative and thinking inside the box.
I do laugh how people tell me my own findings are wrong just because they can't achieve what I'm able to do, or didn't have the hindsight to get a larger tank and reserve water because they limited themselves to a 300 or 350ltr tank. Also what's up with a basic way of using immersion heaters for hot water rather than buying a fancy 5grand system with more possibilities of things going wrong down the line

Good idea.
You could carve some wood to use as a dog-muck-picker-upperer and then burn the offending stick to heat the water.
Hey, you could even burn the dog mucks whilst you're at it. I wonder what sort of heat they give out.
Best not do it if the wife's got a line full of washing out though.

Its just that this is exactly what my box will be doing if it does not work on the van .

Its only a little pool so should be ok.
In my last house i had a pool that took 12500 L to fill , the missus only sent me out to get the kids a paddler ;D ;D ;D
-
Jeff brimble did similar i think with a immersion water tank..... Thats all i know lol

each to their own but id rather spend my spare time bodybuilding/drumming(or anything else!) than faffing about with DIY stuff.......

It did work for both but I'm not sure to what degree.

I see what you did there ;)

I would but the van is too small ;D
