OK, What's wrong with this system? Would it really work? It's stated that its a most simple system. Water Heater

i dont see why not, that is pretty much how my friends pool is heated, loops of black poly pipe on the roof of the pool room and replace the barrel with the swimming pool and you pretty much have it, the only difference is he has to pump the water back up because of the 14' water drop rather than relying on themal expansion as in the diagram you linked too

Didn't read the link but with what garret mentioned, MEN was designing and using that sort of water heating system 35+ years ago.

I will say it would work if you need hot water away from the water heater.
But if you have a tin roof and if you wanted to supplement the electric or gas you use to heat your water heater then:
You can just mount the lines in the valleys of your roof, use a more permanent material for your lines and fill them with antifreeze or oil.
Then run that oil line into an extra sealed opening in your water heater (not the oil the whole line) you may want to use copper line inside the actual heater.
You won't have to worry about the liquid in the line freezing and you can put a shut off if you don't want the outside line "influencing" the water in the tank in the winter.
Gets plenty hot on the tin roof then the heat from the line makes the normal electric or gas power to heat the water work less often.
We have mostly eliminated the use of the hot water tank by using the little on demand electric heaters at the desired source. Uses electric only when you want the water hot and gives us some different water temps. Like at the kitchen sink and dishwasher the water comes out at 200 degrees, but at the showers it is 140. We are only using the hot water tank at the washing machine right now and we have it on a timer so it doesn't heat water when we are asleep or during peak use hours. Saves on electric bill as during peak use the almost double the rate.
Bottom line if you had this set-up on your roof with an oil or antifreeze line into your hot water tank you could heat water with out electric most of the time. No pump really require as the action of the colder liquid with the hotter liquid moves the liquid in the lines.

I would suggest some research between a 'heat pipe' and a 'thermosiphon' before implementing.
