Solar water heater

[Jamesh]

Whilst in my travels this morning I saw a fiat pvc with a loop of 100mm black piping around the perimeter of its roof rack. It had a valve over the back door.
I can only summise it's a solar shower did look ugly tbh.

Not sure to it's efficiently either.

Cheers James

It's the way to go I think. I've seen one made as a spiral coiled into a circle that worked well and holds more water than you think.

I made a solar siphon last spring and although it worked well it was a faff making the tank and how everything had to be positioned to work.

It got the 10L water up to nearly 50c in march though and it was only on for a couple of hours or so, imagine the performance in mid summer... Or Spain.

Perhaps this heat exchanger with a small pump tapped into the van water heater tank would work well
