Off
camping tomorrow so decided to purchase another solar shower to supply the
camp with heated water. I purchased one from Super Cheap Auto. Something I never do is read instructions so but in this case I did. Interesting results.
On the package containing the shower it has the following.
1. Fill with water, Do not overfill past line marked on bag
2. Place clear side up on a flat, stable surface that is exposed to direct sunlight.
Etc …..
On the Solar Shower
1. Fill
camp shower bag with water
2. Place on a flat surface with black side exposed to direct sunlight.
Etc ….
Interesting to note that not even the manufacturer or the quality control in Super Cheap know which way is up.
Will spend my time on Fraser Island wondering if I am getting the maximum effect from the suns rays.

Hi Gazza , how come we techo types never read instructions ? Too impatient I imagine , used my solar heater last W/E and I don't think it makes much difference which side as the ambient temp is bloody hot either way.
Fitted new rear springs and shocks last night, EFS got through Marks mate . about 50 mm higher but will settle I imagine and the OEMs were sagging a bit as
well . Definately firmer ride with reduced body roll . P**ck of a job with reduced work space but hands healing nicely! Have a good trip and see you back at the salt mines.
Cheers Dave L.

I tend to keep the black side down, so the water warmed by the black surface then rises, creating a better thermal circulation. If the black side is at the top, then the hot water collects at the top, reducing circulation.
I also try to place some insulating medium between the sac and the ground to reduce heat transfer away from the sac.
But in practice, I've found that at the end of the day, you get a hot shower either way.
