I noticed you plumbed your hot outlet and cold inlet from the same end. Looking at the interior diagram of a gas water heater, there's dip tube (cold inlet) that is longer than the hot outlet tube. How did you determine which outlet was cold and hot so you could turn the hot (short) up and cold (long) down? Also why didn't you opt to plumb your hot outlet from the bottom drain valve? (I saw a diagram on this. Wondered if it would make a difference in heat level.)

Before I striped the cover off the tank I marked the cold pipe so I knew which pipe to use for hot and cold. On my tank in the solar heater the inlet(cold/long pipe)

is on the bottom, and the (hot/short pipe) is on the top. Also,the bottom of the tank is lower than the top inside the box.

how much does it cool down over night ?

[BACKYARDSOLAR]

In the summer, It will drop from around 140 to about 120/110 deg. in 8-12hrs.

being covered with a hot tub cover. In the winter I noticed it drops from 120 to 95 deg, in about 5 hrs. In the winter I try to take showers right when the sun gos down, to get the water while it at its hottest. If you haven't already, check out Part 3' of my videos for more info. Thanks for the comment. Todd

lol.. good stuff amigo.. But where are you at so far? :)

[BACKYARDSOLAR]

Ok, Ok.... Sorry I know I used the term

"Here's where I'm at so far" to many times. I will be making "Part 3" here real soon, and I will have all the details on how well the unit is doing.

Amazing! Human ingenuity, I love it.

Looks pretty hot.

[Teddybearcop48]

Wonderful. I wonder what it would work like in the winter time... THANKS !!

I love your heater, you should check out the solar water heater I built for northern vermont. we get much less sun so it had to be a different design. the video is on my page, let me know what you think.

good morning mister ! you are very bravo !! with the solar energy compliment from italy to danilo !!!

[wwf1968]

good, simple design 

[Progrocker70]

Was wondering, do you need to leave the anode rod in the tank or do you remove it? Is it still needed to prevent inside tank corrosion? Also do you use the same relief valve that came with the heater and can it handle the temperature and internal pressure the tank would get being inside a heated box?

Isn't it truly amazing that everyone with a conventional water heater isn't using one of these in place of it or as a preheater.
