Finally got my solar water heater installed

I have rainwater collection, solar panels and now I made my first solar water heater.

I went to the dump and bought an old water heater for 15 bucks. I peeled off the shell with a hammer "easier than I thought", flushed the tank out with water, put it in a nook on the south side of the house, ran flex pipe to the inside water heater "30 minutes", turned off the gas "no longer needed" and I was done. I had hot water in one hour. I will build an insulated case with a glass door for the winter. My total cost was 108 dollars.

Turns out that 1/2 of all houses in Florida and California had solar water heaters in 1941. That is so cool.
