Hello,
I was thinking about building a diy solar water heating system using the box storage heat transfer system to my existing water heater and was wondering if anyone has tried it.
If so did it work and was there a savings on the utility bill?
Thank you,
Steve K in Phoenix, AZ

What is a "box storage heat transfer system"?

Heating a storage tank full of water with solar hot water, then running around 300 feet of pex pipe through it, preheating the water before it reaches the existing water heater.
I saw a plan for it and was wondering if it really worked.

Thanks for the clarification. I'm sure there are members who have done that, and hopefully one will come on. I'm not one of them.

Dig a little further at the BuldItSolar site and you'll find examples of completed systems.

Hell yeah it works, saving me 30 to 50 dollars monthly.  (depending on sunshine of course)...  I'm in Texas. thats not much of a problem.  I have a build of mine on this site somewhere you used to could find by clickin on my name in blue.  Not sure if it's still there, haven't been on in quite a while.

I built one similar to the one on Build It Solar and save about $40 per month in water heating costs.  Build a collector to heat water in a storage box and then loop your 300 feet of pex in the storage box and into your water heater.  You will be amazed at how crafty you are ;-) IMG_0788.jpg
