Solar water heater

I have a solar water heater that is 4x10 with 300 of 1/2 copper pipe in it. home made. It is a direct system. The heated water is pushed with this pump 70 to the 80gal. storage tank through 3/4 cpvc pipe. I use a 12V 50 watt panel I bought from here also to power this pump. All works well with a 70 percent sunny day it will make 80 gal of 120 degree water. Im still tweaking it though. The only CON was the service. The site says call us and well help you. I did call and explain what I was doing and the guy here said to me  You are building a solar water heater and you want me to tell you what you need ? I was kinda taken back and did not appreciate the total lack of help. He told me to go read some more. So I had to figure it out on my own. Wouldnt even point me in the right direction. [edit: name calling removed] Panel and pump work well though.



Response from AltE:

At AltE we invest a significant amount of time and resources to train our technical sales staff to be as knowledgeable as possible about the renewable energy systems and components we offer to our customers. Like most of our customers, most of our technical sales folks are Do-It-Yourselfers themselves. They are passionate about assisting other Do-It-Yourselfers in creating renewable energy systems to meet their needs with the components we offer. However, they are not trained in how to create homemade versions of the components we offer nor design systems around homemade components.
