    Guys, your product range is incredible. Where are your modules and components manufactured?

    I was able to cop an entire thermal solar system with 4 panels. 50gal indirect tank (battery) even a high end taco stainless steel pump ALL from craigslist. It's the most efficient system available. 100k BTU for 220 watts.

    Do you recommend parallel piping the collectors? I have 4 collectors flat plate piped all parallel, and when the pump turns on the temp just rapidly drops I am using a 009 stainless and I think it's a little too much velocity. It's the same weather I drainback or have it filled.
    My sensor is inside the panel but on the header pipe.
    Also my 009 stainless pump is a "cartridge" circ and I was wondering if I could swap like a 007 cartridge in because it definitely works better with a slightly lower flow rate.

      Update: I have a feature on my pump control so that when the sensor hits X **F to prevent overheating. Now the pump runs more constantly and I'm getting a good 190* * to my 50gal thermal Cell. Ideally I'll eventually upgrade maybe to a bigger tank. Or add one hmmm... now I'll drain it back to the drainback point and see how it performs. What I've found with solar is that I have to experiment to see what works best and the simpler the better. I used thermal traps instead of check valves.
