Nice job I am building one too hope to have the video up in tree or four weeks

great video. I love the music. I am building a simple heater from plastic bottles and soda cans. I made a video to show what I am doing. People need to start believe that the sun provides enough energy for a year in one hour, for the whole planet !!!

I’m impressed! That is quite a system. Does it matter where you measure the temp on the collectors? I’m guessing the evac tube manifold is the smartest spot? Also, you didn’t cover the heat exchanger aspect. Thanks for sharing!! Solar thermal is gaining popularity around here …

Thank you very much for the video.my system is very primitive compared to yours.I do have a temperature control unit I just need the sensor for the panels.I will research a better pump so I can run it off my solar.thanks for the great advice.

@Fearlessthinker Thanks, F. Yes, the evac tube manifold has a 1/4″ copper tube hole for a sensor. I put the diode heat sensor in there because I think the tubes heat up first, especially in cloudy conditions. Also, I was concentrating on the pumping efficiency issues because I came from watching michael970′s drain back system and I had similar pumping issues at first. The subject is very much related to running an elevator with or without a counter-weight. I had trouble shortening the video. lol

@michael970 You’re welcome. I enjoy your videos, too.

@ch14aphilipp then it wouldnt have concentrated at the bottom

@svtcontour I think that’s exactly what Dan’s trying to demonstrate. The warmer water rises into the flask, while the colder water enters the tank. What’s causing it is the difference in temperature. Density is exactly the function of temperature, since the material in both containers are the same. Ice has a larger volume than water because it forms crystals. Cold water is still denser than warm water, until it’s actually crystalized into ice.

@Nomoreidsleft I guess it can be looked at it this way. I guess I was looking at density instead of heat but like you said, they are in this case linked.

Cold stuff is more dense because the particles are closer to each other

like ice 0_0
