To all,

Here is a video that my daughter-in-law made for me. On the 36 Vacuum tube Solar Water Heater. How to put it together. She is very talented.

My son Keith,  built my web site too.

They are good kids. Take a look and let me know what you think?

 Greg, this is pretty interesting, I watched the video and looked at the site and yes they did a good job. Would really like to see what results you have in colder temps, if we would use the style with the tank and exchanger on top then the lines from the boiler would be insulated and run from a constant running separate pump (just like another heating loop off the boiler), correct? I could see this working in the shoulder seasons and summer for DHW use but have a hard time thinking there would be much benefit during the middle of a northern WI winter. Seems hard to believe it can work down to -30 and be freeze proof. Sounds like you are just getting this going, best of luck to you, its a great concept, we will keep our eyes on your progress.

ITO,

I've tried to reply to this 4 times. Here goes again. It is kind of hard to believe until you see it yourself.

I put a vacuum tube against a table and filled with water. Started out about 60 degree water. In 5 or 6 hours the water temp. in the tube was almost 225 degrees. Water boiling out the end of the tube. The outside of the tube was cool to touch with the inside 225 degrees.

Could not get pics to send.

Greg - what's in the vacuum tube, water, glycol, air, etc...?  Like ITO, it's difficult for me to wrap my head around something that can produce heat in minus temperatures.  This technology is new to me so forgive for me for my ignorance and skepticism.  Roger

Roger,

Its a glass tube that you fill with water.

Its glass inside and out. Its vacuum sealed and has a black solar collecting material first, then a layer of aluminum and then a layer of copper.

Roger,

Another picture!

Greg, thanks for the pics and taking time to answer my concerns.  The pictures are rather convincing.  How long did it take for the water temp to get that high?  I imagine it didn't take too long.  Roger

how do they stand up to ummm  lets say  golf ball sized hail ??

[Jwood]

Now there's a good question farmboy!

[Sprinter]

What is the manufacturer and or any links to their data. Might help others understand a bit better.  The construction and operation. It seems that these would easily keep a hundred gal of DHW on tap from March thru October , and a good solar circulator would monitor and maintain peak output as the weather changes.

Good post Sprinter

Roger,
I started it at 9:00 am and checked at 4:00 pm, the temp. was already at 225 and the water had steamed off to 6 or 8 inches below the top of the tube. The time was under 7 hours, don't know exact.

Farmboy,
I'm told they will withstand a gulf ball at 50 miles an hour? I not going to test that. LOL

Sprinter,
I'm sure they are made in China, the bolts are metric is one clue. If you google  vacuum solar water heater. There is a lot of info. out there. There is also several ways and what kind of material they are made of.

Hope this helps.

To all,

Maybe this will help you all to understand better.
