#8. One Year Review.

As it turned out, there was practically no freon left in thermal siphons. Most likely, the majority of it leaked through the joints, however, I have a strong suspicions that certain amount of it escaped through the walls of a metal-plastic pipe.

This is an interesting issue, I’ll have to think about it more.

• Almost empty.
• Also empty.
• Some slight excess pressure here.
• But obviously, not all freon is there.
• This one is empty.
• This one is empty too.
• Empty.
• It’s empty.
• Nothing here.
• This one probably has the most freon left.
• But not a lot…
• When there is a lot of pressure.
• When there is a lot of freon, it almost flies out from there.
• That’s all.
• Oh, this one has the most freon left in it.
• So that’s just how this goes.
• G’day, fellas!
• You just saw the state of thermal siphons one year after the start of this project.
• There is practically no freon left in thermal siphons.
• The residual quantities that you saw are not even 1/10 of what was filled earlier.
• Probably, it depends on the quality of joints in this or that thermal siphon.
• Most likely, the majority of it leaked through the joints.
• And a certain amount,
• I have reasonable suspicions of this,
• Escaped through the walls of a metal-plastic pipe.
• If you remember, earlier I made a video in which I showed how a thermal siphon works.
• I used a transparent pipe there.
• So, from that pipe, the freon leaked completely after about 2 weeks.
• And it definitely leaked through the walls of the pipe because I crimped it.
• The joints were completely sealed.
• But at the same time, the freon just flew away.
• The pipe was transparent there, made of a different material than a metal-plastic one.
• Therefore, the freon escaped a lot faster.
• Generally speaking, the freon does not escape from a metal-plastic pipe very quickly.
• So if you are ready to fill your pipes every year with freon.
• Keeping in mind that you don’t really need too much of it.
• Then you can use this method.
• But after the 2-3rd refueling, you will get tired of it.
• I assure you.
• One possible solution here is to use a copper pipe …
• pure copper.
• But It will be quite expensive.
• And, probably, it will almost be comparable to the cost of using DX heat pumps.
• Well, it’s definitely something to think about.
• And in addition, the practice has shown that the total heat power is less about 2 - 3 times.
• than from a pipe like this.
• Therefore, naturally, the total length of these pipes must be about 2 - 3 times more.
• My house would need around 400 - 500 meters of it.
• 70 meters which are already there, are clearly not enough.
• Well, since we already mentioned it, this is a little teaser of my next video, so don’t forget to subscribe!
• This one should be really interesting, so stick around.
• The issue with thermal siphons has not been completely closed.
• I’m still thinking about it.
• What will happen?
• If I think of something, you’ll be the first to see it!
• All right, hope to see you in future videos! Good luck!
