This is the second episode in a series of videos on building the geothermal greenhouse. This is the one where it all happens! 🙂

Good thing for your dad, you barely did anything lol
😁👌🖖✌👍😎
Maybe I'm missing something but don't you worry about radon gas creeping in through the soil and the tubes picking it up?
Why don't you use metal pipes under the ground for better heat conductivity?
Awesome video. So, is it better to dig deeper and use more rock as a heat sink?
Why would you use perforated pipe?
God bless you all. The Gospel is 1Corinthians 15:1-4, Ephesian 1:13, 2:8-9, Roman 3:23-26. Without blood there is no life and without Jesus BLOOD no eternal life.🕊️
Stuff with more mass holds temperature better, water has more mass than air so moist dirt seems like it will be more temperature stable than dry dirt because it is more mass. But it won't matter anyway either way because if you dug down below your freeze line in your area, then the earth itself keeps its temperature stable down there regardless moist or dry. That is the whole purpose of using geothermo style, taking advantage of the stable temperature under the freeze line, summer or winter. But i figure you must be talking about temperature transmission, or temperature conduction between the earth and the pipes, because i know you must know what you are doing. And i agree if that is what you meant, to get better temperature transmission from the earth to your pipes you used large gravel with big air gaps so in essence you are extending your pipes into like a tiny vein system which can extract more temperature. Genius thinking.
I didn't catch the reason you used perforated pipes unless my figuring was right above, maybe i watch again later i missed some stuff.
good work , gravel does not retain heat better than clay , having air pockets makes it worse as it insulates you want dirt to stick to your pipes to conduct good .
also heat renetion does not stay for a whole season yes you can retain daytime heat for release at night but not summer heat for release at winter
HI,I would like to know the pipe details like type of pipe used,its diameter,details the insulation blocks you are using in the sides and also the black sheet which you are using in between the layers of pipes and soil.
Thanks
Did it work well for you?
I may have missed it, but what size pipe are you using here?
Radon concerns with that crushed aggregate
1970s Vermont all over again
hey
great job u did
now tell me the resultant cool air
or a data /
I mean outside temp. and inside temp
is 40degree Celcius outside
then how much inside will be.
its just example
u tell me your result.
Any update? Is it working?
Hi great video!
What country are you in?
Did you build the greenhouse? DId it work?
Great video and hope you post an update on how its doing now. Any problems with water entering inside the tubing? Also, What kind of temperature probe did you use for the underground ?
Happy you were able to do this. A brighter future 😉
You have beautiful eyes.
cubic feet / 10 = linear meters of pipe needed? Why use feet and meters for this? What about cubic meters / 10 = linear meters?
Christopher, Great video thanks for explaining step by step. , this has helped very much. Thanks . Good luck with the Green house.
Thanks for your video. And I wish you success. I assume by now you are up and operating. I am concerned about mold growth in the buried ducting. How would mold not grow in the buried ducting? You are not going to any usable air volume through 300 linear feet of 6" corrugated plastic pipe, By now you may realize you should have installed 14 to 18-inch headers. I have yet to build, but my scheme involves supply and return wells and heat exchangers. Take Care. Mid -Atlantic US.
Covering pipes with drainage material is very stupid idea man, this way there is much air around the pipes, and the air is good termoisolator, so the heat exchange is lower. The best you could do is to make a bed of clay under the pipe to hold water and make the soil around pipes denser this way you will improve heat exchnge between the air in pipes in the soil.
❤️🇺🇸YOUR DAD RUNS THAT EXCAVATOR LIKE ITS PART OF HIM❤️🇺🇸 can’t wait to watch part three! My difficulty here is you dig down 4 feet and you have flat ledge at 4 feet and I think I’m going to dig down to it and put a temperature probe there and watch it this winter because I think the ledge itself will hold or deliver more heat and the rock?
I wonder if you clean off the ledge in a similar area put the tubing down and anchor it and pour a concrete slab directly on top of the ledge and your solid piping, would that then become a much better heat sink😳. Hmmmmmm I wonder???
vertical hole diging is cheaper!
You should check out the Thermal Greenhouse build on HowToFarmAndGarden.com. They used 6" perforated pipe with large rock around it. A bit different approach but the results are amazing.
This is not the way to do it. Check out Retire growing oranges in Nebraska. He knows what he is doing.
Thanks for doing this Step by Step.😊
This is so interesting and fun to watch. I love your “can give it a try” and “just experimenting” attitudes, but know you must have put a few hours into researching as well! I look forward to seeing your results. May the Force be with you, too! You must sometimes have some sore muscles!
Very interested to hear how you got on!
Nice vid – how’s it going with the geo thermal greenhouse? Thanks 🙂
What is the reason to use perforated pipes?
please do a update on this video. I like to see how you set up the fans. also whats the ground temp.. I want to try somthing like this myself.
thank you..
Will those pipes hold the weight of that soil??
this video is perfect for my situation
As pointed out by others, each run should be supplied with air through a header – you will not be able to pump enough air through one long run. Sadly, you see the same problem with the solar thermal people where they use one long run of copper tubing. You have to keep the air and/or water velocities relatively low to avoid large pressure drops which in tern limit the efficiency of the fans or pumps.
How did it go? Good ,Bad etc.?
You are copying the wrong system. That isn't even proven and very expensive. Use this system, https://www.youtube.com/watch?v=ZD_3_gsgsnk ! It is proven and only expense is digging 8" trench for 75' of pipe.
i bet loose gravel has a horrible thermal conductivity…
и в каких регионах это ?если север,то понятно будет эффект а стоит ли городить огород с такими сверлениями в Крыму?
Just curious, why did you not run your temp communication before you started to backfill?
do you also have some guidelines for length and diameter of pipe when they are filled with water? i live in dubai and aim to col down the pool water by 5-10 degrees by running pipes under ground.
How is your geothermal heating and cooling system working? I put one in almost the same as you. Mine filled with water and I can't get anything all the way through the tubes to pump it out. You have that problem at all?
