[@swiftarrow9]

Thank you for sharing, especially for your ingenious method of hole boring!!! I really appreciate your showing that because it's so low-cost and so creative; I have gotten in the rut of thinking I "must have special equipment" and your video brings me back to reality. Because you asked (and ONLY because you asked) , a couple of thoughts from a renewable energy engineer: 1. If (WHEN) I do this I'll put antifreeze in the lines; yes it will be expensive, and for 99% of the time unnecessary, but it will be an additional factor of safety. I'll also dig my horizontal lines lower (my frost depth in a good winter is four feet). 2. I hope the turnabout fittings you have at the bottom of your wells are rated for really high pressures; otherwise they might get damaged over time. I would probably improve on your method by wrapping the ends in something to protect against gravel intrusion. 3. It looks to me like you sunk way more than enough wells. I would be curious to know the results of a load test (if you are cooling in the summer, how much heat can the ground absorb before return water starts to get warmer, and vice versa for winter?) 4. Also out of curiosity, when I do this I'll try to find budget to sink a thermocouple down some of the wells to measure resource temperature.

[@Dususdo]

I love the way you drilled the holes. When piping I would have done a common flow and return header with individual branches for each drop, easier to vent. Maybe filled with glycol too. Great vid

[@themanwithabilities5908]

colder climates will require a deeper trench for your horizontal run. example, Minneapolis permafrost depth is 3.5', so plumbing water pipes are set at around 6' deep or lower. meaning, the ground is ice for around 3.5', and will cause problems with water pipes used for geothermal transference. nice diy.

[@larryshea8595]

This system is charged with 70% propylene glycol, a heat transfer fluid with anti corrosion properties. Freeze protection to 30 below. (Do not use ethylene glycol. That is car motor antifreeze. It can contaminate the aquifer.) Watch, "geothermal diy #2

[@lancegoebel]

Great idea. Can you do a short video using an infrared thermometer to show the incoming and out going temp of the water, during a hot day, and a cold day. and give the outside temp and temp inside the room. And maybe put a metal object in front of the fan to get a good idea of how cold (or hot) the temp of the air coming off of the fan is. also can you tell us how much water per minute is circulating, and how much kilowatt hours are being used.

[@markterhune9228]

Larry, you could lay some solid insulation over your wells and links to not lose a few degrees of ground temperature in the circuit. And even wrapping those pipes with insulation before covering them with foam board or other hard insulation material. I built a geothermal house did the complete install of pipe in a ground-loop system, built my own riser board to mount the pump, valves, to a Waterfurnace heat-pump. I heated and cooled the 3500 sq ft for $150-175 per month. It was a super insulated house with foot thick walls and 1 foot of attic blown insulation.

[@JohnGuest45]

I agree insulate the upper tubes because heat will be lost to the cold ground in winter so less heat will make it back. In summer the ground will be heated by the sun which will reduce cooling performance. To my mind 60ft2 of tube surface area isnt a lot for heat exchange.

[@tbix1963]

Good video, looked like a fun project. Reminded me of a rig my grandfather had in his home. Probably 40 years back I was in the basement of my grandparents house with my uncle probably in his 50’s and he pointed to a copper pipe tee with two 1/2” pipes attached thru reducers to it and a 1-1/2” pipe coming out the third going into the ground. Questioned me do you know what that is, follow the pipes and try to figure it out? The T was oriented so the angle was off to the side, went into a reducer then a elbow and went up parallel to the other 1/2” pipe coming out the top thru a reducer into the house. The third 1-1/2” pipe went into the ground. I traced the pipes out, the side pipe was connected to the water main and the second went to the cold water tap in the bathroom. I was still clueless. He said you ever notice the water in the bathroom is always colder than the other faucets in the house. He said back when he was young and they moved into the city from the country his dad was upset whenever he got up in the middle of the night and wanted a drink of water be cause the city water was so warm compared to the well water he would have back at the farm before they moved. The third thicker pipe was a pipe inside a pipe and went 60’ into the ground to cool the city water. How many years back was it when they put that in, no clue, but the day I discovered the term geothermal for cooling I knew exactly what they were talking about, no convincing required.

[@davidnormandin5428]

Putting it in the greenhouse is a great use for GEO. I put a sand floor in my greenhouse and electric ground wire system fresh tomatoes in December but the cost of electric heat made it impactable. I know there is water on my place there use to be a well covered now with a BBQ a rock ledge may be my only problem if the spring is running under or voer the ledge.

[@angellestat2730]

You deserve more views, you did with 1000 usd the same than others do with 15000 usd and using more energy as well.

[@DominicNSX]

In combination with a heat pump you could get three times more heat.

[@user-sr7fo5fe6x]

What does that mean..? (I'm a novice, trying to learn about GeoThermal heating).

[@Aerogrow]

@@user-sr7fo5fe6x basically like a fridge; compressor and refrigerant of some type; heat exchange to ground loop. What he doesn't mention is the cost just went from 2-3k to 10-20k. For an outdoor greenhouse; this simple system is perfect.

[@stevelamperta865]

Unless I'm missing something here , why would you need a pressure tank for a system that wont ever have high temp that would cause expansion ?? Its a complete waist of a pressure tank that will never see any pressure ! Unless your planning on using another source of heat on this system.

[@terrafirma9328]

You need pressure to push water from that deep.

[@sallorta2006]

Amazing! I am moving to NC and want to build a greenhouse thanks for answering the A/C portion in the green house! Im going to add solar and batteries with an A/C inverter to run the pump and fan! Thank you very much!

[@user-sr7fo5fe6x]

Watched an 'off grid program' of a guy in Alaska ('Homestead Help' or something like that) and this guy had set up a greenhouse 'in Alaska' a 20' high glass, double insulated blah blah' and was growing Avocado trees inside'. He had it attached to a GeoThermal circuit and said 'my heating costs for this green house come from the heating I have inside' (the house) ' and geothermal." "Can't allow any frost in here or its 'all dead' (gesturing his trees and edible plants)." I was blown away. A greenhouse in Alaska usable ALL WINTER', even during 'dark days'. Wonder if they do that sort of thing in Russia?

[@MetalHbreaker]

Now if you have central air in your house. You could install a evap coil and run this water throw it. Then use a relay and the exsting thermostat in your home to control temp by controlling the pump and fan. Also there's already an existing way to collect condensation in a air handler or evaporator case. Plus the added benefit of filtering the air.

[@pilotrserra]

Nice job Larry. You gave me a great idea about drilling the vertical loops

[@brettmoore3194]

That's great for cooling but a black3/4 line in a spiral out in the sun .insulated. Would be the hot line just would have to put a few ball valves to switch from heating to cooling. Thanks for the idea

[@BanderAlraqqas]

Hello Larry thank you for sharing the video. I am building a greenhouse for my hydroponic garden. Its very very hot here in Kuwait, and I want to use 2 cooling systems: Geothermal and water cooled air-conditioner. I buried my water hose 4 meters below surface. Because the sand is very dry in the summer. I laid plastic sheet under pipes to help keep moisture. In addition to that, I connected a drain pipe to about 3 meters down when I drain my water/solution tank so that I keep some moisture around the underground pipes to help in heat exchange. I am still curious about the delta T, temperature difference. I will add a water thermometer for water in and out of the system.

[@robertling9872]

Thank you for sharing. Smart idea.

[@peterburris4665]

[@SuperEdrix]

I am a electrical engineering student in the netherlands. We use alot of the geothermal effects of the earth. I really liked your video. I searched specific for DIY cause I want to make this one day. In short. You could also make the system to drive a generator and produce electricity. I really would love that. good luck

[@SolarTechFL]

Yeah maybe if your near a volcanic vent lol to use a generator you need steam to make steam you need lots of heat probably start at 400* f.

[@schade12]

But produce electricity need 2 wells of 1000 metters to make steam it's costing

[@allenshattuck9881]

Not sure this system would work were as the temp is only 55 to run a generator. it's already using electricy for the pumps. it would cause a lot of friction loss to on incorporate sum type of electric generator.

[@johnwyman6331]

You don't have to have steam in order to generate electricity. A stirling engine only uses a heat differential to create mechanical energy from a heat source and a cold (less heat) source.

great job man! if i did this at my place i would need a rock drill attached to one of those fence post augur machines 😅 considering how expensive commercial setups cost, youve saved a mint

[@barrellcooper5343]

Some thoughts - First congratulations this seems very cool for a DIY project. These are not meant to be critical just observations: You may want to use it to "Air condition" the garage during the summer. Not sure what this will cost to run the system. But it will do positive things assuming you want to cool the garage. The other thing running it during the summer will do. It will be warming the ground up so that you can pull more heat back out in the winter. One problem all closed loop geothermal systems suffer from is that as the season continues the ground gets hotter or colder. So "pre-heating" in the summer will help with the winter. If the system is large enough this is more of a theoretical concern than one that is practical. But the ground will cool down the longer you run the system in the winter time. The other observation I have is piping layout. You could do it with a lot fewer elbows. Elbows cause pressure drop and reduce flow or require more power from the pump to produce the same flow, and more joints means more leak points. If the flow is slow enough the pressure drop is not much of an issue. But I saw a lot of opportunities to make the piping more direct and cut out quite a few elbows. IDK if the pump needed to be horizontal, but you could have put it in the down leg instead of crossing back to the other side, or even just kept it in the same horizontal run as the tank and air bleeder.

[@earbjr4715]

Looks logical. We have slate ground. A bit different, but the logic is good.

[@hootche1]

Larry, 1. you should have filled the boreholes up with BENTONITE CLAY, to get better thermal contact. 2. did you put antifreeze in the system, this greatly improves the thermal transfer of heat.

[@randymeyer6482]

...as long as the bentonite stays moist...if it dries out it will pull away from the loop, creating an air gap...just something to think about...

[@terrafirma9328]

Free dirt is cheaper. Dirt cheap🤣

[@LikeASimpleLife]

Have to say it is well thought out.... and you have left the system open to adding future mods so you are covered. The only thing I can think of is a variable-speed motor. It would cost out front but pay off in the long run Also depends on the future mods.. But for a DYI you did great...

[@brucegraham2128]

[@mp-xt2rg]

The info on digging the vertical loops is good. The end system will have little effect heating or cooling. You need to put a heatpump in the system.

[@Jamaicandoctor]

Wow. I dont know anything about this but i am definitely trying it

[@larryshea8595]

Stuart, çheck out "Water Drill Bit Repair". It will show how to make the water drill for your well holes. Remember, this drill does not work well in stone, rock or gravel unless your water flow volume and rate can bring up stone. My ground is sod on top followed by 10 inches of yellow sand and then hard clay going down as far as I have ever drilled. My deepest hole was 25 feet.

[@piccirilloxx]

[@DJSincereTV]

I dont know why this wouldnt work on a large scale with an air return and a decent sized cfm fan. In fact a solar panel on the circulation pump. And some simple duct work for a return that pushes the air over the coil and boom. You need only a drain for the condensation and I feel like you can heat and cool as big a space as you want

[@thatdude8247]

[@44xxggaaj]

Great simple design ! I know it would cost more but using copper instead of plastic would transfer temperature more efficiently and last longer underground than plastic .

[@stivi739]

The cost would kill it

[@lab_rabbit]

Copper certainly has better thermal conduction, but the added cost isn't worth it. Rather than significantly increasing costs and complexity by using copper, you could just drill a few.more wells. you'd also have to solder every fitting instead of easy to use hose clamps. each run of pipe would have to be thought out so the next joint could be made as opposed to just moving the flexible plastic where it needed to go. Last, I don't think copper would deal with the ground settling and heaving from the frost as well as a flexible solution will. So lots of drawbacks for better thermal conductivity that can be compensated for by adding a few more wells.

[@tomschwartz4853]

Once you put a heat pump on that circuit, it can be used for AC as well as heat. You will most likely need to have a heat exchanger and put anti freeze in the circuit. Note in northern locations you need to go 5 feet down with your trenches. The pros use poly fusion because of the glycol. They also fill those holes with concrete. Just saying I have worked on these systems as a plumber and steamfitter.

[@kurtspann442]

[@robertlaird6746]

I'm planning on building a Climate Battery underneath a greenhouse I'm designing right now and that made me think about doing that for a raised foundation home if I were to use an ICF foundation and SIP's for the exterior walls and roof. I'm also interested in doing a system like yours for hydronic heat loops underneath the hard wood flooring to radiate the heat. I've never seen a system like yours but it's worthy of consideration to think about. I would think that combining at least two systems together would work supper well and might increase the temperature in the winter. My thought would be to install your system as a radiant heat loop system in concrete and have the tubes attached to rebar inside of that concrete so that it helps transfers the heat to have better heat radiation coming from the concrete inside a greenhouse. Put that block of concrete or wall of concrete on the back wall of the greenhouse or even the floor but also connect it to a solar system to increase the output and thus be able to heat the structure to whatever temperature you desire for free besides the cost of the supplies and labor. I'd have to think about this a little bit more but I can imagine doing this same thing in a home. I'm a carpenter and build homes from the ground up only using my own hands and without any hired labor except on concrete days.

[@philxcskier]

Gotta say, the way you dug your holes is really smart! Sometimes the simplest solution is the best. Really cool. Like you mentioned, you could add a ground source heat pump to this loop and depending on your insulation and the climate you live in, you could have a heated garage, or heat a hot water tank.. or all of it as well as cooling for the greenhouse! The bladder tank is a nice touch, it will keep your pressure consistent, but as an added benefit you run a lot less risk rupturing your lines with a temperature change of your fluid.

[@naveedutp1]

hi larry, its great, i have few question if you could answer, first your design is way simpler which is great for people like us, i am interested in cooling only, (not heating), now 1. how deep you put tubes inside ground 2. what was your ambient temperature ? 3. what is your room temperature 4. what is outlet temperature of your water coming circulated via ground pipes ? and what was your room temperature becomes after system was running, appreciate your support here

Great idea. We have been discussing this kind of thing since the 1970s. Virtually no environmental impact. Initial investment very reasonable.

This will probably work for what I need and forget the different Freon expense.. Had central A/C until it got a leak, here in Wis. are ground temp 8 ft down is about 55-60 degrees, so I thought I use the geothermal concept for doing cooling on a 1500 sq ft home, trenches would be 8 ft deep, run a continuous close loop system (2000 ft long) and a couple of pumps inside, to pump in and pump out, with a water to air heat exchanger on top of the furnace. When thermostat set to cool, turns the furnace fan on along with the pumps, cooling the house hopefully down to 70 degrees, I do like this system and will look into it, anyone out there with ideas, I appreciate them.

The connection is a "U" coupling. The fluid goes down then comes up. Each tied together for a continuous loop.

[@rainsz1]

Hi Katie - The connection is a "U" coupling. The fluid goes down one then up tying the ten pairs together for a continuous circuit, each conditioning the fluid for use.

This just went on the list titled " What would You do with an extra $1000/mo? " great job man! im curious as to what you would do different if anything after having used the system and what performance tweeks you would make if you did it again.

[@lazarus1313]

Good job , well done . Money saved and good indoor climate , armchair experts didnt understand your gain , but you said it : colder than shit , thats good enough

[@Stuart68505]

You might want to use some type of anti freeze solution as insurance against small sections that may get exposed by mistake to freezing temperatures.

[@larryshea8595]

At the end of the video their was an opportunity to view the video, "GeoThermal DIY #2" which demonstrates the insertion of the Propolene Glycol antifreeze into the system. You can view the video here, kzbin.info/www/bejne/ppetgop6m55obqc Glad you enoyed the video.

You made it so easy I Know is lot work but the system .. Thanksss

[@joerathbun5225]

I think you did an awesome job...

[@mmeyer9317]

Hi Larry, I’m extremely impressed with your ingenuity.. truth is brother.. I need this bad LOL I’m a military guy here in Tennessee, (101st AB Div) I have a remote piece of property, and I’m building my own hybrid cabin. I’ve done all the work myself. so very close to being Completely off grid... but I certainly could use some expertise or suggestions on how to complete a project like this, do you have a materials list by any chance That I could get..? Thank you!

[@douglaswindsor120]

I was hoping to see a diy heat pump using that warer

[@imdo301]

Looks perfect

[@bretgreen5314]

Well done; thank you

[@MrAgatto2]

Damm that is the cleanest shop i have every seen...... is water flow on demand from the stat only ? Also do you find the small ex tank sufficient , i was thinking a larger tank would be nice but may act as a thermal sink

[@mosfet500]

Thank you. I think it depends where you live. I live in the Catskill Mountains of NY and our ground is hardpan with lots of rocks so going down 20 feet might not be possible so I would have to find another way to dig down that deep. I'm wondering if you're getting some loss with the upside tube being close or in contact with the return tube, maybe insulating the tube for the last 4 or 5 feet might yield higher temps. A lot depends on your location and soil but at 20 feet you should have pretty stable temps. I measured the temp from my 175' deep water well, I'm getting about 54° to 56°F by the way. Interesting thinking, very creative, thanks again.

[@iwantosavemoney]

I think it will work but for how long is the question a up date would be nice great build sir.

[@bassmouter4694]

Great, simpel design. Congratulstions!

[@user-sr7fo5fe6x]

Excellent DIY design. No 'contractors' necessary. Would love to see more of the howto on the drilling. Perhaps he could have gone deeper and buried the 'hosing loop arch' deeper down to avoid frost and get a more consistent temperature. Love to know what region he lived in and 'base temperature' of the soil.

[@bassmouter4694]

I noticed recently at Leiden, Why those contractors putted down A few hundred meters 2 inch black plastic pipes.. geo thermal heating ! Because of the clay did they use drilling machines, and they digged A large scale of pipelines at least one meter deep in the ground. Thanks A lot, to see this simple design! Have A merry Christmast, and A happy New year.

[@bassmouter4694]

@@user-sr7fo5fe6x , however use Google by checking what this man promissed: Normal at ten meter deep, water temperature is only 12 degrees Celsius. In the Netherlands have we to dig 100 meter, before the temperatures teaches 55 degrees Celsius. So, our men must have known, to have builded his house above A warmwater well... His systhem can help prevent agains frost, and iT might help to cool the house in the summer till 12 degrees Celsius. But by 20 feet in No way till A warm house.

[@bubberD]

Genius! so glad i found your video

[@halohms]

Not deep enough, too close together and in total, not enough pipe. If it was 0F outside and you ran this setup continuously with your greenhouse on top of the field, you will eventually lower the ground temperature to well below its before steady state temperature. I suspect no follow up because it didn’t work as intended because the ground isn’t a perfect heat sink for that small pipe field.

[@terrafirma9328]

Wrong, wrong, and wrong.

[@derekrunyan983]

Looks awesome would love to see some video evidence of efficientcy temp of radiator vs air temp before/after on/off Few hours or however long you like I mean it's a lot to install

[@craigsmith248]

Nice work, thanks for the info.

[@somethingnewtotry5360]

Can you do a follow up and if you’d do anything different please?

[@nappingpup105]

Very nice.

[@mrtough5394]

In the winter cover the ground with a thermal blanket

[@terrafirma9328]

Y?

[@pankajdhawan2130]

Great job

[@AndrewStAmand-pl4bf]

At a quick glance, i noticed no one commented on the staging and routing of the geothermal system. it is common knowledge that an electric pump generates it's own heat and is cooled by the water it is pumping. the proper order for this type of system should route from the field through the radiator first, then through the bladder tank and finally through the pump and fed back to the field after having lost most if not all of the heat. hot water through a pump will cause it to fail prematurely. plus you want to use the water for heating at it's hottest available, the less time the water has to cool before going through the radiator, the more efficient the system will be.

[@markc.3021]

Pumps used on hot water systems using a boiler are designed to function efficiently with hot water and not fail plus remember this water is only 55-60 degrees anyways

[@timpersonett2404]

Nice Lary thank you !!

[@dougbarrett7803]

I would also like to hear how it's working out

[@user-sr7fo5fe6x]

Excellent DIY setup. Can't believe you did nearly all that yourself. I have concerns about the depth of the lines outside. Do you get frost in your area? What is the likelihood that frost will affect your circuit during winter?

[@kevinlewis9151]

I think you could have gone down 25 feet or so for the drain and then as deep as you can get with a mini jetter set up and then used all the surrounding ground well water depending on how you filtered it and maybe even routed it through your home or water heater during the winter for heat.

[@mikedee6915]

nice job thanks.

[@barrettward9911]

I like your system and the simplicity of it. I'd like to incorporate a ram pump into a system like this. I think ram pumps have a great potential. My thought is to just have a long loop that continually runs with few things to maintain or energize. I would appreciate your thoughts anyone.

[@JasonLee-fc2ot]

You would need a stream of water (gravity) for ram pump. Not sure if it would work in a closed loop like this.

[@cescocesco1973]

Very Nice! Why did you decide on 10 wells? Why not 20 or 5? I love the idea but would like to know more about the thermal capacity of the ground. Can I "heat" the ground losing efficiency but gaining planting time in a greenhouse, can a system be put in more linear and help keep my grapevine roots warm all winter... LOL, all rhetorical....I love the idea!! Nice job!!

[@6969smurfy]

I have studied Geo for cooling process water in the summer & heating in the winter. I came up with 600ft under frost line can equal 1 ton off chilling/heating

[@SuperEdrix]

BTW mayby you could somehow make the hot water into steam and power a small turbine that powers a generator. Thinking small ofcourse not like reall geothermal power plant size but small. I don't know if there are such of things. but it would be nice

[@howtoguro]

You'd need to be in iceland or somewhere like a plate boundary. In the middle of a continental it's not hot enough for steam any reasonable depth in any reasonable place. It could work at old faithful, but... it's not really accessible.

[@allenshattuck9881]

I heard or a guy working with freon to turn a steam turbine because freon has a lower boiling temp. Could do some research to investigate.

[@craftytimestation2540]

Only about 20% of the United States is suitable for geothermal power production that's more of an opinion really it's quite expensive to go down as far as you have to go there's a lot better sourcesOr I think eventually getting solar and geothermal energy are only real options
