One thought is the warmer it is, the closer you get to the 1:5 efficiency's. Point is if the ground is a lot warmer, heat pump may be as efficient as 1/5 the electricity and will only turn on if needed meaning if the ground is hot enough, it uses 0 electricity, if you set it up and design it that way. It gets closer to energy storage with the capability to heat for really cold days as well. It can even cool with dual imput setups.

Lastly, the volumetric capacity of water is crazy higher than sand. If you are already going to insulate, just build a pond and increase the heat capacity 5-10 fold. As long as you don't heat it beyond 90-95c, it's perfectly safe.

How about a dual system? Bury the pex about 4 - 5' down under the green house connected to the solar hot water heaters to warm the soil like a radiant heated floor in a house. Install a second layer above it to capture the heat in winter. Then bury a field of pipes outside the green house, to use for cooling. In the summer the water heats the soil while the other field cools the GH. when winter arrives, the cooling system is shut down except on warm days, and the upper layer of pipes extract heat from the earth battery?

I am in the Westport, Ontario, Canada area. I started designing a lean-to greenhouse on the end of my house. It will be an, 18' long, 16' wide and about 14' high, arch. East west orientation. I won't get into the details of the build itself, however, the heating system is what I wish to discuss. But first some land details. I call my 2 acres, Bedrock Flats. Most everywhere here the max you can dig down is anywhere from 1" to 8" before you hit bedrock, in some areas it is on the surface. However, my house has a crawl space of about 40", the foundation walls sit on the bedrock, which brings the main level up to about 4' above bedrock. All the ground around the house is back-filled up close to the main level. So where I am putting the greenhouse has about 36" of back-fill. My thoughts are to dig out the entire area, where greenhouse will sit, down to the bedrock. Place a cinder block wall, anchored to the bedrock, insulated with 2" rigid insulation on both sides and flaked out around the three exterior edges with 4' x 8' of 2 " rigid sheets (to help prevent frost from getting into the area). Here is where it gets into the heating system. With this small of an area, will laying 1/2 pex water lines, coiled as you suggest in one of your videos, back-filled to grade, and run up to a circulating pump to push heated water in summer down into the earth battery and reversed in winter. You can see where I am going with this. The question I have is - will this relatively small area, foot print, be enough to gather heat in summer and store for winter. I want to add something here that I find interesting. I have small 16 x 24' shop which sits about 30' from my house. I ran a water line out to it which sits on the bedrock in about 8" of soil, insulated and heat traced. However, I find that the heat trace very seldom comes on. I am thinking that it has something to do with the bedrock. It goes down quite deep, 20 to 40 feet in places, I know because of the well drilling in the area. Is this in itself some kind of natural earth battery? Will this help with my greenhouse heating system. Will the system even work at all? Thanks Mike

Forget about the foamcrete or any crete for the "Ground Battery" dig your battery hole 8-10 feet deep put down perimeter of IFC blocks 2 high add to the floor 4-6inches of Expanded Polystyrene (EPS) foam board. Now it gets interesting with this part. We are going pack dirt into those ICF blocks use of rebar is optional. Line the inside of that battery with a pool/pond liner or some strong plastic maybe the fibered canvas stuff for greenhouses is like 10mil with fiber. This plastic does a few things for us 1 unlike when doing under slab insulation we are not worried about it filling with water later we would prefer to have it fill with water for better thermal exchange. But we dont want that EPS to float up so the plastic will hold it down as we add mass. Now lets add 1-2 feet of fill and tamp/pack it down this should be done in 6inch lifts but we dont want to hurt that foam so do a 1 foot lift then another foot. Next fill the walls up with the dirt packing to the frost line and fill the wall in lifts of 6 inches and tamping it the best you can. Now back to the battery at this point we are still at a depth of 5-7feet and we lay the entire floor with our hot line from solar the loop over loop method or concentric method using less total length of pipe is your choice. Those long metal staples for holding shade cloth can be your friends to help hold the pipe in place. Now we add another foot to the battery and also the outside of the wall up to the point the inside is filled again limit the range of lifts and compact the soil we dont want anything shifting the wall around to much. Now we lay our pump side line 1 foot above the hot line. At this point we can get our liner put down the outside of wall and do another foot lift. We will then continue until the battery is full to the frost line leaving outside of the wall 1 foot shorter and we will cap this battery with another layer of high quality plastic and down the outside of wall adding the last foot around the wall to trap plastic again. Dont worry about it being water tight as i said we need that water if it wants to come do work let it. Last we have to backfill the site with soil if you prefer source some top soil if your soil is of low quality and add 6 inches of top soil to finish. Now you have your "ground battery" it is time to design how you will use it. If it was me i would source not only solar pool heater panels but also like the content creator mentions a small PV array directly feeding 2 of those pumps. Solar DC to run the pumps and go not only under the soil or floor of green house but also to some 55gallon drums lining the north and east since i am in a northern climate. These barrels would be plumbed in the top of first one then out the first just 6 inches from the to top towards the second barrel in the chain into that barrel 6 inches from the top and a drop pipe to the bottom then repeat 6inches from the top out to third then 90 to the bottom rinse and repeat for all barrels. You can use a horse troth auto waterer or a toilet float valve or manually keep up with the water levels. The last barrel in the chain is return to the ground battery from the bottom of that barrel which will be your over head reservoir for your ground battery. I would temp control pumps coupled in all 3 ways barrel, floor, and radiator using the AC i would bring to the green house and contactor switches or set up deep cycle battery/ies and attempt using car relays and the available solar DC/DC. My one exception would be the fan on the radiator a common house fan is not appropriate for this use. I would rather source a squirrel cage unit from a furnace or other source forcing through the radiator using AC power from the grid and avoid the costs of batteries and hassles dealing with invertors and all that jazz. There are other option for the fan you could build a frame and use a fan with a shroud sucking through the radiator. Either way you suck or blow you need to pick the cold off the floor and blow it clear to the other end of green house preferably blowing from west to east or north to south depending on your orientation. No mater how you slice it the pump for the radiator and its fan are both needing more energy than im willing to pay for solar and battery to deal with. It is so much cheaper and more reliable to power them off the grid and displace the energy later with Solar grid tied with some micro invertors. One should have redundancies in the system so i dont think the AC power is optional if your looking at any issues for that radiator or solar to fail or just not produce a few days in a row. Those redundancies not only include the ability to increase solar heat, solar pv to a size to work but also a back up way to charge the battery, heat, and there comes the old school methods of yesteryear and that is to burn wood either inside the green house or outside of it to produce hot air from a controlled air space around the stove but to also be able to wrap that stove with copper and plumb it back to the heat line of the "ground battery"... You got 2 legs so everything you do should have 2 or more legs just the way nature intended it. Dont make your greenhouse hobble while you get to walk around freely. If you think displacing the AC grid power with solar it to expensive think about doing a ground mount but with a wooden pergola with rafters on 2 foot centers angled near 25-35degrees due south depending on where you live for me it is 34 degrees angle 10degrees off of south towards east. Then cover the pergola with uni-strut bolt panels to that with standard hardware from under side to the panel frame not through middle with fancy expensive hardware. Add some 350watt panels and enphase iq7a micro invertors per panel and enphase combiner. Dont cheap out on micros the ones that do 2-4 panels and cost 50dollars less are not your friend they are for solar fields and low wattage panels. You do need Qcables but, you can cheap out and use standard AC house with or THHN and standard boxes instead of there home run wires and expensive male/female adapters for your end of string run to the combiner box. You will save in many ways doing this you wont need the power for greenhouse except winter time, you got a new pergola to hang out under cheaper than any solar mount set up, you dont have to roof it, the enphase micros rarely die and if they do only that panel goes out. If you had a big honking invertor and it dies= no power and 3-8K gone. You dont need batteries saves enough for college right there. The system breaks even in 5 years since that is about when your big honking invertor would have broken and icing on the cake the micro invertors last easy 25years and since they make ac power you can run normal old AC wire back to the main panel you dont need all these little bits and bobs all the solar people try and sell and if you can build a greenhouse i put my money on it you can build a GREEN Pergola too. Mines 24x24 (actual 28x28feet counting angle and over hanging panels) from 16feet up my 2 story right to the ground looks like a A-frame house roof i got the bigger micros and bigger panels but that set up get you 900kwh/month easy under 20K for the entire pergola and solar if you do the work. Im now looking at my next move either mini split or point of use water heating its a close call since only 2 of us here im leaning towards the minsplit so i dont have to tote as much wood and she is leaning towards hot water thinking it will effect her shower in some meaning full way but it wont.. The windmill heat generator looks awesome but seem like a busy system to get right for me in the north here. Guess i will be stuck feeding the 700lb cast iron monster wood (ass-warmer 3000) stove in winter. Good luck to anyone that managed to read that far i hope your head is a full of ideas as mine is and your hands are capable to do at least one of those ideas.

Just some things to consider and need further research as well as testing in my opinion. My most significant concern with an aircrete project has been the potential for it to become waterlogged. In my parts we have a 6-ft water table and a relative humidity constantly above 65%. As I understand it solid concrete has a insulation value similar to adobe. ( R values are simplistic way of measuring insulate value however keeping it in common reference values, about R1 per foot. I've seen home tests that show aircrete having a potential r-value as high as R6 per inch ) As the concrete begins to soak up the humidity and groundwater depending on where it's placed the r-value goes down. I acknowledge that aircrete by definition has has bubbles of air in it and that increases the r value but also makes the concrete more permeable and as such fluids move through it more easily. As a middle ground the consideration for me has been styocrete, basically taking trash styrofoam then breaking it down to beads and blending that into the concrete slurry so that the concrete is acting more as a binding agent, although this still has the potential issue of a significant portion of those beads not being closed cell.

Ground-source heat pumps really are better for the climate here in Canada. Air-source heat pumps are great. But once they reach their limit, then their backup heating element has to kick in to provide the process heat for it to do its thing. The idea of having a solar thermal assist is even better. It pumps more heat into the ground. Solar thermal systems can be paired with ground-source heat pumps on the same circuit. Literally, all your home heating, hot water, and the heat for your greenhouse, or pool (if you have want) can come from zero-carbon solar and ground-source heat.

Nice idea. Unfortunately it isn't sustainable or ecologically friendly to build. Concrete is simply too high in CO2 budget and putting plastic into the ground just feeds the already very problematic micrplastic issue. Plastic degrades underground as well as outside. Bacteria and fungi will break it down and thus make it 'available' to earthworms and all sorts of other unterground lifeforms. With a 1000 year span to actually break down, such a build system will harm the local and regional ecosystem short and midterm. Long term it can also feed into the larger cycle. Are there alternatives to create this heat-trapping box that a) meets sustainable building material criteria, and b) isn't synthetic contaminating the soil food web?

So baised on this my understanding of this concept is as follows (and probably wrong). this is effectivly burried insulated box with two isolated closed Circuts. This means you require two water pumps. first pumps the liquid though pipes so that get warmed up by the sun. this water runs though the insulated box and radiates heat from the water to the ground... the insulated box keeps the head where it is in the ground Second pumps liquid from the box though a radiator/heated floring system where it redistributes the heat into the shop/green house. If this is correct my theoretical plan would be, start of by digging a hole 10 ft and pour a 1ft layer of foam-create. then 1 thick walls, 3 feet tall.around the parimeter. put the two circuts in the box, back filling with the dir you just pulled out of it 1 ft roof on the insulated box with more foam create build the green house on top of that the north wall of the green house should have 2-3 ft of storagethat can have a standard roof. on that roof, you run the pipes of the closed circut to pump heat INTO the insulated box I again would want two solar power systems aswell. one that direct powers the oen of the water pumps. it runs the pump that heats the box. the other connected to a battery pack to power the pump pulling heat out of the insulated box. again i could be horribly wrong with all of this.

Polar Night Energy is a company using sand battery technology too. It has a plant with 100tons of sand is producing heating for the city of Kankaanpää in Western Finland. That is just another example of a working model to tell them about when they try to tell you it can't be done. HINT: you can't have any moisture in that system. IT has to be completely dry sand and it needs to stay that way. If not you will be sorry, it will destroy itself from pressure buildup.

So how it worked out your system after one year? I always dreamed of such a system, but I live in a concrete box. But my idea was for the battery to be under the greenhouse. and the between battery and heated floor should be an grid like floor. aircrete for piles, and removable polystirene the rest. During the summer, the insulation will prevent overheating of the green house and lose of heat. During winter, insulation removed.

The solar, heated houses I’ve seen have a insulated storage tank inside the mechanical room. Trying to store your heat energy in the ground outside of the greenhouse seems like a huge waste. Maybe I’m underestimating the cost of the storage tank. My first thought was to circulate from the solar heat collector directly to the in floor pex. Might overheat during the day and not enough storage for the night.

This pipe manifold system is a good idea. Try combining these four Ideas. A sealed steel piping (melting Temperature of 2300 F) manifold a kilometer long or more with 25 percent of the manifold set flat above ground and the remainder below ground placed at the bottom of a compacted sand pit. Vanta Black or Super black heat paint to coat the above-ground portion of the steel pipe. Two custom-built Tesla valves that are mounted at each end of the piping manifold are set for input at one end and output at the other end, the higher the diodicity (number of restricting segments) the better. and finally the sand (melting Temperature of 2900 F) for the storage of the heat. The transfer fluid could be Air (capable of obtaining 1000F or more), water (boiling temperature of 212 F), or oil, (Depending on the oil used. Standard auto oil is about 525F). The Tesla restrictors in the closed pipe system cause the flow of material in only one direction based on the difference in temperature. The pipe material transfers heat to the sand for temperature storage. Extraction of the stored temperature can be accomplished with a passive or active system. Unfortunately, drawings can not be placed in youtube comments. Hope this gives food for thought to your excellent ideas.

everything is relative. My off grid cabin only had a small generator at 1st. I got the small Westinghouse quiet model. I added solar panels and a small battery. I still had to run the generator all night. Gas generators are initially the most convenient, but least cheap option for making power over time. I was producing more power from panels than I could store so I upgraded to a bigger battery. After that, the generator only has to run every 2-3 days or so to charge up batteries to >= 80%. As I increased my power generation, I also increased my power usage. At 1st, it was just lights and a computer. I used propane for heat. Propane produces a lot of condensation. The 1st Summer the generator ran the A/C directly. (not good for generator) The 2cd Summer, the generator only charges the battery. I now have a microwave and minifridge, upgraded A/C to dual inverter and new this year a small electric heater. I am in process of adding more panels and another big battery to, hopefully, almost never having to run generator. I considered geo thermal during COVID 19, but couldn't get any one to dig the trenches. I will again have excess power, but that will be used to charge my (PH)EV next year. I may revisit geo-thermal next year as I expand more. It is a continual process of learning and implementing.
