The Most Efficient Greenhouse on Earth | $100 a year to heat in -40C with Sand Battery Thermal Mass

[@patrickbos825]

The best thing about Dean is that he is just a real world guy with real world experience that built a greenhouse that works for four seasons. He's not a consultant trying to sell something and i proud to call him my friend. I couldnt have built the greenhouse without his ideas.

[@aistodiaolore9]

Well done man! Awesome build and the sand battery idea is brilliant. I'd love to see more of these kinds of greenhouses. Hope some day I get to build something like that here in Greece.

[@calysagora3615]

Great job, man! Not just copying Dean, but making it an iteration with other solutions and improvements that now others can get inspiration from . Here in Spain we need to figure out how to keep excess heat and sun away and increase humidity and fight water scarcity. Prevent our fish from boiling, maximize rain water harvesting, etc.

[@toddvillanueva6699]

You are 100% right about Dean...I really think this is what KZbin and online stuff was dreamt to be about when it was dreamt to be used in positive ways...I think everyone is surprised that Dean is not trying to sell his ideas or "secrets" and his time but just using his internet channel in a real humble way to show how proud he is of what he's doing, some passion, just being a real guy, and getting some enjoyment from it...those are the best types of channels and content on the internet anyhow through miles and miles of garbage and wastes of time that is on-line mostly... you have to weed through all that noise and distraction to find the good stuff, but it's there!...and you guys are adding to it... I'm sure people are so grateful for this content, in a time when we crave authenticity and just good decent people.

Thank you so much, Dean and Patrick, for showing us how to heat a greenhouse in a cold climate. We live in Norway at 59 deg north, so our climate is pretty much like yours, but with a bit milder winters. We reached -28 deg C in January this year for the first time in decades, usually it goes down to -17 a few times each winter. We have slightly shorter days than you in the winter (but very long summer days!). We have started to build our greenhouse at the south wall of our barn, so it will look pretty much as your greenhouses, 20 m long and 5 m wide. And now I know how to make the thermal mass floor thanks to you guys! So as soon as the rain stops and the ground dries up (frost has gone now), we can start digging and insulating for the thermal mass floor. Looking forward to have a greenhouse this winter! Greetings from Norway

[@ArkopiaYouTube]

Great to hear. All the best with your build. Sounds great. 👍

[@saethman]

:o Tenker dere å varme opp med ved, solceller og/eller solfanger? Etter hva jeg forstår så kan det være litt ekstra utfordrende her på berget siden vi har mindre solinnstrømming vinterstid når vi trenger varmen som mest, men noen harde tall i så måte har jeg ikke sett. Jeg har derimot sett noen få videoer hvor man har et "teppe" i tillegg - dvs at man senker et isolerende teppe over vinduene/taket om natta (og kanskje også på kalde og overskyede dager) for å redusere varmetapet (et tips da kan være å ha teppet på innsiden, hvis ikke så kan de fryse fast og/eller snø ned, selv om det er litt mer styr)

Bees want to travel as far as it can and then working home. I worked on driving milking truck from farm to diary and we do the same as bees. All route is to drive to the farthest from diary and then work home. Then i only needed to drive from the closest farm full with 42metric ton milk, total 64 M.ton (Sweden). So is no wonder they flew to the window. The only bee who is "smart" enough to understand windows/greenhouse i have seen is leafcutter bee. I hade wild leafcutter last summer in the greenhouse, they maneuver opening like a smart animal. They never ever did "smash window" as other insects, with a big leaf cut under them (same size as the bee). I really love leafcutter bees. Hope her babies survived the winter in my greenhouse.

[@PatrickPurtill-qb3mm]

Dean - I have to comment on your solar panels. Use them to power a Heat pump and kill two birds with one stone. Remove excess heat and reduce the humidity in the Greenhouse by using a heatpump. The hot water discharged from the heatpump would be as good as the solar evacuated tubes but no need to use glycol. In my last two greenhouses I used PEX Heat Transfer Plates on the ceiling to do this, but my next one I plan to also use a heatpump (I did use a radiator and fan with good results). A pool heater heatpump might be overkill - but it is what I am looking at. I also use a lot of iot devices to automate things so you do need to have wifi near your greenhouse.

[@ArkopiaYouTube]

Interesting. Heat pump right inside the greenhouse you’re saying. Nice

[@PatrickPurtill-qb3mm]

@@ArkopiaKZbin Yes A/C the Greenhouse and store the heat for later use - for every watt used you should be able to pull 4 watts out and get about 5 watts of heat to store. The key thing is you do not need to open windows for fall, winter and spring - you can fully automate it. You only need to use it when it is sunny - and you always have solar when it it sunny. There will be a few variable that will needed to be worked out - you water storage system of 10 totes stores about 12KWh(40KBTU) / degree C, that should be enough to help balance the highs and lows.

[@SeekingBeautifulDesign]

If you take that route and don't have other CO2 sources (humans in greenhouse, humans in attached house, pets, mushrooms etc.), consider HRV or ERV for air exchange because you run low on CO2 if built well. Can also do earth tubes for fresh (CO2) air in and then heat pump treat the outgoing air to scavenge heat. Another nice thing with the heat pump approach is that you use the condensation (soft water-like rain) for watering. Make sure your air contacting heat pump doesn't have lead solder around the fins (or other heavy metals). I tested the condensate off my heat pump and it had lead leachate. Also, depending on your spore load, you may want fresh air exchange or some sort of air filter.

You mentioned that you had concerns with moisture levels increasing, and that the incoming cold air from the outside was too cold. Have you ever considered using a "Heat Recovery Ventilation" system? (HRV). This unit will effectively extract the heat from the greenhouse exhaust air, and put it straight into the dry fresh incoming air (Approximately 80 % efficiency). For example, in my house when the outside air is at minus 15 degrees Celsius, the incoming air gets preheated (just by air exchange, no heating elements) to plus 12 degrees Celsius. Hope this helps! Mine in my house iis a "Venmar". This would likely work well for your greenhouse.

Awesome video guys - thank you! Really appreciated that it is a Canadian build and shows that a greenhouse like this can be a reality in our cold winter climate. I was even more excited when I saw that it was built in Alberta. Incredible engineering. How deep is the garden (soil) inside the concrete?

I put 3ft of soil where I grow in the ground

I will be emulating this build! Very clever!

Get er done. 💪✌️

I'm trying myself for 3rd in Ontario. :-) Friendly competition for a better future! (No sand battery, though. I have other ideas...)

​@@leofortey7561 I'm very curious Leo. ;)) ps I'm interested in biomeiler and biogas/bio digester

Amazing setup, thanks for showing this architectural masterpiece..

I know you guys talked about the math about a sand battery so i just wanted to elaborate on it for everyone. The specific heat of water is just over 5x as high as sand by weight. BUT sand is about 60% heavier than water give or take how coarse the sand is. That means that by volume sand is about 20-25% as efficient at storing energy as water. So when you lay your tubing in the sand to exchange heat it will increase your efficiency the more total volume of water you can have trapped with the sand in the tubing. Also for the wood stove if you had included a heat exchanger with a liquid media you would be able to heat the sand that way instead of trying to heat the air

So cool :-) You are a inspiration. I hope the birds are able to fly around in the greenhouse 🐦
