I’m loving the biogas videos man. Any updates on this system? Curious how it’s coming along.

[@maderightamerica3216]

You did a great job designing your syatem. I have the same system as you do. I had to redesign how I heat my biogas digester and my hot water because my greenhouse got way too hot in the summer months. As for winter time my system kept my greenhouse so warm I could keep my doors open all day long and get free heat from my greenhouse. I did do something different from your system, I put a hot water tank on my biogas digester so in the winter I had hot water flowing through it 90% percent of the time. It will take you at least a month before it will give you plenty of cooking gas. Again, I really liked your system. It was well thought out. Have a wonderful day!

[@ModernOffGridDIY]

Thank you and thanks for sharing. My system has been up and running close to 2 years now I no longer have to heat it at all just let the sun heat it and works just fine everyday I have gas. Just feed it and put water that's it. Our winters in Hawaii does not freeze or does not come close to it. Free gas everyday can't beat it.

@@ModernOffGridDIY so awesome! Great video. I’m on big island and am about to set up a biodigester so this video was great. Super excited. One tip I learned researching appliances to run off of the biogas/methane. The main difference is simply the size of the pilot holes dispensing the fuel. Like how natural gas stove has a smaller size pilot hole than a propane stove. The hole for a biogas appliance needs to be 3 times larger than it would for a propane burning device. I’ve got a double burner and tankless hot water heater for mine but also found some videos of people running a generator on biogas. Just need an inline pump to keep the pressure consistent. Anyway great video stoked this is working so well for you and I’m super inspired to get my system set up. Bless up 🤙🍀✨

[@shalomtoday]

​@@bigwavedave2655can you send a link to the type of inline pump you use for pressure.

[@ideasinprogress607]

Sure would love to see an update on how this system has done after your final changes and used it for a while.

[@seanavery7265]

That's what all country's should be doing ,man thanks for sharing looks great .🤔🕊️💗

[@ModernOffGridDIY]

I agree

[@martinbisschoff988]

Lovely. I have another idea too. That crawl space underneath the digester panel frame? Any greenhouse material left? Cover up the sides of the panel frame, add a few nesting boxes and pop in a few hens. Let them roam the yard daily. Free range eggs, extra brilliant manure for the veggies planned, and NO snails or bugs in the veggie patch. Also, if you add a rooster.....no 'alarm clock" needed to wake up! 😆Happy days, enjoy!

[@ExploreAmerica]

My ex girlfriends father invented that heating system you’re using. He was from Belgium at his house for Christmas. He had 2 heated rugs heating the whole house. He removed his furnace several years earlier.

[@rongray4118]

Ah! Had to get to the end of the video to know you were going to put a Greenhouse around your system! AWESOME!!

[@350pauli]

Awesome job 👍can’t wait to see the output

[@ModernOffGridDIY]

Thanks

[@rfotrader7503]

Hi, it would be more efficient if you put insulation foil between the soil & the pipe. Currently you are losing heat to the ground. Regards

[@estebancorral5151]

Compacted earth is insulation.

[@rolandsharp]

@@estebancorral5151 no it will completely absorb the heat. this is why it's so important to insulate when sleeping on bare earth or you will freeze to death. it's the most important thing when trying to survive a cold nigh is to insulate from the earth

[@Tiersmoke92555]

For heating the ground, you can bed your plumbing in play sand and give it about an inch of overburden to protect the bag from punctures

[@shaunshatto610]

Hello If I may make a couple of suggestion. The ground will act as a heat sink and will take all the heat away from your biobag. I would use some ridged foam insulation between the ground and your coil of hot water. Second water like to take the path of least resistance so your hot water will go through the first line and back to pump. If you make a zig zag effect to get your hot water over all the bottom your biobag. I love your Idea for heat. I was just getter ready to build a bag with internal heat lines and this idea it amazing. I hope my info helps you make more biogas.

[@marctorrades1760]

That's true , you should have isolated your heating pipes at list with 4 " or 10cm of isolation materials. All that effort and money for not much 😢

[@DylanDraper1]

A greenhouse over it is brilliant!

[@phillipperez3358]

That is HUGE. I was considering purchasing the home biogas 2

[@ModernOffGridDIY]

Looking back now I should have got a smaller one but the big one produce more gas.

Aloha Lou Thanks Awesome buddy.

[@simonmeszaros2770]

maybe putting a bag to the ditch would save some temperature fluctiation and even hold it.

[@zl2seazl2sea98]

I used 80 mm polystyrene sheets as insulation under mine with rock dust covering the insulation, I have 2 x No. 7 units

[@lennieadi]

Great video. Any update on its progress and use. I intend to install one. Saw this in Kenya. You’re the first western person I’ve seen with the similar system. Great job.

[@rongray4118]

Only thing I could think to do any further is to use an aircrete surround to protect the sides of the bag. Great Job!!

[@jimh4167]

Just a thought on the Thermo heater... If it had the exit from the diagonal corner .. it should force all tubes to get more even energy transfer Same way to wire multipul solar battery bank

[@parkermitchell6701]

Hey I think you said something about planting a garden under the solar panels I used to work at a solar company damaged panles leak out lead when it rains and I have seen undamaged panles eat the galvanized coating off of a tin roof. Also about how many gallons of useable gas does this sistym make in a year.

[@SaintTrinianz]

Great set up, hope it's working out well for you. Looking forward to updates!

[@ohoiboi9818]

I agree if you can plastic/rubber layer then rigid insulation under under pex will help. with heat loss and gains in performance and temp control.... Even a membrane layer under the pex will be a gain compared to bare earth

[@TheTeeDay]

Could this be used with a regular toilet

[@Tinman2955]

What ever happened to your other biogas digester? We never saw you start it up

[@DylanDraper1]

I’d use a Mylar/reflective vapor barrier right under the radiant heat pex, can this power an instant water heater? You could probably lag your exposed pex with an insulated/reflective layer too

[@strayobject]

One for the future project ;-) You should have looped the pipe under rather than cut and connect, this is stupidly more expensive than it should have been. underfloor heating is done in loop runs so that you don't end up having leaks. You could have saved loads of money and had 0 stress about punctures if you have done it that way.

[@ModernOffGridDIY]

I appreciate the thoughts but look at any water heater panels they not in loops it's a grid style also it's been working just fine it's been years now. If I was worried about the money which I'm not so that don't matter.

[@joecurmaci5880]

How do you clean it out

[@coborobasky2080]

Did you ever end up putting in the greenhouse?

[@gardenofedencoltd..3048]

Thanks for sharing Bro where can one order or buy one?

[@carlsmith2826]

Is it possible to over heat the fluid inside the bio digester?

How can i buy it in Pakistan. If not possible then plz guide me how can i build it at my farm.

[@oldtimeengineer26]

glad to see you back. How has your house come along ?

Good I even built an 5 bedroom house in 8 months in a different location didn't share it on KZbin but it was a big project. And purchased another home and more land. Setting my family up for the future.

[@350pauli]

I loved this video and I’m looking at the same thing any chance you can do a follow up video?

[@ModernOffGridDIY]

Sure

[@MusikCassette]

will you also use that to take heat away from the digester?

[@davidebarbe2350]

Great Job!! Which water heater model are you using? A 1000W one? I just bought the system and I will put a greenhouse plus a water heater on it

[@ModernOffGridDIY]

The water heater element I an using is 4,500w but wire for 120v so it running more like 1,500w but I have the option to wire 220v for the full 4,500 if I want. Hope that helps.

[@jeannettehall7324]

You don't need a circulation pump, put the solar heater in the green house, shorten the input output lines and let natural convection do its thing. Drain the line in the fall. Insulation needed between the ground and bladder. The joints are a hazard and too expensive. The water input line needs to be big enough for all those joint lines. The power of the flow weakens over all the lines and will only flow in the first two lines. One line switchbacked.

[@michaelefe785]

Should the inlet by covered?

[@STARFIRESOLAR]

I know you will probably never see this comment but I wanted to share some information with you about solar water heating. It takes 1 BTU to raise the temperature of 1 gallon of water 1 degree F. As a rule of thumb, Solar Thermal collectors yield Approx. 1000 BTU per sq.ft. area. that means that a 4 X 10 collector = about 40,000 BTU/solar day in winter. ( in full sun). You are attempting to heat 1,136 gallons of water with one 4 X 10 collector. Use this equation: Required BTU = Gallons X 8.3 X Desired temperature rise. Example: to raise the temperature of 100 gal. water 50 degrees F (say 60 F to 110 F) the calculation is 100 X 8.3 X 50 = 41,500 BTU. You are trying to heat 1,136 gal. of water so you will need over 11.36 times the output of your 4 X 10 collector to heat that much water in a solar day in winter. Also using the straight pipe method without using a proper heat exchanger will lower the efficiency of the system. Using a pump with a flow rate of say 2 gal/min will decrease the efficiency of the system because the water will not stay in the collector long enough to provide an efficient heat exchange and will return to the digester with very little change of temperature. Of coarse since you are not using the heated water like you would in a home water heater, once the water in the digester is heated to the desired temperature you would only have to replace the heat lost during the night. Insulation is key. Also the straight pipe set up with no flow-check valve and the heated water being lower than the collector, will allow the heat in the bag to be thermo-siphoned back to the collector and radiate the heat back into the atmosphere during non-sun hours and you will lose heat from the digester. Building a greenhouse around it like you want to do will also help heat the water and hold some heat in at night but you will still have the loss due to thermo-siphoning as I mentioned before. So I hope this information helps you.

what if I don't have a heating source, can the biodigester work?...I see several videos, not using any heating source..but the digester still works

[@ModernOffGridDIY]

Depends on your temperatures

[@tazsnoop1044]

As a plumber i see a problem with your manifold should hat a tee on the end not a 90 . The side with the 90 will flow but the others wont,

[@ModernOffGridDIY]

Thanks for your insight. I actually copied how my solar hot water heater panels are designed.

[@tazsnoop1044]

@@ModernOffGridDIY then the solar hot water system would heat better if you change out the 90

[@kevinanderson6979]

You need insulation under that radiant heating. You are losing all your heat energy to the ground. It's probably getting some heat from the radiant heating, but a night it's just going to be sucking it all back out. You would have been just as well off not having it there at all.

[@mlee81]

Sounds like a shitty job after all is set up. Pun intended

[@denisewiley410]

What size is that

(3 string bale is rated at R52...the floor heat should suffice.

[@derekkirsch6850]

Your heating supply grid is not going to work. The water will flow around the outside bypassing all the tees. You should of looped your heat link like a snake.

[@ModernOffGridDIY]

Its working been running for 3 weeks now. This video was taken a month ago

[@derekkirsch6850]

Intersting it shouldn’t have is it a small pump? Also how much biogas will it produce?

[@ModernOffGridDIY]

The pump has 3 speeds low med and high. I also put my hand under the biogas digester to feel the Pipes and its working well. The same way this is setup is the exact same all my solar water heater panels are built from the factory. 6 hrs of cooking gas on a double burner stove every day if I'm feeding it no more the 5gals per day. I stocked up alot of food waste before I started the project plus I have 2 other family's giving me there food waste. I gave them a air tight 5gal buckets and I swap them out for them.

[@montgomeryball5496]

It’s not piped correctly. It should be a continuous loop, you put tees everywhere. You’re never going to get even flow through each pipe.

[@ModernOffGridDIY]

My solar water heater panels are built just like this from the factory.
