DIY: OFF GRID WOOD FIRED HOT TUB from IBC CONTAINER🔥

[@budspencer2658]

Hey. Make sure you use a food safe tote. I think these people used one that held spray foam insulation liquid chemicals. Dont do that. There are tonnes of food safe totes out there.

[@MacCustoms]

Yes indeed you want to be sure to know what was in the tote prior to converting them! Ours is a food grade tote; ours contained cornmeal prior to the reuse; we also recommend paying the extra for the ones already cleaned as it took us HOURS of cleaning and scrubbing to get it clean and disinfected!

[@budspencer2658]

@@MacCustoms so glad to hear. I was worried for a minute.

[@Girlsonadventures]

😍 So cool! I love how there is no electricity needed!

[@MacCustoms]

Right?! We love that it’s portable! We can easily move it down to our wharf or anywhere in our yard!

[@B.Cote39]

nice job guys!

[@MacCustoms]

Thanks! It was an awesome diy project!

Some sound and more details of what way you're doing it would of been sweet

I love it. Y’all got ur self a great time in a box I’m goin to build one my self thank u guy an lady

[@MacCustoms]

Thanks for checking out the video! Hope you enjoy your build as much as we enjoy ours!!

[@WithoutAPlan-nu5tn]

What an amazing thing to build! You two are so resourceful! I can’t state how much I enjoy your channel and seeing what you come up with each video! Also, the little goat is adorable just hanging out with you guys. Do you still have him? Haven’t seen him in any newer videos

[@MacCustoms]

Thank you for supporting our channel! The hot tub was such a fun build! Unfortunately, our little goat had since passed away 😭 he is greatly missed as he was always with us

[@steveb8269]

Love what you did with this guys...awesome

[@MacCustoms]

Thanks! It was a cool project and gets lots of use! Good conversation starter when anyone sees it!

[@advdan]

Hey guys, making one on a smaller scale with a log burner.. what’s the spacers and the circular saw blades for? Is that to slow down the heat running through the coil?

[@MacCustoms]

We just added those to keep the heat in there longer instead of having it rising straight up and out! We hope you enjoy this build as much as we did!!

[@michell12212]

Está súper cool

[@MacCustoms]

¡muchas gracias! nos lo pasamos muy bien construyéndolo (thank you so much! we had a great time building it)

[@JaapSmit-p3b]

I am wondering, since usually people put chlorine in their water for a pool do you also do this? If not, wont the water get dirty really quickly? If yes, doesnt the chlorine rust the pipes?

[@MacCustoms]

We would add a very small amount of bleach (4-6 cups only) and have not had any issues with the pipes rusting. It also stays quite clean where it’s making steam and the water is continuously circulating through the coil!

[@steightofthehart7899]

in fact copper doesn't rust but it does oxidize slightly while immersed in water - chlorine in swimming pool water at about 3 ppm or less should not affect copper pipe in any serious way - just make sure to have had a decent shower before dipping in the tub :) also something to remember .. bleach and chlorine are essentially the same thing (loved the vid)

[@MacCustoms]

Thank you! We appreciate the support to our channel! And very good points made! We haven’t had issues with keeping it clean!

[@MacCustoms]

8:56 shows how we used a 5 gallon bucket to shape the coil into a tighter circle then the purchased coil came in

[@hanshananigan1233]

Thanks for the video! Does the intake pipe need to slope downward from the tub to the firebox to activate the siphoning?

[@MacCustoms]

It doesn’t need to downslope but in most cases there will end up being one because of the elevation if the ibc container being lifted with the insulation on bottom and where the metal encasement has slight elevation to it and the coil will be placed on the ground.

[@hanshananigan1233]

@@MacCustoms Ok, thanks!

Thanks!! It was such a cool project!

[@quinnaiden66]

What parts did you use to connect the inflow and outflow into the tub what would you call that?

[@MacCustoms]

It’s a through hull fitting. They came from a boat supply shop

[@hahamorehaha6869]

How long do you expect the burn barrel to last? Been working on plans for a shower but i was going to use the gaylord to collect water that fills a barrel over a barrel for heat.

[@MacCustoms]

It’s been 18 months so far! When we have the tub heated we keep it heated for weeks at a time during the winter and spring , in the summer and fall it’s used less often but we will still keep it hot for a couple days at a time!

[@hahamorehaha6869]

@@MacCustoms thanks, 18 months and going is good.

[@armandniosi7657]

Did you have a problem with condensation? I built something similar, and have lot of condensation dripping into coals.

[@MacCustoms]

This is not an issue we had come across! Is your coil metal all the way into the tub or does it go from metal in the burn area to plastic lines into the tub? Not sure if that would make a difference but ours are plastic lines coming from the tub to the copper coil on the bottom intake line and then copper coil to plastic lines on the top input

[@armandniosi7657]

@@MacCustoms copper coils inside burn barrel.

[@MacCustoms]

@armandniosi7657 ours is an exposed coil currently but even when we did have it inside a burn barrel we hadn’t noticed any condensation issue. Sorry we can’t offer any suggestions as it wasn’t something we’ve come across

[@Nick-eh5ys]

Very nice! Which diameter of copper do you use?

[@MacCustoms]

We used 3/4”

[@chris4731]

The water just flows by itself? Or is there a pump?

[@MacCustoms]

There is no pump. It’s cycles by means of thermosyphoning! That’s what makes it completely electricity free and perfect for off grid use!!

[@vladimirivanov4964]

Такая тяжёлая что только краном выгружать 😂

[@MacCustoms]

[@bungjy1131]

Can someone point me in the direction of where you can get that copper tubing and how they coiled it?

[@MacCustoms]

The coil came from a local home hardware store. They ordered in the 60 foot roll for us. We used 30 feet for this coil 8:56 shows us wrapping it around a 5 gallon bucket to make the shape.

[@GrandmasterHobbyist]

​@@MacCustomsI imagine that was quite pricey for the coil

[@MacCustoms]

@GrandmasterHobbyist it was the most expensive part of the build. $500 approx for the coil

[@femylafi]

Why did you put those 3 saw blades in that section with the water piping.. is it to do with air flow? Do you need air flow in those fire drums? more than was shown, just asking because i want to build one. Nice video btw.

[@MacCustoms]

We used the saw blades to force the heat and smoke to work harder to get out of the chimney instead of being able to flow straight out! We would actually recommend scrapping the barrel and making the coil directly on the ground! We have another video of the “on ground coil” and it heats it up much better as the fire is built directly in the middle of the coil and not below it!!

[@philippj5176]

The fact that there is a goat checking out if you are doing everything correct brings that video from 10/10 to a 12/10

[@tippyzuk1]

Great job! Have you had to do any modifications since first build?

[@MacCustoms]

We did remove the coil from the barrel and it heats up much faster!

[@tippyzuk1]

@@MacCustoms Great to know for when I build mine!

[@MacCustoms]

There’s a video link in the description to our first build with the exposed coil! That one was much more efficient! When we removed the coil from the barrel we did end up placing it inside an eighteen wheeler rim to hold the coals around the coil. We are in a windy area and the fully exposed did loose some efficiency with the wind so we thought the barrel would be ideal but it wasn’t quite what we were hoping so we did the rim idea and that is A1!!

[@kema007]

How long does it take to heat it up ?

[@MacCustoms]

It takes about 7 hours to heat up in the winter

[@MacCustoms]

Once it’s up to temp we keep it going for a couple weeks at a time by adding a few logs every few hours. We also heat our garage and house with wood so we just check the hot tub at the same time we check the wood boiler for the buildings

[@DarkworldHero]

4:57 Is that a frakkin goat? 👍

Yes! That’s our belated dwarf goat Billy! He was present for any and all projects around the house, shop and yard!

Thats it put the wife in there to clean it out.

😂 it was not a fun task. We recommend only buying the pre-cleaned ones no matter what the price difference is! It took so long to completely scrub it clean

watch your long hair around any spinning things in the shop. No fun when a chunk of hair get twisted up in the drill chuck. Stay safe.
