Al. Before you pour concrete. While you have all the Plex radiant heat pipes exposed. Lay some tape measures down, fly your drone directly above the pad and take a series of photographs. This will give you scaled images (this is how photographers create scaled/ reference documents), you can use during the building processes, if plex location needs to be determined post the floor being down.
@@stevealldred4424 The grid is the right idea. However in this case they don't need to draw one on because the Lego block foam board has set distances between the nubs. Therefore all that is missing is the distance markers long the length and the width of the grid so the image can be mapped to the physical floor. If you then know the distance from the edge of the pad to the first row of nubs, and how far the rows of nubs are apart, you'll be able to scale the grid from the image later pretty easily.
I like the way your doing it. The idea of having the floor warm especially in the bathroom is great. With raiders along the walls leaves the center of the room cold.
On a long term project like this put your complete heat and air system in from the start. Over size for future expansion now will pay off big in the future. Always build for slightly larger than you need to have some wiggle room and not overload the system. What you do today will effect and determine your future.
We had radiant heat in a home we owned and we loved it. If you don't want to purchase the outdoor boiler just yet you could heat this small building with a small propane fired water heater. It doesn't take a lot of heat once you get the slab warm.
When you pour your concrete dont start at the outside edges. Start your pour on the green boards and work out to the edges. This way the concrete holds the foam down so concrete doent go under it. Hope this helps you. Roy.
One step closer to being at the OGP full time. Enjoyed Gina talking about running the pex lines. Glad she is getting more comfortable doing that. Since you asked, I would definitely plan for long term and get a boiler sized for all future needs. No sense in skinning a cat twice. Have a blessed week Lumnah family.
Al, that was a brilliant idea with the rebar and wood block to temporarily support your pex lines and sweep elbows. As a professional builder myself, I’m always interested in how people come up with solutions to difficult problems. Also, was very Skeptical about the spray foam working to glue those edges down, but it really worked well. Great job.
Hardwares ... spray foam is sticky as hell so good idea. My first thought was using 50 penny spikes to hold the boards down but this may work better. As for supporting the PEX, I'm not sure I would have used rebar but I certainly would have those elbows supported about an inch from the outside wall so they could eventually be secured to the finished wall. Each heating tube also needs to be marked as supply or return so the flow goes the way you want. Drawing out a route / plan of the pipes first would have saved a lot of zip ties. There's no good reason this can't be done without crossing pipes over each other.
Good morning, Al and Gina. It warms my heart watching you two working together. You both have the pioneering spirit that this great country was founded on. I pray God continues to bless your sweet family as you build your dream! It’s great waking up with the Lumnahs!!! Makes my day.
I think with the harsh winters y’all get you can never be overboard! After all, it’s not like you can ever get to that area again once building is completed. Good job!
Good morning Lumnah family, great planning for radiant heating especially leaving your food cellar section without heat. We don’t use much heating in the floors here in Az. Lol.👍😎
When I was a kid we made from scratch a Hassa log boiler and 60 years later it is still supplying all the heat, (for water and air) needed in the mountains of Washington to a huge lodge home with less than a third of the wood of a normal system. Hassas use sand and baffles to capture all the flue heat so only room temperature exhaust exits the system. Write me if you want more information.
before the concrete is poured take series of photos of where the pex pipe is running for when you lay walls etc, you'll have a good idea of what's under-neath and how much clearance you have, cheers great vids
Just as a suggestion, when you build your water supple manifold try using 2" Ts glued together. One T for each line then using reducers for your supply to each line... TTT something like that...that gives you a good even distribution to each line.
I agree 100% with you Al, there’s nothing wrong with the way you’re doing your foundation. Here in the U.K., we’ve been building all of our castles and houses (barring the odd few) this way ie with concrete bases and they have all stood the test of time. Your new home will be sturdy and strong.
Wow you are doing an excellent job indeed! You have a very good partner also to help you in your projects. All your building habits are very well and fully good. Continue in that way. I can't wait to see your new homestead and farming facilities in few years! Good luck and success!
Always planning ahead, aye Al? I so enjoy your videos.....you have no idea. Living here in China makes your stuff that much more interesting. I’m actually jealous cause you have such a great co-worker..... work water lines all day then go home and prepare a nice meal for the family! Very good, my absolute favorite......can’t hardly wait for your videos.... 😊
@@ryanhoward1013 Good evening from China Ryan. I live in a lovely city in the north named Dalian. It’s very different than the US to say the least, but this is a very nice place to live. City living if you get my drift, over 7 million people. 😳
You do your job that suits you and your happy with, never mind the critics. I enjoy your videos especially the cooking portion. Keep your good videos coming.
I think you are right about getting the boiler now but with having off grid power I would also have a wood stove in the buildings that have to have heat.
Hey AL, When you connect your tubing to your manifold, be sure to connect "Input" or HOT LINE to the tubing on outside walls first. Inside walls will end up being return lines. MARK THE CORRECT CONNECTORS NOW with a sharpie.
Al, there's been new tips and tricks that no one has thought of. If it works, Atta boy! If not... always a lesson to learn. I never worry about negative people. But like my tote mega failure for a holding tank underground... we live and learn everyday
Slab on a drained gravel site has been done since Frank Lloyd Wright. My house was built in 1972 like that in upstate NY, just like many others. No problems.
I really like your idea of a larger outdoor boiler to be in a "power house" area where you can run lines to any new structure. This is the same idea I have for my next "retirement" property. I agree, over size it for what you think you need now, but if you build a "power house" around it, then consider making the structure large enough to double your boiler in the future should you want to add on with other barns, hatchery areas, etc. Make enough zones so you can run hatchery areas for chicks but off or low idle in winter when you are not planning for chicks. Love watching this series on the mini-house. It give me learning so I don't repeat any mistakes or take advise to ""do it different" or "do it better" you make during this build, when I decided to do my build in a few years. As the saying goes, "“Only a fool learns from his own mistakes. The wise man learns from the mistakes of others.” ― Otto von Bismarck Great series and Gina is one heck of a worker! Gina you rock girl!
Glad to see you used long radius 90 degree elbows to insert & protect supply & return pex lines to manifold. Been a long time , but I believe we used something to separate out crossed over lines to keep them from touching. Please explore this prior to the pour.
@@broman9216 EXCELLENT idea! These Røde mics have been proven over and over and over and over. I'll bet they would be so happy with the grand results they get from having better quality videos because the audio is better quality. I taught digital videography for many years at the university and I found that, if the audio levels are correct, the viewer of the video will never notice. But, if the audio is off, the viewer has to either strain from insufficient audio level or wince when the audio is too much or distorted or is overdriven. Yep, get those wireless mics and never look back.
Good morning/evening to everyone around the world watching the Lumnah Family on the Lumnah Acres channel! Greetings from Kamakura, Japan! 🇯🇵 I hope the first week of autumn is going well for you all! I hope the Lumnah’s can pour the concrete soon, before it starts getting cold 🥶 🍁🍁! 😃🐶👍🏾
When you said you wanted the heat to go to the outside wall first but thought youd laid the pex incorrectly: No problem at all, when installing the feed push the hot water down what you currently think is the return line, REVERSE the flow, ergo it goes to outside wall first.
my first thought was to run it from the outside in, and when Al mentioned it, I thought he would pick it up and change it. He can also use separate valves to send heat where they want it.
Good morning Lumnah's and friends. Well, I think fall is in full bloom here in Omaha with temps down at night in the 40's and day breezes that have that nice cool bite to them. Love it! I hope everyone has a nice Autumn day today!
Good morning Lumnuh family & Critters, Happy Fall Y'all... Always look forward to the days that y'all have a video out!! It's getting more exciting with each video on the OGP. I hope that y'all have a blessed day!
You know what Al….as many years as I’ve been watching your builds….just ignore the comments….you put it huge amounts of research and planning before you pull the trigger so you just build…we’ll keep watching, enjoying and learning!! Over and out!!
Always a lot of *"I would have"* or *"You should have"* comments!!! Al & Gina do their research. Even after explaining why they do something e.g. about slab in this video, the *Keyboard Warriors* still make comments!!! Sometimes I wonder if they have actually watched & listened to the video!!!
Al has said many time that hew welcomes the comments. He never claims to know everything and is not arrogant. An example that a certain person should take note of.
Definitely overboard. But certainly more fun to watch. It's not my money nor my time so I'll just relax and enjoy. Keep doing what you want, as always. Good luck!
Hi Al and Gina, I live in Newfoundland Canada and the winters are cold with a lot of snow, my house is on a slab and I have radiant heat, I couldn’t tell you how it’s installed or even how it works lol, I can however tell you I love it and my feet are never cold and I’ve been living here for 15 yrs…great job with the build
Definitely go with the boiler now, Al & Gina! No time like the present when they are available and you can afford to get it, why not? May not be the same story down the road. God bless. Love watching your tiny home come together. I am learning so much!!
Plus the rebar and screen should be on top to hold everything down... just in case any pesky pex slips out of it's holders on the green foam system - Crete-Heat
Slab on grade construction is fine. I did my 14x24 shed slab on grade. I've parked cars, trucks, and tractors in it and no cracks. The only difference I have is the use of so much sand. A 2B base with a fines/stone dust to level the heat crete installation. Too close to the toilet with the pex and you might melt your wax seat out.
@@tommourick4046 ... if they put in enough tubing the floor temp can be as low as 75 - 85 degrees, with water temps maybe 10 degrees higher than that. Wax rings should be ok to at least 130 degrees.
A water barrier needs to be 100% complete, surprised a sheet of plastic wasn’t laid before the foam PEX sheets… all those joins will let water through especially as your land has a water table basically at the surface… good perimeter drainage is a must now but I personally wouldn’t rely on that. Guess we will see if damp is an issue.
Here in Florida all home slabs must be sprayed...but we have more bugs than most as well as subterranean termites that eat through concrete to get to a food source
I like the pex foam board you are using. Make it easier. The Floating slap method for the floor is not unheard of. We've used it up here in Canada lots of times. And some of those buildings are 40 years old or more. The one thing that we did and I'm sure you are to is put wire mesh as well as rebar. That way if it does crack the steel will help keep it all together.
Agree with the wire mesh and re-bar in the slab B.P. Lucky Al is not building in Australia, the gravel would have to be sprayed/drenched with pesticides to stop white ants and borers, plastic PVC as a DPC (damp proof course) under the slab, no foam under thickened floor beams, must be on solid ground, no cross over of pec piping and piping tied to the reinforcing mesh, chairs under mesh to hold the mesh up off the foam. This would all have to be inspected whether in urban or rural situations, for compliance and future insurance. Different codes, ordnances and controls for different countries around the world. Cheers.
Good morning. I would suggest going with the wood burner. Not sure if I would just go with radiant floor for my primary heating source. Hope everyone has a blessed day.
I love it that you know what you're doing because I'm definitely going along for the ride at this point. I'm completely lost when it comes to radiant floor heating, although I've loved the idea since I walked barefoot in winter on my first floor with radiant heat. Everything you set your mind to comes out great, though, so it's exciting to watch you guys work. And thanks to Gina for the meal ideas! You'd probably be surprised how often I cook a similar version to what you three are having.
Greetings from sunny Saskatchewan. We know people here who use wood boiler/radiant heat systems for their house, shop, etc. Definitely consider going oversize on your requirements, as you can plumb in future buildings without over taxing the system.
put the big boiler in now. they have some that top opens and you can dump logs in with your tractor. the saving in sawing would pay down the road plus loading it 2 times a day using tractor would really be nice. they cost a lot but you are young and by the time you get as old as me running forks under logs and sawing to side you need and dumping in top of boiler is really nice. wished they had them when i got mine 25 years ago.
I see you said that people were having an issue with the way you're doing you're doing your slab and frankly it doesn't matter what other people think it is a bit different because a lot of us that live in the North haven't seen that type of slab done that way before and I've done a few of them myself and we always try to get down below the frost line but if it works that way that's great that's why I'm watching to learn something new so keep doing it the way you know that's going to work it doesn't matter what other people are saying
It does not matter he must be doing something right he has past every inspection so far so if it is wrong who is it going to effect only al not u I think people will always find something to criticise others for but they need to go do it I think he is doing amazing job
No one is perfect at anything they do. Many channels have changed things due to comments posted that they didn't quite realize they did wrong. As you build, it costs a lot of money. The last thing you want is to spend a lot of money to have to rip it all apart due to a major mistake. Have you ever had a mistake that resulted in a sewage pipe burst in winter? I have. I wasn't the one responsible for the reason it burst, but I sure learned a lesson cleaning it up. That is why people will comment. We're not being mean, we're trying to help Al and Gina avoid a potentially costly mistake.
@@bazstone8885 it does matter when people from different areas of USA and different countries are watching, they are putting Al's work against what is the norm for them and if Al want all these people to watch him the he needs to put an explanation into why he's doing it the way he is as far as I see he's only getting 1 inspection and and he passed it. While in the UK he would have had to summit detailed plans and apply for planning permission before he started, then he would be inspected about 20 times throughout the build and if he failed any he would have to redo that bit. I totally disagree with somethings and the ways he's done them but if it's good enough for him, it's him and his family that will live in it and he has explained or mentioned them points then we can't ask for more. It's common sense to explain it he even knows that and has said as much.
