Installing your own radiant heat tubing in a concrete slab. (DIY METHOD)

Installing radiant heat tubing in a concrete slab yourself can save a lot of money. Heating contractors charge a hefty fee to instal this tubing and some methods used are much harder and complicated than they need to be. Keep tubing lengths all the same and under 500 feet and run the tubing at 1 square foot of tubing per 1 square foot of concrete floor. Place 2" of closed cell foam board or 1-1/2 " of closed cell spray foam under the 6" grid wire mesh. Tie tubing to wire every 3' and pour your floor. If board foam is used make sure to place a 6 mill poly vapor barrier over the ground first. Do not pull tubing and wire up into the floor unless the floor is at least 8" thick. You will need the correct pump to push these longer loops but the extra cost is minimal compared to running multiple short loops that need to be balanced to flow properly. Thanks for watching.

I did my 30x56 post frame home by myself. Did three zones 2 bedrooms and main living room and kitchen. 8" of compacted gravel base first then Vapor Barrier with 2" foam board taped seems on top then steel mesh . Put the plastic towers to raise the mesh. Zip ties for the oxygen Barrier tubing. Foam around edges. I run it with one instant water heater. It's the best heat I've ever seen in my life you can't get more comfortable heat. Going on two year's of comfortable bliss lol.

By far one of the best videos on DIY in-floor heat. As simple as it is, you drawing it on a piece of paper made it all come together for me. I do have a insulation question though, I have a 4 foot frost wall. Some advice I’ve gotten is to extend the side wall insulation all the way down to the footing. I’ve already backfilled and was planning on just going from grade to top of knee wall (it sticks up 1 foot above grade) and butt the floor insulation up against it. Your thoughts? I’m also a bit confused about the insulation at the garage doors. The walls drop down here, and the top of the wall is level with the rest of the dirt. Thanks for any tips!

Just found your channel. I’m doing my research on radiant floors. I want to do something similar. Living quarters next to a shop with heated floors throughout. My question is how do you do walls and a car lift on top of a heated floor? How thick is the slab? Do you worry about driving a nail and hitting a tube when anchoring the bottom plate of a wall? You can’t glue the bottom plate can you? I assume even though the floor is insulated you would still need treated lumber and that rolled out foam under the bottom plate? If so I don’t see how to avoid nails and the possibility of hitting a tube. I haven’t decided between a 4 post and a 2 post lift. A 4 post could just be set and not anchored. But a 2 post would need anchor bolts. Would you lay out your tubing and just avoid where you plan to have the lift? Thanks Mark

Build a line spooler. You can do all of this work by yourself (one man team.) I made mine out of a couple scrap pieces of plywood with two ABS toilet flanges (adjustable ring) between them. One flange fits in the other to make your "Wheel". Use two 3/4" Black Malleable Iron Floor Flange Fittings and two 3/4" x 24" Black iron pipe nipples to hold the roll of Pex. Throw a 3rd piece of scrap plywood on top to hold it all down. Materials all available at HD or Lowes. Probably laid 300k feet of pipe in fifteen years with my 1st one. Retired it last fall and built a new one.

[@cmcintosh5004]

I really appreciate the work your doing sharing your knowledge. I never really liked doing concrete & subbed it out. My wife & I built over 20yrs, now do it just for our homestead. My wife had a few surgeries in her neck so she now dedicated herself to the homestead. I changed up starting a trucking business, plus if moving to another state (which we did) is easier with trucking. You mention the barn is for race cars, I'm curious if they thought out plans for car lifts? If so they'd want to put foundations in for those? I know trying to drill or cut into a heated floor afterwards wold be counter productive. There's pleanty of vertical space in a building like that for say double stacking cars depending on how many of course. Great work guys!!

[@Wingnut_Stickman]

Here is an idea that occurred to me after doing 4 of these systems: Rather than split the room into 4 quadrants for example, and run one loop through each, have each loop run through the entire room, spaced 5 feet apart. That way, heaven forbid one of the loops gets compromised even years down the road, you can still heat the entire room (not just 3/4 of it) with the remaining three working loops. I also discovered that "keeping the loops the same length " was not a "down-to-the-inch" requirement, and in cases where you cannot do this, you can employ a flow reduction valve (not exaclty like a shutoff valve, but similar) to introduce extra restance and balance the flow. When tying loops down to the mesh, I use zip ties, loose at first, so I can adjust things in case the layout is upset for some reason, loose ties are tightened as the plan resolves. I also close the system and air it up to a pressure of 20 PSI and have someone watch the gauge to discover if someone punctures a tube, but in fact, it has never happened thatone was punctured.

[@bondobuilt386]

Thats a pretty good idea to space the tubing out like that in case of an issue down the road. Yes you are correct I think even 20 feet is close enough for tubing length I try and get it close so it balances itself. Shoirt cheap copper headers is all you need. We have never punctured a tube in over 100 radiant slabs. I used to tie tubing loose with ties also but now I do my backwards trick from the manifold when getting close to where I want to be. Thanks for the feedback I appreciate it. 👍😊

[@Wingnut_Stickman]

@@bondobuilt386 You are welcome.

Is the 400ft due to the ability of the circulation pump? So if you run 3 400ft loops you gotta have 3 circulation pumps?

Is there different qualities of tubing what do you recommend? Really appreciate your videos. Thanks and hope you can find the time to help me out with information.

[@mr.wizeguy8995]

Counter flow layout gives most uniform heat on floor. Serpentine layout what you are using is uneven it's warmer on other end where water starts flowing hot into pipe. But does it matter on barn nope. But on residential house i would only use counter flow layout.

Hi Mark. Great to hear that my videos helped you build your own basement. That’s awesome. A little water under the foam board won’t hurt the floor any. Pour it at a low slump like a 5” slump and you will be fine. I’m assuming no more then 1/4” under there. Good luck buddy 👍👍

Thank you for the great videos ... I like the straight-forward explanations. I'm working on building a 36x80 barndominium currently in western NY.

I notice you lay down the mesh before the tubing. Can you explain why you go that way ... is the mesh for strength or just to hold the tubing down? Also, I'm planning to go 4" thick with my concrete ... does that sound good to you, and if so, what PSI concrete would you use? My garage area will only have normal everyday vehicles in it.

Great video. I think I've watched all your videos. I do have a couple questions. I've heard the wire mesh doesn't do any good if it's not pulled up into the concrete. I've also seen guys using the staplers to attach the PEX to the insulation. Will the PEX still heat properly if it's at the bottom of the slab? Would it be better to use the mesh and pull it up as the concrete is being poured with the PEX attached? Just want to get the most efficiency out of the in-floor heat. Any thoughts? I'm planning on 4" concrete/4000# mix. Thanks for all you do for us first timers!

[@bondobuilt386]

It works real good on the bottom of the concrete. Do NOT pull it it up or it will get damaged and you will get a leak in your system. I have never damaged a line or had a leak in 15 years of pouring radiant slabs.

Also, for this basic installation, what all pex tools (or other) are required? Thanks

Also, I wasn't clear on exactly how you determined 400' sections for this... it's a 1200sf floor, and most places say for 12" spacing to do 1:1 pex per sf, so I would have assumed 300ft circuits. You obviously know what you're doing, just curious if there's a formula you use for planning this..?

This must be one reason: Maximum loop length which is 250 feet for 3/8-inch PEX, 300 feet for 1/2-inch PEX and 400 feet for 5/8-inch PEX

What about nails when you want to build a wall or move one ? Won’t a Ramsey nail go through a tube?

Hey Bondo, Love your videos, especially the ones about radiant floor heating. I was wondering if you could do the same thing in reverse and use a chiller to make the rooms cold?

From what I remember that could cause condensation/moisture problems.

What pump and water heater do you recommend?
