The Underfloor Heating Saga Continues... 

The amount of respect and patience you have in your communication with each other is what is sooo precious to me

Perfect execution 👍. It’s a joy to watch you guys work. Hope my advices was helpful. // Swedish Plumber

Wow! Your wife is a very smart girl! I'm fairly handy around the house. I've laid flooring, reroofed my home, moved doors and openings from one wall to another...but when it comes to electrics and plumbing I'm at a loss. My brain refuses to work that way! I'm a retired nurse and medical I understand. She has saved you thousands of dollars. She's a jewel...but I'm sure you already know that. Thank you for taking your time and sharing with us. 🇺🇸

Am I likely to ever do this? No. Is it interesting? Yes. Love learning how things work!

You have to keep the pressure in the pipes while pouring the floor because the pipe is expanding at 6 bar. When in use it will go from hot to cold so the pipe will expand and contract, that 6 bar while the floor is drying up will make room for expansion.

I enjoy watching you all so much even though I don’t have a clue what you are doing.😂

Guy and I both holding our breaths at the end until Kylie said "bye!" 😂

Those walls are looking fantastic in the background!

Bloody hell, most movie directors can’t make films this suspenseful. I was on the edge of my seat watching this!

I thoroughly enjoy your commitment to finding the joy and humor in the process. Looking forward to watching more of your journey.

love the snickering in the background when someone mentions "stubbornly" :D

Kylie Your comic timing on the "Bye" had me coughing and laughing for over 6 minutes. Every time I thought back to it I started laughing again. Informative and educational and hilarious too - best one yet.

Your openness and kindness are a welcomed by many. Refreshing 😊❤👍

Love your persistance, ingenuity and humor. Well done ! 👍

You both are so brave ! Congratulations on the test results

I remember the first time I allowed my son to use a sharp knife, hovering over his shoulder ready to step in. Bless him, your boy is really coming on, you must be very proud. Great work team, nothing like being the test case for a revised product with as yet unpublished install documentation. Thank God for the Swedes and hail to all the Dave's in customer support everywhere.

You two amaze me! Hats off to you both for patience and the will to learn. Keeping at it until it is perfect!

This video felt like watching a suspense thriller. I was rooting for you both

I love watching you both. You’re my innuendo fix for the week 🤣😂

Amazing ! I admire your problem solving skills, and I’m pleased you got it all sorted. I’d be absolutely rubbish and I’d have to call in “someone who does” 😉😊

Coming from a Fortune 100 background, the lack of documentation often means a lack of testing and quality control. When you hire a documentor (not just a Tech Writer) MAKE SURE that person (a) participates in the process from blueprints through Beta, AND make sure that person can be critical and ask questions as an end user would (the big 'why do Beta' reason). Finally if you do a 'Quick Guide' make sure it is entirely pictorial (i.e. multilingual) - IBM was doing this as early as the late 1970s! It saved thousands of hours of end user frustration!

Brilliant team work, well done both 👍

I am so glad the testing worked for you, it was like a detective story. I am dismayed that the manufacturer does not supply detailed instructions 😊

Love watching your programme, due to my age my knees would have given up by now. Well done guys.

You guys are amazing. I hope all that beautiful fruit isn't going to go to waste . Hopefully you can donate it if you can't use it. ❤️

*Kylie & Guy, that looked so complex.... but you achieved what you set out to do... now onto the next step of covering up all them pipes...*

Talk about EXHALE!!! Well done to both of you … Kylie I do so admire your ability to teach as you do 👏👏👏👏

You guys are so patient and thorough. About 40 yrs ago a plumber gave me a tip when doing plumbing: put a newspaper under whatever you're working on and you'll be able to see very easily if there are any leaks as there will be drips of water easily visible on the paper, just a fyi. Blessings

I was getting uncomfortable ocd shivers about the ptfe tape so I'm glad you got rid!

Filling a system can be done by 1st allowing one loop to fill regardless of whether the others are open at one end, the others will fill to a lesser extent. After 10 mins or so close that loop open another, once you have gone right through go back and do it again. Once completed open all and let it run for a while until clear. Its difficult to do only if you have low water pressure from the hose attached , try and prevent having any leaks on the hose too. You will hear air rattling in the system so use your ears and if you like run the hose your venting the system with into a bin so its under water so you can see the bubbles.

Patience❗ You Two certainly have that attribute💯.....Congratulations on the progres‼ look forward to the next video😊

Your determination & problem solving skills just bumped up to master level. After consulting the manufacturer & professionals & getting the proverbial shrugs, you two marshalled on! Very admirable, cheers to you both! 🥂

Kylie, you can now sell your instructions to the manufacturers since they haven’t managed to produce their own. 👍🏴󠁧󠁢󠁳󠁣󠁴󠁿

These systems are more complicated than one might expect. I watched a video of a DIY installation where pressure testing was done on the individual circuits before they were connected to the manifold, but they'll have to bleed air again and retest once they are connected. You saved that extra step. Manufacturers should provide better instructions!

This was both interesting and suspenseful. I will never do anything remotely similar--but just fascinating learning how you process it to complete the install in progress.

Držím vám palce aby se vše povedlo.Mnoho zdaru a zdravím z ČR

Congratulations on this milestone. Thanks again for sharing your experience.

I love your ability to keep learning, and, if you find out what you thought you knew is wrong (or, at least different), you're willing to say so and get on with changing how you work. If only all of us could be like that.

I have recently started watching your amazing program. Loving it ❤️ Much love from South Africa 🇿🇦

A few comments after having lived with an in-floor heating system for many years that I had upgraded to a modern modulating-condensing boiler. 1) An in-floor system is low temp compared to a radiator system - so quite different in operation. That is, variable water temps from 110F to 140F - compared to 160F for a radiator boiler. 2) I don't recall seeing "air scrubbers" installed at high points in your system, and my system was installed with two. 3) My system had a "fill" circuit hard-piped and separated from our potable water by a double check, back flow preventer (required by code since we were connected to city water). 4) Your system looks to have 3 circuits and I'd have guessed two to three times as many circuits for the size of house. The reason is to adjust comfort since the high mass in-floor system has a slow response and fairs best with more circuits to manage temps throughout the house. 5) Are you heating your domestic hot water indirectly from the boiler? I had a circuit for the indirect hot water tank, and then used a "pre-heat" tank in front of the indirect tank heated by an evacuated tube solar hot water panel. During the summer months, solar heated the water and in winter, the boiler augmented heat from solar.

Held my breath! Big pair of onions the both of you. Extra help of Gin and Tonic!

Man, you two are amazing!

Fantastic! Well done!

Good job guys!! 🫂

That was a daunting task. I would never even attempt to do something like this. I admire the two of you for your fortitude.

I was biting my nails and holding my breath on this side of the screen! APPLAUSE

This skill and the courage or determination to do something that you’ve never done before is essential in your situation being that working with a budget and also not having an abundance of trades that can do such a project in a cost effective way.

Congratulations on another milestone!

Thank you for working through that challenge and documenting it. As you say there is limited documentation of the actual process and what to expect at each step.I hope I am going to be watching the "professional plumber" do that for me but understanding the process and being able to say hold on " Is that right?" at critical points will give me great confidence in obtaining a good result. 👍

Congratulations!!🥳🥳🥳

Congratulations, and here's to bravery. Can't wait for the next bit.

love your dogged persistence. Great job!

What an achievement!! Well done!

Bravo guys!!!!!

Wow!!! That was quite a process. So glad you all figured it all out. Now on to final layer and then so many other endeavors . Great job!

I am very excited for you two. Can't wait to see the slab going in. You two are amazing!

Awesome! Great job, Kylie and Guy❤️❤️👏👏👏👏👏

Well done to you both 👏 for not throwing the towel in 😱 that was super tricky! It’s all coming together nicely! Will you be doing the same on the top level ? Good luck with getting the new part ! Good luck 🤞

Congrats!!!! You did it!!! This was really complicated!!!!

Yay we have underfloor heating. Woohoo onwards and upwards to next weeks video. You two rock!!!

Good morning, very complicated and complex, it's a good thing that here in Brazil we have a warmer climate ☺️ and this type of heating is not necessary. My son lives in Porto, which despite being in the north of Portugal, it's warmer there in the center, where you are. Congratulations 👏👏👏 I love watching your videos 🙏💚💝🥰. Hugs from Brazil 🇧🇷.

DIY HTD (How to do). Breaking ground on something new is seldom easy. Lots of lessons learned built on top of previous experiences. Did your thorough research. Went with gut instincts. Changed a few things. Voila it works. Congrats for sharing concerns, failures, changes and cautious, intuitive planning & coordination. Well done Kylie & Gus.

You Both are brilliant 😮 What a Tram 🎉❤

I hope someday someone's using all of youre knowledge and thanks you.

Anothe success, GOOD JOB!

fascinating. ty, i love ur logical curious mind

Once again you've solved aproblem and I must say you have the patience of a saints 😉

Excellent work Kylie and Guy! I too have given away tools only to need them later on 😬 The manifold I installed is a much simpler system - single zone. No actuators just an in-line water pump tied to a water heater. Commonly called a Taco pump stateside. 😀 Eric.

Thank goodness , success😄😄😄😄😄😄😄❤️❤️

Guys I am no plu.ber but did my own system by Installing everything and then just filling the system as on the bigger system (boiler or furnace or what ever heat source) it has a bleed valve that captures the air in the system automatically so not an issue as it removes the air during circulation. Yes no PTFE tape needed and a no-no on an olive type connection as the parts cut into the olive and the olive cuts into the pipe while tighting the fitting creating the seal.

Deepest sympathies! I know it's a car but when I had an MOT fail because of an airbag warning light, no info on Renault site, none in Haynes manual and I couldn't find a thing online of any use. How many models of the Renault Clio are there? Hundreds. It's good to know the basic principles you need to apply, have some signs of what to do and know the advice you are getting will work. This will help a lot of people who will want to choose a product they can see the installation process for - companies might be more likely to make their own videos for youtube and offer chat boards for customers to share tips. At leastyou didn't have to use geotextile. Maybe if there's a big leak, you'll do that then, but people are genuinely willing you on.

I really can't feel like the video has ended without Kylie's "Byyyyee!" in the end 😂😂😂😂😂😂

Uponor. Quality stuff.

I had zero clue what you were talking about because a) I'm not a plumber and b) the teachers forgot to teach us the vocabulary in our English lessons but I still enjoyed the video very much.

Hi, you have a Uponor Comfort Port DUO Smatrix Base Pulse (I think). Just went to Uponor site to check the instalation and user manual and I think you did the filling/pressure test the right way. It's stated the actuators are in the open position "First-Open-Function" and you should not apply power because they would close in 10 minutes. Yes the manual is of little help, Uponor is a high quality brand, but the manuals are rubbish, too technical and sometimes too short, you may need to check the thermostat manual for some functions. Also some important details may be lost when doing the translation, I've seen this before with other german brands. Overall you did well! As someone commented before, keep the pipes with operating pressure while pouring the floor. Oh, almost forgot: never sell tools! They're like an investment...😁

Well done both 👍😊 one question though, where is you pump going, you have probably said but I have the memory of a very confused goldfish 🐡😊👍

the connector for the pipe on which you put Teflon tape is called "eurocon 16x3/4" if you ever need to replace it, as a rule of thumb if you use a rubber gasket there is no need to put Teflon tape, the water seal is before threads are engaged, but for some fittings, there is no lip to put a gasket so you need to use Teflon tape.

I keep saying this. Good work guys

If you would disconnect all the pipes and put fittings and taps on your pipes you would be able to pressurise all your systems and leave the pressure in the pipes until you have laid the floors, good luck 🤞

I have nothing to say really, but I appreciate your content, and wish to help with the yt-algorithms.

Thanks for sharing, very challenging but a fully deserved win in the end. When that valve was leaking and you had to empty and refill, that's me each time I mess with/change my central heating radiators.

I have found that anytime there is a rubber O-ring such as what you have with the compressiion fitting it is good to use vaseline on the rubber and what that will do is keep life in the rubber and make it easier to seal, and also , if ever need to take it apart it is a lot easier. Vaseline is really a plumbers friend. Now as for teflon tape it is also a good product and is another preventive measure to avoid leaks. i think anytime you can avoid problems it is always a good thing.

I love your logical way of learning new skills. You certainly did a lot of research. Could you find a local supplier for the decorator caps, a local plumber ? Probably you don't have such contacts. Somehow I have confidence that you will make it all work. I am snuggled under an electric blanket after getting thoroughly chilled potting up some rhubarb plants into large pots of well rotted farm compost. It was a struggle due mainly to my severe back pain issues so I had to work slowly, which made it a long cold job. It's good to see your garden work in warm conditions, so please film some of that when you get an opportunity. Best wishes from minus 3C NE Scotland.

ottima spiegazione e ottime soluzioni. l'unica cosa che mi domando è se l'inerzia del pavimento radiante sia compatibile con il clima molto generoso del Portogallo # great explanation and great solutions. the only thing I wonder is if the inertia of the radiant floor is compatible with the very generous climate of Portugal

So many people have no idea of when to use and when not to use ptfe. I admire your efforts, but in all honesty what you’re doing is very simple. If you have the experience.

Interesting project. I note the amount of plastic that going into an modern house is staggering. Plastic piles on plastic mesh, held with plastic ties...

you can just power the electronics and close some valves while filling the others. fill by one of the sides on the manifold and purge by the other. might be useful to add an auto purge valve. if the actuators are 12v and normally opened, applying power will close them

Had to have a look at my underfloor manifolds and sure enough no Teflon tape! Mine are stainless steel though, but otherwise look identical. No leaks 5 years in…

I'd power up the manifold and change the actuators to close them all. I'd also gas pressure test before watering, but you may have done that on the previous videos.

I would recommend thread paste as an alternative for thread tape when connecting NPT threads like on your leaking ball valves. It has a cure time of 24hr but for me is a better option than ptfe thread tape. Loctite do a good one.

you should use the best. Wavin AHC 9000 wireless underfloor heating system Okay, it might not be easy to get in Portugal, you can take off the blue electric motors, then the valve closes, but remember where they are if they are paired with the sensor that sits outside on the wall..

I never had a problem with normal size houses by filling them altogether . The circuits must be layed in a proper horizontal way. And lets face it the worst that can happen is that one circuit does not heat properly because off an air bubble. You can allways bleed the circuit with that problem a bit more . I mean it's not so that you ruin the entire installation nothing can damage . What I do mis at your installation is a small auto magic air pot over time some air can come out off the water if you start heating the water . If that happens over time it can stop the circulation . I that you have a bit off room to fit one. Exactly where you say this is still leaking you can fit an auto air vent.

To me, and by the portuguese standards, you are not anymore diy' s, you are professionals. It's a shame that manufacturers sell products without proper instructions and the portuguese representants don't answer your questions. I am almost sure they don't know how to do it. Congrats and thanks for sharing.

Woohooo!

Just be aware that all those fancy remote controlled electronic "gadgets" will fail within 15 yrs. The failing always happens when it's not the good moment. We bought our house from a central heating installer that tried a lot of luxery novelties. They are all slowly failing. Window screens that have trouble to open or close, light switches with dimmer functions that fail, backyard remote controlled gate that refuses to open just when you are receiving 4 m3 meters of compost, and of course a failing electronic manifold in the middle of winter. Also the solar water heater tubes failed and had to be disabled, and a year later the very big central heating storage vessel (designed for use with solar water heating) started leaking.

Jeez, you'd think the manufacturer could make an effort to clarify how their product is meant to work 🤷‍♀️

👍

Yes, I was waiting to hear Kylie say BYE , perfect ending to your videos.

Interesting video, Im iompresed there is no option to get off thet electric actuators and manualy close each circle. Instend of bucker the plumbers use circulatin pump with canister for sunction to fet rid of air. greetings from pague cz.

I can't imagine why you can't find a cap. I mean all plumbing screw-on connectors come in standardized dimensions. Just take one actuator out and find the type of thread it is used. Then it's easy to find a suitable cap.
