Filling the Garage and Basement Radiant with Glycol - Day 4, Episode 46 [1-29-2021]

In this video, I fill the last manifold and all of the secondary copper piping, concluding the flat plate heat exchanger, with cryotek-100 Propylene Glycol. Not being a professional and being new to this, you will see that I was leaving the air vents open after shutting the pump off, which was letting air back in due to the fact that there was no longer pressure in the system to keep the internal sir vent valves closed. I realized my mistake later after this video stopped, and closed all of the vents. The final purge will be in the next video. Stay Tuned! To see the other days:

The playlist will have all of my videos in the correct order form start to present, regardless of the date I uploaded them. It starts with how I designed the PEX and Snowmelt Loop Layout, shows the process of installing the actual heated concrete slab, demonstrates how I did the math to calculate the boiler and pump sizes, installation of all of the components, and ends with lots of time-lapse of the system melting snow. It also includes snowmelt system startup and shutdown videos, as well as walkthroughs of the mechanical room, continuous circulation design and electrical system.
I will be uploading more videos of the system in action each winter, as well as several videos of the installation process, including soldering, filling with glycol, venting, etc. If there is something in particular you would like to see, please ask, and I will make a video of it.

Do you have any pictures/videos of your garage slab pex installation? I'm going to be imitating your slab setup with a remote heater, so specifically I'm curious how you accomplished the routing of the pex going down and out through the foundation wall from the slab rather than running the pex up and into the garage space like most people do.

[@DeckerChristopherJ]

Unfortunately I don’t have any videos of that install (it was back in 2010), but I do talk about how I did it and show some pictures in Part 1 of my Mechanical Room video here: ruclips.net/video/0eVSJDShuts/видео.html Basically, we buried a 6” schedule 40 PVC pipe running out the back wall of the basement and under the slab to about the middle. It then 90°s up. Once we installed all of the foam insulation board and wire mesh, I cut the pipe off flush with the top of the foam board. From there, I ran the pex down through the pipe and into the basement. I also ran hit and cold water lines for the garage in the same pipe. Once the garage floor was poured, the pex and pipe were completely covered, so from the garage there are no manifolds and you would never know the pex was in the slab. It works great! Let me know if you have more questions and I will try to answer them! Thanks for watching!

@@DeckerChristopherJ Thank you Chris! I have watched that video - twice - already, and it was the top down view of the PEX pipes disappearing into the 6” PVC line that triggered my brain to realize I could do the same thing with my garage slab! The picture shows the pex pipes just bending over the edge of the PVC and going down into the pipe - did you not do anything to protect the PEX at the bend? No 90* PVC elbows like people do when having the PEX come up through the top of the slab (as you also did with your basement)? And a second question if you don’t mind, did you fill the rest of that 6” PVC pipe with foam or anything before pouring the slab, or did you just let it fill in with concrete around the PEX?

[@DeckerChristopherJ]

You’re welcome! Glad I can help! So I did not use any conduit or bend supports as the pex enters the pipe under that slab because the angle was very low. As the pvc pipe travels out to the garage, it is sloped up for drainage, so by the time it got to where I wanted it to come up through the foam under the garage, the pipe was not very deep. I sanded the edges of the pvc so there was nothing sharp, and pushed the pex into the basement. Once all of the loops were installed (3 total), plus some pex for hot and cold water, I filled any remaining gaps with great stuff foam before pouring. I have pictures of all of this, but unfortunately RUclips won’t let me add them to comments. I thought about making a photo Vlog video of the garage build with a voice over since all I have is pictures, but I wasn’t sure if anyone would like that. Anyways I hope that answers your questions, if not, just ask! 😊
