        I have used this tubing for two projects now for retorfits in my home. One was with joist tracks, and the latest is with warboard in a gut job in a 15' x 17' room.

        When I did the joist track retrofit, I had a 300' run that had to be threaded through all the holes that were drilled in the joists....what a PITA. This, combined with the fact that it came in a cardboard box (and my lack of experience), it was very difficult to unwind it and keep it from getting all tangled up. but we got it done. It was a two man job.

        The most recent project was very easy, used warmboard. The latest stuff comes plastic wrapped, you pop a hole in the center of the packaging, and it just snakes out and uncoils perfectly. I have a home made uncoiler (lazy susan and some 2 x 4's and vertical dowels), this was a one man job that took less than 30 minutes to install in the warmboard. Great packaging now!!!

        I have also used pex-al-pex before....I would not waste your time with it vs. hePEX plus as the ease of working it makes a HUGE difference. I don't know how you could use pex-al-pex on a joist retrofit system with a long run.

        There could be benefits to pex-al-pex that I am not aware of, but I won't be using it in the future. Only the hePEX for me. Plus it uses standard PEX fittings, makes it super easy to connect.

        Do not try to run multiple 3/4" hePex through a small chaseway by yourself. I just ran 350ft. of hePex in my basement ceiling then into 8 radiators , and it was not pleasant. I work in construction, and if someone offered me 3 days of either; pulling 3/4" pex, or pull heavy gauge electrical wire, or doing roofing or pouring foundations, pulling 3/4" pex would be my last choice. This stuff is not your garden hose. Pex is flexible, compared to black iron, or concrete, but this is all relative. But honestly, threaded pipe is easier on your shoulders then pex, not faster mind you, but easier. Would I use this system again? definitely, but with help next time. Actually, I am looking forward to using the 1/2" aquapex to replace the copper in my house (that by myself). That has to be easier. Good luck

        Great product! I installed about 1500 feet of this pex in my basement slab. Went down very easy, I did not get one kink as I have had with other pex. I recommend the tubing uncoiler for big projects. I just started using uponor and propex fittings and they have been great so far!

        Comments about 1/2" hePEX plus - (1000 ft. coil):

        I used this to install heat under an existing floor in between joists. Doing a detailed layout and installation plan is key. Taking out a bunch of tube to get around an existing duct is a pain. However, that is operator error. The tube used with Joist Trak was easy to install. Highly recommend the Pex tube uncoiler by Wrisbo. Life saver!

                    Ordered 100 ft of heat pex and received it two days later. Great product delivered fast. I also ordered items in the past and basically have my own pex supply in my garage. They have everything you need and will get it to you fast.

                          One good thing about this product is that it is slightly more rigid than pex for domestic water. My supply/return temps are 165/140 so I was expecting the hot water would make the pipe more flexible and that it would sag in long runs... it does not. There is an entire unsupported corner of it, maybe 12" each side, it does not sag. I was surprised at that. If you're running it in the ceiling, you will of course, want to add talons maybe every 16" or so, but in general its a strong pipe. Enjoy.

                                The great flexibility of the tubing makes a lot of difference when routing in tight spaces. The memory effect of pex-a allows to fix kinks with heat gun only.
                                If you have to connect this to a copper pipe make sure you buy wirsbo propex fittings as they provide better flow than a big box stores fittings as they have larger inside diameter. One can use a heatgun of a special tool to pull the tuping over the fitting.

                                                        My first attempt at using pex tubing to install radiant heat. I drilled 3/4" holes through the floor joists. Even that much larger it was a lot of work to pull the tubing through the floor joists.

                                                            It will probably work. however you will most likely need a reducer to 3/4" to get into the heater itself depending on what the unit you are running to looks like (ie: wall mounted radiator, baseboards, etc.) I WOULD absolutely consult a professional HVAC company for advice before you purchase this item or begin your work. For me, they were nice enough to help me come up with a plan give me a supply list, then I did most of the labor intensive work (running lines, hanging boards, etc.) then they came in at the end, added the circulator pump and made all the final connections. It was a great way to save money. Hope this helps.

I don't know any details about your setup so this would be my best guess. What size fittings do you have on the boiler? Or what is the max size pipe you could go on the boiler?

                                                          I'm remodelling my basement and need to relocate the piping for my first floor hydronic baseboard heat (which is located in the basement ceiling). I have used PEX to replace all of my hot/cold water plumbing and would prefer to replace the existing 3/4 copper piping for my heating system with PEX as well. I have two questions:
                                                          1) Is the 'hePEX plus' suitable for this application and if not what should I use?
                                                          2) Can I use Sharkbite press-on connectors with this tubing?

Just double check the sizes of the hepex vs. the copper because the way they size them is different.. I did most of my hydronic heating loop with this several years ago and no problems. I cannot help you with the sharkbite part of your question as I did not use that type of fitting.

                                                            I do not recommend use any plastic tubing for baseboard hydronic heating because working temperature may be up to
                                                            208F. This temperature make Uponor tubing very flexible and soft. If plastic tubing must be used allow space for expansion and retraction , no sharp edge against tubing, plastic clips hold tubing every 12". I never use press on connectors on Uponor tubing but if Your fittings design to use on cross linked polyethylene(PEX) tubing You may use them. Uponor made superior quality PEX tubing. Thanks

                                                            From a web search:
                                                            "Pex is okay for direct burial, but most people sleeve it in some CPVC for ease of maintenance if the need ever arises. If not sleeved, it needs to be buried in soft dirt or sand, no rocks in direct contact/etc.
                                                            Where are you located? 36" is fine in parts of the US, but in the north the frost line in many areas is 48" and so water lines are typically buried about 6' down. You could very well be in an area with 36", just not sure"
                                                            My personal preference is 160 psi polyethelene black pipe, which is rated for direct burial.

Hepex can not be used for potable, only for closed boiler systems. If Your house need longer then 100' line You can use larger tubing size. You can use black polyethylene tubing with 160 PSI pressure rating to save money. Thanks

                                                            There's nothing stopping you from physically doing so, but if it were me I wouldn't. I would bet that using anything but propex fittings would invalidate your warranty. Also, I don't know if the outer diameter of the two are the same - since the fittings for HePex go inside the Pex, the O.D. could very well be different from that of the Viega Pex. I would personally stick with one vendor for both the fittings and Pex.

                                                            It seems 30 days is the stated maximum exposure to UV before the Uponor warrantee is invalidated.
                                                            Check out the following link - it is basically the same question asked on the Uponor website - answered by a "PEX expert".

                                                            Obviously, less exposure is better and none is best, but figure on some exposure during delivery, etc. Don't leave it outisde uncovered for any length of time.

                                                            are going to use this tubing in conjunction with a wood burning stove. The
                                                            tubing has a max heat rating which means it will melt if the water gets up
                                                            to a specific temperature. Look at the product data sheets for the HePex.

                                                            A:

                                                            I have a wood-burning stove (ThermoControl wood boiler) and I have installed a radiant system with some Wirsbo hePEX for pats of it.
                                                            it really does not matter the brand of heating PEX you use as long as it is rated for hot water.
                                                            That being said I don't think it is recommended for connection directly to the wood boiler.
                                                            I would say that because the metal parts of a wood stove or boiler can get hotter than the temp of the water (which is regulated by the aquastat.)
                                                            Also, there are several key devices which must be mounted on the pipes coming in and out of the boiler... low water cut-offs, air-vents (big, heavy ones), valves, not to mention pumps with flanges (heavy) - obviously you could anchor the heaviest ones to a wall but that is a lot of anchoring to do. When PEX gets hot it gets pretty soft and will not support weight.
                                                            I have black steel pipe running in and out of the boiler to the pumps, vents, several valves, and right up to a hand-made manifold where the temp has been lowered by a mixing valve - then I run larger diameter PEX to the remote Rifeng manifolds. The remote manifolds then have several runs of 1/2" PEX going under the floors.
                                                            Does that answer your question?
