Description for Rifeng 050-300-OXY

Rifeng, the largest manufacturer of plastic piping in the world, has created oxygen barrier PEX tubing for radiant and hydronic heating systems. Oxygen barrier PEX tubing has the same properties as non-barrier PEX pipes, but it prevents oxygen and other elements from infiltrating and damaging delicate heating system components. For example, it keeps boilers from rusting. Rifeng PEX pipe is made of polyethelene which is cross-linked to enhance performance and maintain the properties of thermoplastics. Furthermore, this tubing can be installed in a variety of ways, such as using the crimp, clamp, or fitting systems. Rifeng offers a 25-year warranty on the product.

        I used this in a concrete slab, after completing this project as a homeowner I found I shouldbe used a 3/4 tubing for an ice melt system. the center to centers are 9" for 5/8 and 12" for 3/4 the 12" centers wouldve made labor much easier to tie the tubing to the grating

        We have numerous applications where the tubing size and the jointless quality available due to the length of the coil vs the distance from our control board to a distribution manifold is very desirable in our hydronic applications. However, this tubing is stiff, like all coil pex tubing, and the regular pex rings are very tight to get on, possibly due to the extra coatings necessary to achieve the oxygen barrier rating. Still, there are no real alternatives that use standard Pex connectors, so I do recommend this product as long as users understand the hassles of using it vs 20' straight lengths of tubing (especially since we are unaware of any source of straight length Pex tubing with O2 barrier status).

                                            Good, solid PEX for install. As with all PEX this attempts to coil when being installed, but the quality of the PEX is great and can take the temperature/pressure of my system with ease!

                                                  I used this tubing for the supply and return line on my outdoor woodburner. It has worked well and is of a very high quality. It is a little hard to get the bend out of it especially when it is cold but any heavy plastic tubing would be like that.

ProPEX fittings provide a wider inside diameter than any other type of PEX fittings. ProPEX tools are costly, so it may not be worth the investment for a small, one-time job.

It will be perfectly fine for a outdoor boiler setup at long as you insulate it very well to prevent freezing ..... As far as the taco pump running 125psi that might be the specs to the max psi it can handle , a hot water boiler runs at 12-15 psi anyways.

I want to run the 3/4" oxygen barrier pex for the baseboard supply and return and where else needed. I will have 100ft to 125ft in one series with about 40ft of baseboard heat. The second will be 125ft to 150ft with about 35ft of baseboard heat. My question is will I have enough flow ratio to BTUs running PEX instead of copper? Will it be enough to heat my approximately 1000 sqft home?

                                                                        If you are running separate lines to each radiator it is likely that the 1/2" PEX will be just fine.  The 1/2 inch PEX will typically handle flows up to 1 gpm easily and this equates to about 10,000 Btu/hr at a 20 degree temperature drop.   However, pipe size is best determined when you know the gpm and temperature requirement for each radiator.  For Example some radiators are rated at a flow rate of 1 gpm and 180 degrees.  If you intend to operate at a lower temperature using a condensing boiler the radiator Btu rating will be less than at 180 degrees and it may be necessary to circulate fluid at a higher rate to attain the needed Btus for that area.  I have some radiator circuits that are provided with 3/4 size PEX pipe simply because they need flows of 4 gpm or may be on circuits with several radiators in a series.  I know this does not answer your question but I hope it provides some background.  Here is a link to an excellent on-line manual

How would I make this work? Also if I have one loop on one zone this loop can be any length under 300 ft right?

There are systems in which shorter maximums should be observed and others in which loops longer than 300' would be okay. When loops have widely varying lengths, you should use a manifold with balancing valves to regulate the flow to each line.
