Description

Note: This manifold requires 8 Loop Fitting Assemblies (please see below).

The Engineered Plastic (EP) Heating Manifold Assemblies feature isolation valves and balancing valves with flow meters, and come fully assembled, ready for installation. The manifolds are available in 2- through 8-loop configurations. The body ends feature R32 unions and the loop outlets have R20 male threads. The manifold mounts on a bracket (A2670006) that comes with the assembly.
For cost-effective, durable, hydronic radiant systems, Uponor now offers the Engineered Plastic (EP) Heating Manifold. This new manifold is comprised of thermoplastic, highperformance, advanced materials suitable for use under conditions of high impact, heat and moisture. Successfully installed throughout Europe for the past five years, Uponor now offers this innovative new product in the United States and Canada.
This strong, durable manifold is made of an advanced engineered plastic, which withstands corrosive environments and is unaffected by the rising cost of metal, making it an economical solution for all radiant projects.

Features and Benefits
  • Flexible, modular design for expansion in the field
  • Resists corrosion, pitting, scaling, high chlorine levels and ultraviolet light
  • Offers cost-effective solution to copper, brass and other metal alternatives
  • Attached flow meters provide fast, easy balancing for radiant loops
  • Offers vent and purge capability
  • Temperature Ratings - 140¦F at 87 psi, 158¦F at 72 psi, 176¦F at 58 psi, 194¦F at 43 psi
This manifold requires (8) Loop Fitting Assemblies:

PEX Loop Fitting Assemblies Options
Optional Installation Accessories:

Loop End Cap

TruFLOW Supply/Return Ball Valves

TruFLOW Supply/Return Adapters
  • TruFLOW Supply/Return Adapters
    These allow you to connect the manifold to your supply and return lines. The supply and return end of the manifold is R32 thread. Choose an R32 adapter that will connect the manifold to your desired application.
Actuators
  • A3030522: Thermal Actuator (2 Wire)
    If you want to use your manifold to heat multiple zones, you can purchase return side actuators that work along side thermostats. The actuators act as zone valves to allow you to use one manifold to control the temperature in different rooms independently.

Most Liked Positive Review

Nice Product

I had three of these - two with no actuators and controlled by zone valves and one with actuators. Product is good and easy to mount and to connect loop piping (I used all 1/2"). Suggestions: My manifolds were in a basement and most loops came from above so in order to allow the flow meters to work I had to pipe each loop down alongside the manifold, do a "U Turn" and enter the manifold from below. This takes up a huge amount of wall space (3 - 4 loop manifolds ate up 6' of wall! I've seen quite a few of these mounted upside down for this reason. The thermometers seem kinda cheesy and they simply snap into a recess in the manifold. Looking at the picture I assumed they were "real" thermometers with a probe in a well.

Trash

Return manifold leaking from the twist on head that relies on an o-ring to seal. It doesn't even screw in tight. Total waste of money. Gonna have to look at other options now.

easy to use with 1/2 tubing - we also used with 3/4 tubing. works great and I like to keep brand with brand - maybe overkill but this product is great and easy to work with.

Well built and easy to install

Everything installed with ease on the first try and a little tightening of a couple fittings is all it took to eliminate any leaks.

NO problems installing!!!!!

installed it on wall, very easy to do, no problems, no leaks (cold water tested only). I asunder the impression that you can only have 10 loops per manifold, but I think I saw somewhere that you can go up to 12. I have another loop to include, so can I still add that to my 10-loop system?

Q: I have an installation where the pipes are all coming from above the manifold. Can I install these manifolds upside down? will the flow meters still work?

The manifold shouldn't be mounted upside down, the flow meters will not work correctly inverted.

They can not be directly connected together.

Q: I am installing in between floor joists from the basement. I assume I can just flip the manifolds over so the tubing runs up instead of down. Can I install the supply and return sections separately as well? I'm thinking of a side by side or possibly with some distance between the supply and return

No, the manifolds must be installed upright. Yes they can be separated.

Q: Is it possible to use different size loop piping on the same manifold, i.e. 5/8 pex for my tank and shop floor and 3/8 for my starter tanks? The large tank and the starter tanks will be the same temp., the shop temp. will be lower. Thanks!

The EP manifolds cannot be tied together in series. You could tee both of them off of your main line separately, however.

Q: I am interested in using these manifolds with Rifeng pex, are the A4020500: 1/2" PEX to R20 Loop Fitting Assemblies compatible type b pex or only type a, if they are not compatible with type b would I need an R20 to copper adapter and then a copper to pex crimp connector?

Those fittings will be compatible with the Rifeng pex tubing.

Q: Can the EP Radiant manifolds be used to distribute hot water to cast iron radiators if they are plumbed in parallel?

They can be, as long as the system will operate within the manifold's specified temperature and pressure range and the manifold will be able to provide sufficient flow to the radiators.
