Description for Rifeng RHM03

Features:

  • Flexible, modular and singular design system
  • Easy-to-assemble construction
  • Precise flow control and balancing
  • Fitting for both PEX and Multilayer Pipe
  • Control for the dominant heating systems like hydronic floor heating, fan coil heating or baseboard heating.
  • No Sealant or Teflon required
NOTE: Includes supply/return shut-off valves with temperature wells

This manifold requires (6) Loop Fitting Assemblies:

PEX Loop Fitting Assemblies Options
PEX-AL-PEX Loop Fitting Assemblies Options
Optional Installation Accessories:

Loop End Cap
Actuators
  • MA-ACT: Thermal Actuator for Rifeng Manifolds
    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.
Supply/Return Adapter Options

Note: Bleeder valves that come equipped with Rifeng Manifolds are 1" BSP Thread (manifold inlet) x 3/4" BSP Thread (outlet). If your application requires you to connect to a garden hose, you will need to purchase a Mr. PEX Manifold End Cap w/ Swivel Fill-Drain Valve separately which is 1" BSP x 3/4" Hose Thread

        Worked better then expected. Concerned about the quality due to previous reviews, but after receipt saw that quality was pretty good.

        Using this to heat a 28' X 40' area, using 1/2" pex tubing in a cement floor. Installed on 1-3-13 and seems to be working OK so far. Seems to be holding good temperature on the supply side. Could have had more elaborate instructions with the Manifold as far as adjustmens, etc.

        Nice product, crummy instructions

        Comments about 3-Loop Stainless Steel Radiant Heat Manifold:

        Considering the low price, the quality seems very good and the apprearance is truly excellent. There are however no real instructions or installation tips at all.
        I ordered a pair of the MA-75MPT adapters thinking that they would be needed to connect the mainfold to my 3/4 supply lines. Please note, that adapter is only used if you are eliminating the include ball valves and connecting directly to the manifold. The manifold outlets, and one side of the MA-75 and ball adapters are British thread. The other end of the included ball adapters is the more normal 1" NPT

        Good Value for the money

        Comments about 3-Loop Stainless Steel Radiant Heat Manifold:

        I have used manifolds from Uponor and Embassy and thought I would give these a chance. They are good, but the many union fittings make it difficult to get a water tight seal. The temperature gages are in the way of being able to get a wrench on one of the union fitting. With rubber O rings and nylon type gaskets, I am concerned about long term durability.

        Solid units, work well

        By Snowman

        from Salt Lake City, Utah

        Verified Buyer

        Comments about 3-Loop Stainless Steel Radiant Heat Manifold:

        I purchased 4 of these (3, 5, 7, & 8 loops) and installed them myself. I am not a plumber, but managed to get them in without too much difficulty. Do be aware that they are large (much bigger then the old INFLOOR units I replaced), but that they seem to be about the same size as other brands with similar function. They also seem to be less expensive due to the stainless steel bodies rather than brass.

        The units are very solid in construction, and offer excellent bleed / flush ports, and also valves to isolate the unit completely. The also have thermo-wells which is a nice touch, but i noticed that the body of one of mine was loose on the stem so I would not be too dependent upon their accuracy.

        Do be sure to check the size of your PEX hydronic heat lines (mine are 3.8" so I had to buy those fittings - the default that come with them are 1/2". Also, if you are using 3/8" PEX loops, my plumber (who I had check my work), suggested not to throttle the flow valves back at all as the flow rates are so low that any impedance could cause improper heating. He also pointed out that the manifolds themselves will distribute the flow well due to their large volume so throttling should not be necessary anyway.

        You should also be sure to use a 1" male brass fitting on each of the inlets and outlets (actually the valve body) as I was unable to get seals with copper fittings (maybe just me - again I am not a plumber, but the brass units worked perfectly first time).

        You should also be aware that the valve end of the manifold is a bit fiddly when it comes to leak stoppage as you have a sequence of a rubber seal, nylon seal and pipe thread all in just a few inches - but I did get them all to seal and I am sure better plumbers than I will do it without worry. You will need two large crescent wrenches (or a crescent and a pipe wrench) to tighten up this bit if you care about the final position of the valve handle and thermo-well (tough to explain - you will see what I mean when you do it yourself).

        I did have one fault on the 7 loop unit, and that was a very slow leak around the seal on the flowmeter. PEX Supply replaced the unit without question and the replacement works fine.

        Overall- good product, I only market the unit down due to the one leaking flow meter (which required removing the whole unit from a very tight opening in a wall cavity in my home), and the unreliable thermo-well.

            A:

            Yes, it comes with both the supply/return shut-off valves with the
            temperature wells on the left side of the manifold and the swivel drains on
            the right hand side.

          stainless compatible with domestic water? (open system)

            A:

            Yes, the stainless steel equipment is 100% safe and compatible with the
            domestic water when the stainless steel has a certain type of alloy, see it
            with the dealer.
            Besides, I can say that all food handling is mostly done with this
            material. So if you have any questions, discard and dare to use it.

            A:

            Yes, but for domestic water a different type of manifold is used
            without flow meters.

            Additional fittings are required. They are part MA-50P, which are included with the RHM03-50PK package.
