2-branch Stainless Steel Radiant Heat Manifold Set w/ 1/2" PEX adapters
1/2" PEX adapters are included by default. For other size adapters (free upgrade) make a note at checkout.
2-branch, Premium Radiant Heat Manifold Set with 1/2" PEX adapters (Supply and Return pair).
Pre-assembled, pressure tested and comes with everything shown on the picture, including 1/2" PEX manifold adapters.
SSM102 set is typical for areas with a total of 450 - 550 sq. ft of space, when used together with 1/2" PEX tubing (installed 9 - 12" on centers).
Complete list of components:
(1) Supply side radiant heat manifold with (2) flow meters and (2) PEX tubing outlets - lower manifold w/ red shut-off valve.
Flow meters allow to monitor the flow of water in GPM (Gallons Per Minute) through every manifold's branch.
(1) Return side radiant heat manifold with (2) manual balancing valves and (2) PEX tubing outlets - upper manifold w/ blue shut-off valve.
Manual balancing valves allow to balance the radiant heating system and are used to regulate the flow of water through manifold's branches.
(2) 1" NPT isolation shut-off ball valves with 1/4-turn color coded handles and built-in replaceable thermometers (both F/C readings displayed).
Allow to service the system and monitor supply (incoming) and return (outgoing) water temperatures.
(1) Automatic air vent to eliminate air from the system.
Air vents are used to eliminate the air from the radiant heating system, prevent air traps and enhance overall performance.
(2) Drain/fill valves with 3/4" garden/drain hose connection and a cap.
Used to purge/fill the radiant heating system.
(2) Manifold mounting brackets with bolts.
Superior bracket design offsets the radiant heat manifolds from the wall and allows for easy access and fast installation.
(4) Compression-style adapters for 1/2" PEX tubing.
Radiant floor heating systems:
Reinforced Concrete Slabs (4 - 6") - garages, warehouse, storage and manufacturing facilities);
Non-Reinforced Gypsym or Thermal Mass Slabs / Thin Slabs (up to 1-1/4") - radiant heating floors in residential construction;
Staple-up Systems: stapled to the bottom of the subfloor between joists - with or without heat tranfer plates;
"Sandwich" Systems: installed between the subfloor and finished floor - with or without heat transfer plates.
Snow and ice melting systems:
Snow melting systems for driveways, walkways; roof deicing applications.
Technical specifications & compatibility:
Total number of PEX outlets: 4;
Distance OC (On Center) between PEX outlets: 2";
Overall height when installed: 14.5"
Overall width when installed (with shut-off valves): 10.75"
Distance between supply and return manifolds: 8.25" OC.
Compatible with all types and brands of PEX tubing (Bow, Viega, Watts, Zurn, Everhot, Nibco, etc.)
Other suggested components:
To pressure test the radiant heat manifolds, use a Pressure Test Kit (SKU# TESTKIT).

Pretty Good for the Price
Ordered and installed over a year ago and the manifold is still going strong. I have 2 other different manufacturer's manifolds in the house and this one is by far the best for the money. The fact that it comes with everything and is still far cheaper that anything else is great. Everything works, everything fit together no problem. Originally came missing the fittings for connecting to the loops, but emailed pexuniverse and they were very helpful in sending some out.
Not as good a quality as my 5-branch manifold, but at half the price as that brand it was a good deal. The threads for the garden hose connections were poor enough that I wasn't able to tighten the garden hose enough to seal. Because of my set-up it wasn't absolutely necessary to use them so I didn't. For the price I paid I am happy with what I got. One of the thermometers was slightly bent but it still works so I am good with that.
I actually found the 2-branch manifold to be a terrific value for the money. You would be hard pressed to self-build a manifold with everything that is included for the one money-- flow control valves, thermometers, shut off valves, etc.! Since I was using 3/4 PEX lines, the only complaints I had were that the manifold supply/ return connections came with 1/2" fittings, making it necessary to use 1/2 PEX and 1/2 X 3/4 reducer PEX elbows just out of the manifold. (I had mentioned that 3/4" fact upon placing my order.)One of the 1" connections for the Return had slightly defective female threading, which I overcame by using a steel nipple (not having a 1" pipe tap to dress it with) to first run into the fitting.None the less, overall I am very well pleased with the value.
What size pex is used for the supply/return?
Read 1 answer
For a 2-branch model, 1/2" PEX is sufficient for supply/return as long as the hot water heating equipment (i.e. boiler) is nearby. There's more info on flow and pressure drop characteristics of PEX here: http://www.pexuniverse.com/pex-tubing-technical-specs

Can these be installed upside down. I.e, installed with pex going upward. Will the flow gauges still work?
Read 1 answer
The manifold can be installed upside down, but the flow meters may not function (provide proper flow reading) properly.

Do i need actuators on each zone valve? thanks.
Read 1 answer
Actuators are only needed when you want to control the water flow through the loop automatically, such as via a thermostat. In that case, you would need to get a zone control module (Taco ZVC) and a standard 24V heating thermostat. If all the manifold outlets are servicing a single zone (area with temperature controlled by a single thermostat), such as a bedroom, garage or other, you're better of using a single zone valve on the return line or a single circulator (Grundfos or Taco). There's no need for a separate actuator for each PEX manifold branch. If a single manifold services 2 or more zones, and you want automatic temperature control, actuators are needed for ea. branch (loop).

Would this 2-branch ss manifold system be appropriate for a room totaling 960 sq ft using 3/4 PEX? We will be using 7 baseboard fin tubes each about 8 ft long and two loops, both on the same zone.

SSM and BSM series radiant heating manifolds are best used with 3/8", 1/2" or 5/8" PEX. If your project has 3/4" copper tube baseboards, you could use 5/8" PEX instead of 3/4", as we do not have (nor does the manufacturer makes) the 3/4" PEX adapters for these manifolds.
