1/2" PEX adapters are included by default. For other size adapters (free upgrade) make a note at checkout.

 

8-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.

 

SSM108 set is typical for radiant floor heating applications in areas with a total of 1800 - 2200 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 (8) flow meters and (8) 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 (8) manual balancing valves and (8) 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 vent 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.

 

(16) Compression-style adapters for 1/2" PEX tubing.

 

Applications:

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: 16 (8 on supply and 8 on return manifold);

Distance ON (On Center) between outlets: 2";

Overall height when installed: 14.5"

Overall width when installed (with shut-off valves): 22.75"

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 Testing Kit (SKU# TESTKIT).

8-branch Stainless Steel Radiant Heat Manifold Set w/ 1/2" PEX adapters has an average 5.0 out of 5 rating based on 2 user reviews.

8 Branch Radiant Manifold
By Nick Rummel (from Morton, IL) on 10/29/2012
Manifold is great quality, easy to install, plenty of room between nuts to tighten. Air eliminator is nice to have in that position. Temp gauges, although small, work great.

CAN YOU ADJUST THE FLOW ON EACH INDIVIDUAL LOOP WITH THIS MANIFOLD?
Read 1 answer
Yes, the flow can be adjusted for each branch individually by adjusting the manual balancing valves (white).

Lots of these manifolds being sold online do not come with the adapters for the 1/2" pex runs which you need to buy around 4-6$ each. You website implies that these are included (all 16) but never explicitly states this. So are they included? If so this is a far better deal.

All (16) PEX adapters are included. You can see this under the "List of components" and also in the product title "8-branch Stainless Steel Radiant Heat Manifold Set w/ 1/2" PEX adapters".

I have seen and understand your answer regarding turning the supply side manifold upside down due to the flow meters. Is there any reason I should not turn the return side upside down to solve 50% of my tubing issue since my tubing runs are all above the level of the manifold?

There's no restriction on installing the return manifold upside down. If that helps your installation, feel free to do so.

Can you mount these manifolds upside down and not affect the flow valve and meters?
Read 1 answer
We do not recommend installing the manifold upside down mainly for the reason that flow meters will accumulate debris and will start malfunctioning over time. A better option is either to install the manifold outside the boiler room above the PEX lines (in a wall, covered with an access panel) or to install the manifold in a normal position as shown on the product picture and then route PEX tubing to the sides and then upwards.

I have four runs of pex in my basement floor so assume I would need a four branch manifold for this section. I also have four runs of pex in my first floor. Will I need another 4 branch manifold for that floor and if so how ar they connected.
Read 1 answer
If you plan to have both floors as a single zone, controlled by a single thermostat, then a single 8-branch manifold (SSM108) is the right choice. If you plan to have the basement and first floor as separate zones, (2) SSM104 4-branch manifolds are a better choice, since they allow for independent control of each zone. A single 1" zone valve can be installed on manifold supply line right before the main shut-off. Basement and 1st floor zone valves are then wired to a zone control, such as Taco ZVC403 to zone 1 and 2 respectively. A single zone can be controlled with a 24V thermostat of your choice. You can refer to the ZVC403 manual for details.

Is there a reason that I would want to choose a stainless manifold over a brass manifold?
Read 1 answer
There's no particular reason except that the brass version has a somewhat more heavily built manifold body. Otherwise, all the components and specifications are the same.

Which side is supply one with flow meters
Read 1 answer
The supply manifold is always the one with flow meters and it is usually installed below the return manifold for easier air elimination.
