About this item

  • [5 Loop Radiant Heating Manifold]:FAHKNS underfloor heating manifold is made of high quality SUS304 stainless steel cold processed and molded, and the sealing element is EPDM rubber for a strong seal. The main pipe and inlet/outlet valves are 1" NPT thread, adapter 1/2", suitable for 12MM ID 16MM OD PERT PEXD and other underfloor heating pipes.
  • [Automatic Exhaust And Drain Valve]:The automatic exhaust and drain valve removes the air that exists inside the system during water injection and operation in a continuous and automatic manner, and the moisture-absorbing exhaust cap prevents accidental dripping and ensures the safety of system operation.
  • [Visual Flowmeter-Type Shut-Off Valve]:Inlet branch with visual flowmeter-type shut-off valve, can accurately adjust the amount of water in each circuit to 0-5 liters per minute, to prevent water grabbing by branch pipes, and effectively ensure the hydraulic balance of each circuit.
  • [Simple Installation]: Each part can be replaced and removed individually according to your actual needs, stainless steel body for long term use, large internal space, sufficient flow rate, widely used in radiant floor heating systems, but not for potable water applications.
  • [Fine Processing]: The main port is designed with extended threads for a stronger connection, with a depth of 18 mm.SUS 304 stainless steel, corrosion-resistant, non-rusting, long service life, brushed surface, durable, no matter how long you use it, the surface is as smooth as new.

We used this to heat a small 350 sq ft area with two zones. Was easy to integrate with other off the shelf items to complete the setup. The manifold felt hefty and well made. No issues when installing and is doing exactly what it was designed to do for the past month or so.
Always something to do

Final verdict first, this is a good quality manifold for the price that tested well. 4.4 stars.All threads are perfect.I like that this set includes isolation valves!All of the valves open and close smoothly but are also obviously tight, they all seal well.Connectors hold tight and well sealed. A tiny bit of silicone spray might help to not damage o-rings upon insertion.The plastic parts and temp gauges could be thicker and more durable, but are still very good and work perfectly well.The u-shaped hangers could also be a little more heavy and durable, but they also work perfectly well.All components work perfectly and flow adjustments are easy to set.Make sure that you or your installer knows what they are doing in order to properly prime the manifold to expel any air out of the system.I’m using this 2 loop manifold to retrofit a non-heated walkout basement.Final thought: I would order another one if I expand this hydronic system or if I install another one.

This is a fair amount more control over the water flow than a simple manifold. There are flow meters showing how much water is flowing into each loop of a zone - the more loops in a zone, the more flow meters to mess with. The flow through each loop can be balanced to match the other loops, creating even heating throughout an entire zone. This balancing is achieved on either the inlet valve to a loop, or the outlet valve, or both. This makes for a highly configurable manifold that has the ability to be adjusted for various parameters as desired.This particular unit has flow measurements in liters per minute. The inlet and outlet temperature gauges are in degrees celsius as well. Not a big deal to do a conversion and adjust to the metric numbers.This manifold comes with everything pictured. Ball valves, air bleeders, drain connections, mounting brackets - it's all there... All components have quality machining, and appear to be made to last a while without a lot of maintenance required.As for pricing, this manifold is comparable to other units from Chinese manufacturers on Amazon, but is a fair amount less than units from plumbing supply shops. My guess is it has to do with where it's been manufactured, and the labor costs involved.This manifold isn't going to get installed until summer/fall of 2024, so no actual in-use data until then. From all appearances, I'm not expecting to have any issues.
