Hydronic Radiant Heat Control Panel 2 Zone | Warming Systems
This preassembled panel from Warming Systems is presented as a more feature-complete option for two-zone control, and the listing highlights compatibility with glycol systems and boilers with internal circulation pumps.
Listed features include: includes expansion tank, pumps, air separator, compatibility with glycol, easy flush/fill access, and professional manufacturing with name-brand components. The seller requests a phone number after purchase for delivery coordination.
Use cases: Suited for installations where system priming, air separation, and expansion capacity are needed out of the box. The panel is intended to be connected to a boiler or water heater and supports 1–4 zones with appropriate variants.
Compatibility and considerations: Verify whether the boiler already includes a circulator. If not, an additional circulation pump may be required. Check copper connection sizes (listed as 1″ boiler connections and 3/4″ manifold connections) and ensure mounting space and service access.
WiseWater 110V Circulation Pump, 130W 13 GPM | AB
Call 888-896-7031 for Free Local HVAC Quotes – Compare and Save Today!
The WiseWater circulator is a compact electric pump designed for hydronic applications including boilers, solar heaters, and radiant floor systems. It offers manual three-speed adjustment to balance flow and head needs.
Listed features: three-speed (55/90/130W), max flow 13 GPM, head range up to 24 ft, standard 1″ NPT flange with included gaskets and fasteners, and maintenance-free design without mechanical seals to replace.
Use cases: Applicable where a dedicated circulator pump is needed for zone piping or as a boiler feed circulator. Three-speed control allows installers to optimize flow for system head and heat output without external variable-speed drives.
Compatibility and considerations: Match pump max head to system pressure drop and loop length. Use pump speed to balance heat delivery across loops; oversized flow increases boiler short-cycling risk. Verify electrical supply (110V) and flange size for plumbing compatibility.
EasyFloor Aluminum Heat Plates For Hydronic Radiant Floor
Aluminum heat plates improve thermal transfer between PEX tubing and finished floors, reducing thermal lag and improving system efficiency. These plates are optimized for use with grid modules and distribution panels.
Listed features: maximizes heat transfer, optimized for EasyFloor Grid and Floorheat panels, and designed to reduce heat loss and improve energy efficiency. The plates increase conduction from tubing to the flooring surface for faster response.
Use cases: Best for retrofit or new construction installations where thin-slab or wood floor assemblies benefit from enhanced conduction. Heat plates are commonly used in conjunction with staple-up or grid systems where tubing is near the floor surface.
Compatibility and considerations: Confirm plate spacing for your chosen PEX diameter and loop layout. Aluminum plates change acoustic and expansion behavior; ensure proper isolation where dissimilar metals contact structural elements to prevent galvanic issues.
Happybuy 3/4″ X 500Ft PEX Tubing Oxygen-Barrier | Happybuy
This 3/4″ oxygen-barrier PEX roll is intended for hydronic floor heating applications where corrosion prevention and long-term service life of metal components are priorities. The roll length supports larger loop layouts or multiple zones.
Listed features include: EVOH oxygen barrier to reduce oxygen ingress and metal corrosion, 3/4″ nominal diameter, 500 ft total length, smooth inner pipe for anti-scaling, and compatibility with crimp, cinch, press, and compression systems.
Use cases: Recommended for primary tubing runs in radiant floor systems, especially where steel or copper manifolds and boilers are used. The oxygen barrier extends system life by limiting oxidation in closed-loop systems.
Compatibility and considerations: Match tubing size to manifold adapters and flow requirements. 3/4″ tubing supports higher flow and longer loops but requires correspondingly sized manifolds, fittings, and installation clamps. Verify local plumbing codes and connection methods.
ABST PEX Manifold, 8 Loop Stainless Steel Manifold Kit
This 8-loop stainless steel manifold kit is designed to distribute heated water evenly across multiple radiant floor loops. It includes adapters and mounting hardware to simplify installation and support up to 1.32 GPM per flow meter.
Listed features: 8 loops, 1″ NPT supply/return shut-off ball valves, high-flow meters, 1/2″ adapters included (16 pcs), 304 stainless steel construction, pressure-tested and pre-assembled mounting bracket.
Use cases: Appropriate for multi-zone hydronic floor systems in residential applications where loop balancing, shut-off capability, and clear flow metering are required. Stainless construction improves corrosion resistance.
Compatibility and considerations: Confirm PEX size compatibility (manifold includes 1/2″ adapters) and mounting location for service access. Use flow meters to balance loop flow and ensure even heat distribution. Stainless manifolds are heavier than brass and may require more robust mounting.
Buying Guide: Choosing Hydronic Radiant Heater Components
System Type And Scope
Decide whether you need a full preassembled distribution panel or individual components. Preassembled panels reduce wiring and plumbing errors for small to medium installations, while separate components offer customization for complex systems.
Boiler And Circulator Compatibility
Match the panel plumbing sizes and pump head to your boiler output. Confirm whether the boiler has an internal circulator; some preassembled panels assume boiler-side pumping. Choose a pump with sufficient head for loop length and elevation changes.
Tubing Diameter And Loop Length
Loop length and tubing diameter directly affect flow rate and heat output. 1/2″ PEX is common for short loops; 3/4″ supports longer runs and higher flow but requires compatible manifolds and fittings. Use manufacturer charts to size loop lengths.
Oxygen Barrier And Corrosion Control
Choose oxygen-barrier PEX (EVOH) in closed-loop systems to protect metal components. An air separator and proper expansion tank also help maintain system longevity by removing entrained air and controlling pressure changes.
Heat Transfer Components
Heat plates and aluminum transfer elements improve response time and uniformity in floor systems with thin floor assemblies. Consider plate spacing, floor construction, and thermal resistance to optimize performance.
Manifolds And Balancing
Manifolds with integrated flow meters and shutoffs make balancing loops and servicing easier. Stainless steel manifolds provide corrosion resistance; brass manifolds offer different cost and weight characteristics. Verify adapter sizes for your PEX.
Controls And Zoning
Plan zones by room use and control requirements. Thermostats, wiring centers, and isolation valves influence panel layout. Preassembled panels simplify thermostat connections but confirm the number of supported zones and control wiring conventions.
Electrical And Pump Selection
Ensure pump voltage matches site electrical supply. Variable-speed pumps offer better efficiency for changing loads, while three-speed pumps provide manual balancing without additional controls. Consider noise ratings for indoor installations.
Installation And Service Access
Allow clearance for filling, flushing, and servicing components. Preassembled panels reduce field assembly time but still require access for valves, expansion vessels, and air separators. Plan mounting locations with maintenance in mind.
Energy Efficiency And Controls Integration
Integrate outdoor reset controls and programmable thermostats to improve efficiency. System-level controls that modulate flow or boiler temperature reduce cycling and improve comfort while saving energy.
Code, Warranty, And Support
Verify local plumbing and mechanical codes for closed-loop hydronic systems. Check manufacturer warranties, component brands used in preassembled panels, and available technical support for system design questions.

Comparison Perspectives
- Preassembled Panel vs. Custom Components: Panels save installation time and reduce error risk; custom builds allow tailored performance and phased upgrades.
- Pump Types: Variable-speed pumps optimize efficiency across conditions; multispeed pumps allow manual tuning at lower cost.
- PEX Size Tradeoffs: Larger PEX supports longer loops but adds material cost and requires appropriate manifolds; smaller PEX is easier to rout and cheaper but limits loop length.
- Manifold Materials: Stainless offers higher corrosion resistance; brass is common and cost-effective. Choose based on system water chemistry and longevity priorities.
