Hydronic Radiant Heat Control Panel 2-Zone

The Hydronic Radiant Heat Control Panel 2-Zone is a pre-assembled heating panel designed for radiant floor systems. It includes a high-efficiency pump and essential components such as an expansion tank and air separator, ready for connection to a boiler or water heater. The panel allows control of 1–4 heating zones and is compatible with glycol-based mixtures, supporting easier future service and a clean, organized installation. Its USA-made construction emphasizes quality and warranty-backed performance. This panel is ideal for homeowners who want a streamlined, professional-looking solution with room for expansion as needs grow.
Key features include: pre-assembled, standard-brand components, simple flushing/filling, 1″ copper boiler connections, and ¾” manifold supply/return connections. It’s designed to work with standard boilers or water heaters with an internal circulation pump, making it adaptable to existing systems. This panel can simplify retrofits and new installs while offering robust support from the manufacturer’s engineering team.
Hydronic Radiant Heat Control Panel – 1 Zone

This 1-zone pre-assembled hydronic heating panel provides a reliable distribution point for radiant floors and small-to-medium spaces. It ships with an efficient layout that minimizes installation time and helps fit typical interior constraints. The panel’s compact footprint supports clean integration into living spaces, while its design emphasizes energy efficiency and ease of service. It is particularly suited for homeowners building new or upgrading an isolated radiant zone without the complexity of a full multi-zone manifold.
Highlights cover ease of installation, dependable energy performance, and a visually unobtrusive setup that blends with modern interiors. Although it focuses on a single zone, its proven reliability makes it a solid base option for future expansion if needed later on.
Hydronic Radiant Heat Control Panel – 4 Zone

The 4-zone version expands the same pre-assembled approach to larger homes or zones with more complex layouts. It provides multiple independent circuits for efficient, even heat distribution across different areas. This panel aims to reduce installation time by delivering a complete, ready-to-connect solution with durable components and straightforward plumbing connections. The design emphasizes both performance and flexibility, helping installers tailor radiant heating to varied floor plans and usage patterns.
Features include the same sturdy build quality as the 1-zone model, with added zone control capacity. It’s suitable for households seeking scalable radiant floor heating that can grow with their remodeling or new construction projects. As with other Floorheat panels, it focuses on reliability, ease of service, and compatibility with typical hydronic systems.
AB 110V 130W 13 GPM Hot Water Recirculating Pump

This 110V 130W recirculating pump is designed for hydronic and radiant heating applications, supporting up to 13 GPM with three speed settings. It includes a 1″ FNPT flange and integrated fittings for easier installation. The pump emphasizes energy efficiency and quiet operation while delivering hot water quickly to taps or radiant circuits. The three-speed control lets installers adjust flow according to system demand, helping to reduce waste and improve comfort in cold-weather use.
Notable aspects include maintenance-free operation without mechanical seals to replace and a straightforward connection process that can lower labor costs. Its compact size and flexible mounting make it a practical choice for integration with pre-assembled panels or standalone hydronic loops in radiant floor projects.
ABST PEX Manifold, 3 Loop Stainless Steel

The ABST PEX Manifold is a three-loop stainless steel distribution manifold designed for floor radiant heating. It includes 1/2″ adapters, 1″ NPT supply and return shut-off valves, and a high-flow meter for monitoring each loop. Stainless steel construction offers corrosion resistance and durability, while pre-assembly and mounting brackets simplify installation. This manifold supports balanced flow to multiple zones, helping maintain consistent temperatures across different rooms or areas requiring radiant heat distribution.
Key benefits include robust heat transfer efficiency, easy on-wall mounting, and pre-assembly that reduces field labor. The stainless steel build contributes to long-term reliability in residential radiant floor projects, making this manifold a favorable option for multi-zone configurations needing precise control and dependable performance.
Buying Guide: Key Purchase Considerations
When selecting a radiant floor heating system powered by water, consider the following factors to ensure a good fit for your home and budget:
- System scale and zoning: Determine how many zones you need and whether you want a single-zone, multi-zone, or expandable panel. Multi-zone panels offer flexibility for larger homes or diverse room uses.
- Ease of installation: Pre-assembled panels reduce field plumbing time and potential leaks. Look for panels with standard valve sizes (1″ and 3/4″ copper connections) and clear labeling.
- Compatibility: Check compatibility with your boiler or water heater and whether glycol compatibility is important for freeze protection or performance in mixed-use climates.
- Materials and durability: Stainless steel manifolds and corrosion-resistant components can improve longevity in hydronic systems, especially in homes with hard water or aggressive water chemistry.
- Flow management: Features like built-in flow meters and adjustable pump speeds help balance the system and optimize heat distribution across zones.
- Maintenance and service: Choose products from brands with strong support and documentation. Pre-assembled units can simplify future servicing and expansion.
- Noise and energy use: Evaluate pump efficiency, noise levels, and the system’s overall heat loss. Efficient pumps with adjustable speeds can reduce energy consumption.
- Space and aesthetics: Consider wall or cabinet space for panels and manifolds and how the installation will look in living areas or utility rooms.
For homeowners upgrading an existing home, a step-by-step approach typically includes verifying boiler compatibility, planning zone layouts, selecting a suitable pre-assembled panel or manifold, and coordinating with a qualified installer to ensure proper flushing, wiring, and air removal. For new builds, focus on integrating panels into the mechanical room layout and aligning with floor finishing timelines to achieve a smooth installation.
