Overview


The Manifold Basic Model is a reliable, cost-effective solution designed for distributing heating fluid in residential hydronic systems, ideal for single-family homes and small commercial spaces. Engineered with essential control features and durable steel construction, this manifold ensures balanced flow and easy installation, serving as the foundational component for efficient radiant floor heating and radiator systems. Its straightforward design and universal compatibility make it a preferred choice for contractors and DIY enthusiasts seeking a dependable hydronic solution.


Features


Core Hydronic Performance:

Constructed from seamless Q235B steel (50x50x2mm supply header, 50x80x2mm return header), supporting working pressure up to 8 bar and fluid temperature 100°C, suitable for low-temperature (35-55°C) underfloor heating and radiator setups.

2 supply + 2 return ports (DN25, NPT threads), compatible with PEX, copper, and steel pipes, offering total flow capacity 20-80 L/min (10-40 L/min per port) for zones up to 400m².

Essential Control Functionality:

Manual balancing valves (30-100% flow regulation) with quarter-turn handles for basic zone control, plus an integrated air vent (1/4" NPT) to eliminate air locks and a pressure gauge port for system monitoring.

Straightforward design with minimal pressure drop (≤1 bar at rated flow), reducing energy loss and ensuring consistent heat distribution.

Easy Installation:

Pre-assembled with a 50x50mm steel mounting frame and labeled ports (supply/return arrows), cutting installation time by 40% compared to custom manifolds.

Lightweight (3.2kg) with universal mounting holes (150x150mm), fitting standard wall studs and utility room layouts without specialized tools.

Durability & Compliance:

Epoxy powder coating (100μm, RAL 9006) for corrosion resistance in residential environments (RH ≤75%), with galvanized internal surface minimizing mineral buildup by 25%.

Meets EN 1264-3 (underfloor heating) and ASME B16.3 (threaded fittings), ensuring safety and regulatory compliance in North America and Europe.


Application


Ideal for basic hydronic needs, this manifold excels in:

Single-Family Home Heating: Distributes heat to 2-4 zones (living areas, bedrooms) via underfloor tubing or radiators, with manual balancing for room-by-room comfort.

Small Commercial Spaces: Powers radiant floor heating in offices, clinics, and retail stores (≤500m²), compatible with boilers up to 80kW.

Renovation Projects: Retrofits older homes with existing heating systems, offering a cost-effective upgrade to zoned heating without major modifications.

DIY Hydronic Setups: Appeals to homeowners for garage or basement heating, with simple installation using standard plumbing tools.


FAQ


Q: Can this manifold handle both radiant floor and radiator systems?

A: Yes, designed for mixed systems, with flow capacity suitable for both low-temperature floor heating and high-temperature radiator circuits.

Q: What is the recommended pipe size for connections?

A: DN25 pipes (1" NPT) are optimal; reducers for smaller pipes (DN20/DN15) are available as optional accessories.

Q: Is professional balancing required after installation?

A: Basic balancing can be done manually using the quarter-turn valves; for complex systems, a flow meter is recommended for precision.
