This Wärmer System Underfloor Heating Manifold is designed for homeowners and professional installers seeking precise control over multiple heating zones. Its primary benefit is the ability to set individual temperatures for different areas, optimizing comfort and energy efficiency. A potential consideration is its 11-port capacity, which may be more than needed for smaller systems. Key features include individual zone control, 15mm pipe connections, main isolating ball valves, an automatic air vent, a pressure gauge, and a filling/drain off valve, all housed in a durable construction for reliable performance.

This manifold features 15mm pipe connections, which is a standard size for most underfloor heating systems.
This manifold itself does not have integrated thermostat connections. Thermostats would typically connect to the corresponding actuators on the manifold's zone valves, which then control water flow.
This manifold is specifically designed for hydronic underfloor heating systems and is not intended for potable hot water distribution.
While specific limits depend on the overall system design, manifolds like this are generally designed for standard heating system temperatures (up to ~70°C) and pressures (typically 1-3 bar).
It is recommended to check the system pressure gauge regularly, especially after initial installation or maintenance, and at least seasonally, to ensure it remains within the manufacturer's recommended range.
While straightforward for experienced plumbers, installation involves plumbing connections and system setup. For optimal performance and safety, professional installation by a qualified heating engineer is recommended.
The main isolating ball valves allow you to shut off water flow to the entire manifold or individual zones (if intermediate valves are present on the ports) for maintenance, repairs, or system draining without affecting other parts of your heating system.
Check that the corresponding port on the manifold is open and that there are no blockages in the pipework. Ensure the automatic air vent is functioning correctly to release trapped air.
Check the pressure gauge. If low, the system may need refilling via the filling/drain off valve. If high, air may need to be bled from the system, or there may be an issue with the expansion vessel. Consult a professional if unsure.
Turn off the heating system and isolate the manifold using the ball valves if possible. Gently tighten the leaking connection. If the leak persists, the fitting may need to be replaced or resealed.
This may indicate a persistent air leak in the system or a faulty air vent. Try closing and reopening the associated ball valve to reset it. If the sound continues, the air vent may need replacement.
Setup: Installation typically involves mounting the manifold securely to a wall, connecting the primary flow and return pipes from the boiler or heat source to the manifold's inlet and outlet, and then connecting the individual underfloor heating circuits to the respective ports. Ensure all connections are tight to prevent leaks. The automatic air vent and filling/drain off valve should be positioned at the appropriate ends of the manifold as per the installation manual.
Compatibility: This manifold is designed for use with standard hydronic (water-based) underfloor heating systems. The 15mm pipe connections are compatible with most common underfloor heating pipes. It is crucial to ensure compatibility with your existing or planned boiler and pump system, particularly regarding flow rates and pressure requirements.
Care: Periodically check the pressure gauge to ensure it is within the recommended operating range. Listen for any unusual noises that might indicate air in the system. The automatic air vent should function continuously, but it's good practice to manually bleed any remaining air via the vent or the drain off valve during initial system filling or annual maintenance. Clean the exterior of the manifold with a damp cloth; avoid abrasive cleaners.
