The Heart of Your Warmup Water Underfloor Heating System

The S3 Manifold ensures operational precision and utilises top of the range components for long-lasting, best-in-class performance. It is constructed from a single piece of 304-grade, laser-etched Stainless Steel for high corrosion resistance with no welds that might corrode and leak over time and provides control for up to 12 heat zones.

The Manifold’s Taconova flow meters improve accuracy and reliability for faster commissioning with lock rings to prevent tampering with the commissioned settings and memory rings that enable the valves to be closed and re-set quickly and confidently during commissioning or maintenance.

The Thermomanometer (combined Pressure and Temperature Gauge) on the flow arm facilitates pressure testing of multiple manifolds simultaneously and allows even easier operational checks. And the Manifold’s standard 3/4″ Eurocones make it compatible with a wider range of heating pipes and fittings. Warmup’s S3 Mixing Unit, Actuator, Isolation Valves and In-Wall Manifold Cabinet are available separately.
