Wilo Para A-Rated Single Room Underfloor Heating Mixture Pump Pack – 3kW with 6m Head Circulator

Upgrade your home with our compact single room mixture pump pack — the ideal plug-and-play control unit featuring the reliable Wilo Para 25/6-43/SCU high-efficiency A-rated circulator pump.

Perfect for adding water underfloor heating to bathrooms, extensions, conservatories, or any small space up to 20m², it connects straight to your existing radiator, boiler, or central heating system with zero major disruption.

The integrated Wilo Para sets the standard for energy-saving performance (EEI ≤0.20, low power 3–43W), quiet operation, and advanced self-control, while the built-in thermostatic mixing valve auto-blends and regulates flow temperature for safe, even heat distribution without floor overheating.

Coverage & Performance

• Up to 20m² at 200mm pipe centres (ideal for standard small rooms).
• Up to 15m² at 150mm pipe centres (for higher heat output needs).
• 3kW heat output for fast warm-up and reliable comfort.

Get precise zoned heating where full-house underfloor isn’t practical or budget-friendly.
