Grundfos UPM3 A-Rated Single Room Underfloor Heating Mixture Pump Pack – 3kW with 7m Head Circulator

Upgrade your home with our compact single room mixture pump pack — the ideal plug-and-play control unit featuring the reliable Grundfos UPM3 FLEX AS 25-70 130 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 Grundfos UPM3 delivers best-in-class efficiency (EEI ≤0.20, up to 80% energy savings vs conventional pumps), quiet noise-free operation, and advanced digital control for optimal performance. Paired with the built-in thermostatic mixing valve, it 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.
