Low Temperature Blending Valve (20–55°C) & Wilo Pump

Introduction to the low temperature blending valve with Wilo pump The low temperature blending valve with Wilo pump is a high-performance, pre-assembled solution for underfloor heating systems.

This unit combines a precise thermostatic mixing valve with a reliable A-rated Wilo circulation pump (such as the popular Para series models like Para 25/6 or similar SCU variants). As a result, it delivers safe mixed flow temperatures from 20°C to 55°C.

Moreover, it provides excellent scald protection, safeguards UFH pipes, screeds, and floor coverings from overheating, ensures uniform heat distribution, and fully complies with BS EN 1264 warm-up procedures.

Therefore, it’s an ideal choice for multi-zone domestic installations, offering low energy consumption and quiet, dependable operation.

Key Features

• Scald-safe temperature control to safeguard UFH pipes and coverings
• Precise ±3°C stability across the 20–55°C range
• Low 20°C setting meets BS EN 1264 warm-up requirements
• High-flow 3.4 kvs for better circulation and lower pressure drops
• Compact design with minimal space and clearance needs
• Integrated temperature gauge on mixed flow (standard)
• Quick manifold connection via spinning nuts
• Built-in check valve for fast UFH manifold filling
• Self-sealing connections to reduce leak risks
• Wilo A-rated circulation pump – high-efficiency EC motor (EEI ≤ 0.20–0.23), low power draw (typically 3–50W), variable/constant pressure modes (Δp-v, Δp-c), constant speed options, max head around 6–7m, max flow up to ~3 m³/h, 25mm threaded connections, quiet operation, IP44 rated, integrated protection, and significant energy savings (up to 80% vs traditional pumps) for optimised UFH performance

Installation Flexibility Furthermore, the unit is fully reversible for left- or right-handed setup (top or side entry). In addition, you can optionally replace the gauge with a high-limit flow temperature sensor. Finally, the Wilo pump includes intuitive controls (e.g., Green Button Technology or similar) for easy mode and speed adjustment to perfectly match your system’s requirements.

UK Quality & Support Moreover, every unit is fully assembled and pressure-tested in the UK, backed by dedicated local technical support. Consequently, the robust build and efficient Wilo pump help reduce energy bills, minimise maintenance, and extend system lifespan – making it a sustainable option for eco-friendly home heating.
