Low Temperature Blending Valve (20–55°C) with Bastion 7.5m Pump – Scald-Safe UFH Control

The low temperature blending valve with Bastion 7.5m pump provides a complete, high-performance solution for underfloor heating systems. This pre-assembled unit integrates a precise thermostatic mixing valve with the powerful Bastion A-rated circulation pump, delivering safe mixed flow temperatures from 20°C to 55°C. It ensures scald protection, safeguards UFH pipes, screeds, and floor coverings from overheating, promotes even heat distribution, and complies with BS EN 1264 warm-up procedures. Perfect for multi-zone domestic installations or systems requiring higher head pressure, it delivers energy-efficient, reliable performance for modern heating setups.

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
• Bastion 7.5m A-rated circulation pump – energy-efficient (5–39W low power draw), intelligent modes (auto-adapt, constant/proportional pressure, PWM), push-button control, 7.5 metre max head, max flow up to 3.0–3.5 m³/h, 25mm (G 1½”) connections, 130mm port-to-port length, quiet operation (<42dB), IP44 rated, thermal protection, and ideal for demanding UFH or central heating circulation

Installation Flexibility

• Fully reversible for left- or right-handed setup (top or side entry)
• Optional: replace gauge with high-limit flow temperature sensor
• Pump offers easy speed/mode selection for optimised performance across different system requirements

UK Quality & Support Fully assembled and pressure-tested in the UK, with dedicated local technical support. The robust build and efficient Bastion 7.5m pump reduce energy consumption, minimise maintenance, and extend overall system lifespan – supporting sustainable, low-carbon home heating.
