Underfloor Heating Blending Valve with Bastion 7.5m Pump

This underfloor heating blending valve with Bastion 7.5m pump combines a compact thermostatic blending valve and high-efficiency Bastion A-rated circulator pump for precise, safe temperature control in water underfloor heating systems.

The fully assembled left-hand unit features G1 male swivel flat seal unions for direct, bracket-free manifold connection — no drilling or extra fixings required.

The thermostatic blending valve adjusts flow temperature from 35–65°C (factory set at 45°C) via a simple knob: clockwise to increase, anticlockwise to decrease. This ensures even, comfortable floor warmth without overheating risks, while the upgraded Bastion 7.5m pump delivers reliable, higher-head circulation for more versatile system designs with ultra-low energy use.
