UFH Manifold Blending Valve Pump Pack 20–55°C with Grundfos UPM3 Auto

This underfloor heating blending valve pump pack comes with a Grundfos UPM3 Auto 25-70 130 pump, which uses AUTOADAPT to set itself to the system. It suits installers who want the pump to adjust itself without tuning on commissioning day. The thermostatic valve mixes primary flow with return water to hold the floor at 20–55°C, and the whole unit bolts onto the manifold.

Why installers use it

• Self-adjusting pump: AUTOADAPT, plus proportional pressure, constant pressure and constant curve settings.
• Up to 7m head: from the Grundfos UPM3 Auto 25-70.
• Low-temperature ready: 20–55°C suits heat pumps and boilers.
• Arrives pre-assembled and tested: ready to bolt to the manifold.

Questions

Does the blending valve need wiring?
No. It's a thermostatic wax-capsule valve, so only the pump needs power.

Auto or Flex: which Grundfos pack?
Choose the Auto if you want the pump to set itself. Choose the Blending Valve Pump Pack with Grundfos UPM3 Flex if your heat source will control the pump by PWM.
