Warmer System Underfloor Heating Mixing Blending Valve With Thermostatic Head - B&Q

The thermostatic actuator is adjustable from 20°C to 65°C.

The valve features standard 1” BSP connections.

It is compatible with manifolds featuring standard 210mm spacing. Always check your manifold's specifications before purchasing.

The package includes the mixing valve, thermostatic head, remote probe, temperature gauge, automatic air vent, and a supporting bracket.

Yes, it includes a built-in non-return valve to prevent backfilling and reduce water loss.

The mixing valve has an integrated flow rate control valve that allows for precise regulation. Refer to the installation manual for specific adjustment procedures.

The remote probe measures the temperature of the water returning from the underfloor heating system, allowing the thermostatic actuator to accurately control the blend of hot and cold water.

Adjust the thermostatic head to the desired temperature. Ensure the remote probe is correctly positioned and making good contact with the pipe. Check that the flow rate control is set appropriately.

Turn off the water supply. Check that all connections are tight and that appropriate sealing tape (e.g., PTFE tape) has been used on threaded fittings.

Ensure the flow rate is balanced across all zones using the integrated control valve. Check for any blockages in the underfloor heating pipes or manifold.

Check if the vent is blocked or if the system pressure is too low. Gently try to open the vent manually to check for airflow. Bleed the system if necessary.
