What it is
The Warmflow 1621 is a mixer valve used on Warmflow oil combi boilers. It blends the hot and cold water supplies within the appliance to deliver a controlled domestic hot water temperature at the outlet. It is a serviceable component within the boiler's hot water circuit.
Signs this part needs replacing
- Domestic hot water temperature fluctuates or cannot be held steady at the tap
- The valve spindle is stiff, seized or will not adjust
- Water weeping from the valve body or spindle gland
- Scale or debris build-up inside the valve causing restricted flow
- Hot water runs consistently too hot or too cold regardless of setting
Before you order
- Confirm your appliance is a Warmflow oil combi model
- Check the part number on the existing valve against 1621
- Inspect the valve connections and surrounding pipework for damage before removal
- Verify the fault lies with the mixer valve rather than the boiler's temperature controls
