The user can then rotate the head to the desired setting to regulate the heat output of the radiator based on the ambient room temperature.
What to consider before purchase
Verify that your radiator piping matches the 1/2 inch and 3/4 inch EK connection requirements.
Ensure the valve is compatible with your existing thermostatic head model.
Check the system pressure and temperature limits of your current heating installation.
Usage recommendations
Regularly inspect the valve for any signs of leakage or buildup. It is recommended to keep the thermostatic head clean and free from obstructions to ensure accurate temperature sensing and optimal energy efficiency throughout the heating season.
