4. Setup and Installation
Proper installation is crucial for the optimal performance and longevity of your EMKE thermostatic valve. It is highly recommended that installation be carried out by a certified heating engineer.
Pre-Installation Checks:
- Ensure the heating system is completely drained and cold before beginning installation.
- Verify that the valve type (corner or passage) matches your pipework configuration.
- Check all components for any signs of damage before installation.
Installation Steps:
- Identify the flow and return pipes of your radiator/towel dryer.
- Attach the valve body to the radiator/towel dryer connections, ensuring a secure and leak-free fit. Use appropriate sealing materials if necessary.
- Connect the system pipes to the valve body. The valve is designed for both corner and passage configurations, accommodating pipes from the wall or floor.
- Once the valve body is securely installed, attach the thermostatic head by aligning it and tightening the connection.
- Slowly refill the heating system, bleeding air as necessary, and check for any leaks at all connection points.
Configuration Examples:
The EMKE valve supports various pipe configurations, as illustrated below:

5. Operating Instructions
The thermostatic head allows you to easily adjust the temperature output of your radiator or towel dryer.
Adjusting the Temperature:
- The thermostat head features 7 adjustable gears, indicated by numbers or symbols on the dial.
- Rotate the thermostat head to the desired setting. Higher numbers typically correspond to higher temperatures.
- The valve will automatically regulate the flow of hot water to the radiator to maintain the set temperature in the room.
Temperature Settings Guide:
The following table provides an approximate guide for the temperature settings:
Figure 5.1: Thermostat setting scale with approximate temperature ranges. Note that actual room temperature may vary based on insulation, external factors, and radiator size.
| Setting | Approximate Temperature |
|---|---|
| * (Frost Protection) | 7°C |
| 1 | 12°C |
| 2 | 14°C |
| 3 | 20°C |
| 4 | 24°C |
| 5 | 28°C |
6. Maintenance
The EMKE thermostatic valve is designed for minimal maintenance. Regular checks can help ensure its long-term performance.
Cleaning:
- Wipe the chrome surface with a soft, damp cloth.
- Do not use abrasive cleaners, solvents, or harsh chemicals, as these can damage the finish.
Periodic Checks:
- Periodically inspect the valve and connections for any signs of leaks. Address any leaks immediately.
- Ensure the thermostatic head rotates smoothly and the temperature settings are responsive.
- During periods of non-use (e.g., summer), it is advisable to set the thermostat to its maximum setting for a short period once a month to prevent the valve pin from sticking.
7. Troubleshooting
If you experience issues with your EMKE thermostatic valve, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Radiator not heating up (or only partially) | Valve pin stuck; Air in the system; Thermostat set too low; System pressure too low. | Remove thermostatic head and gently push the pin to free it; Bleed the radiator; Increase thermostat setting; Check system pressure and refill if necessary. |
| Radiator too hot (cannot regulate temperature) | Thermostat head not properly seated; Valve pin stuck open. | Ensure thermostatic head is securely attached; Remove head and check if pin is stuck open, gently push to free. |
| Water leaking from valve connections | Loose connections; Damaged seals/gaskets. | Tighten connections (do not overtighten); Replace damaged seals/gaskets. If leaks persist, contact a professional. |
| Thermostat head difficult to turn | Internal mechanism stiff; Dirt accumulation. | Gently try to turn it back and forth; Clean around the head. If still stiff, consider professional inspection. |
If the problem persists after attempting these solutions, please contact a qualified heating engineer or EMKE customer support for assistance.
