Frequently Asked Questions

Q: What thread size does this thermostatic radiator valve use?

A: This thermostatic radiator valve uses a standard M30 × 1.5mm thread, which is compatible with most modern radiator valve bodies. If your existing valve body uses a different thread size, an adapter may be required.

Q: Can this valve be used with underfloor / floor heating systems?

A: Yes, this valve is suitable for both traditional radiator systems and floor heating temperature control applications, provided the pipework connections are compatible with the M30 × 1.5mm fitting.

Q: How do I set and lock the temperature on this thermostatic radiator valve?

A: Simply rotate the control head to your desired temperature within the 6°C to 28°C range. The built-in temperature lock feature can then be engaged to prevent accidental changes — particularly useful in shared spaces, offices, or children's rooms.

Q: What is the maximum pressure this valve can handle?

A: The valve is rated for a maximum working pressure of 10 bar and a nominal pressure of 16 bar, making it suitable for standard domestic and light commercial central heating systems.
