A Thermostatic Radiator Valve (TRV) automatically regulates the temperature of a room by controlling the flow of hot water into the radiator. A Lockshield valve is used to balance the heating system by setting a fixed flow rate for that radiator, and it is typically only adjusted during initial system balancing.
You need a corner valve if your radiator pipes enter the radiator from the wall or floor at a 90-degree angle relative to the radiator's connection. A straight valve is used when the pipework enters directly from the wall or floor in line with the radiator connection.
The 'Gunmetal' finish refers to a specific dark, metallic grey color with a brushed texture, offering a modern and sophisticated aesthetic often associated with industrial design.
Installation requires basic plumbing knowledge and draining the heating system. If you are not comfortable with these tasks, it is recommended to hire a qualified professional for safe and correct installation.
Specific warranty information is best obtained directly from the retailer or manufacturer's official documentation, as it can vary.
The TRV head typically has numbered settings (e.g., 1-5) corresponding to different temperatures. Lower numbers indicate lower temperatures (e.g., for frost protection), and higher numbers indicate higher temperatures. You will need to experiment to find the setting that corresponds to your desired room temperature.
The valve is expertly crafted from high-quality, durable brass.
Check if the TRV head is set to '0' or 'Frost' setting. Ensure the lockshield valve is fully open. Verify the radiator valve is correctly installed and the system has water pressure.
The TRV head might be faulty or jammed. Try gently tapping the pin underneath the head. If the issue persists, the TRV may need replacement. Ensure the lockshield is not fully open if it's causing excess flow.
A slight hiss can be normal as water flows. Persistent dripping may indicate a faulty seal within the valve or an incorrectly tightened connection. Check connections and consider replacing the valve if the noise is excessive or leaks occur.
The TRV head might be stiff due to disuse or debris. Gently try to work the pin underneath the head (with the system off and cool). If still stiff, remove the head and clean any visible debris. Ensure the head is reattached correctly.
