This Angled Thermostatic Radiator Valve (TRV) in Brushed Silver Nickel with a natural wood top is designed for homeowners seeking a refined upgrade for traditional radiators. It offers precise temperature control and frost protection, ensuring comfort and energy efficiency. A key caveat is that the accompanying pipe sleeves must be installed before the valves and radiator.

A TRV is a device fitted to a radiator that allows you to control the temperature of an individual room. It automatically adjusts the flow of hot water into the radiator based on the room's ambient temperature.
An angled TRV is designed for installations where the pipework connects to the radiator at an angle, typically rising vertically from the floor and then turning to connect to the radiator valve.
The valve has a numbered dial (typically 0-5). Higher numbers correspond to higher desired room temperatures. Setting '5' is usually fully open, while '0' or '*)' indicates frost protection or shut-off.
Frost protection ensures that if the room temperature drops to around 5-8°C, the valve will open slightly to allow a small amount of hot water to circulate, preventing your pipes and radiator from freezing and potentially bursting during very cold weather.
This TRV is compatible with radiators featuring a 1/2" BSP valve connection and requires 15mm pipework. It is designed for angled pipe configurations.
The pipe sleeves are optional aesthetic components that cover the pipework. If you choose to use them, they must be installed onto the pipework *before* the TRV and radiator are fitted.
UK Radiators typically offers a 3-year warranty on their thermostatic radiator valves.
Check if the TRV head is fully open (set to maximum or '5'). Ensure the pin inside the valve body can move freely; if stuck, gently try to free it with pliers (ensure system is drained and off first). Verify the lockshield valve is open.
The TRV pin may be stuck in the open position. Turn off the heating, drain the system, and carefully try to free the pin. If it remains stuck, the TRV may need replacement.
Ensure all connections are tightened correctly. If leaking from the 1/2" BSP fitting, check the radiator's valve connection or the thread sealant used. If leaking from the pipe connection, check compression fittings or solder joints.
Allow the system time to stabilize after adjusting the TRV setting. Ensure the TRV is not placed in direct sunlight or next to a heat source, which can affect its sensor readings. Confirm the desired room temperature is achievable by the heating system.
