Stirling Bold - Black Thermostatic Radiator Valve & Installation Kit Angled 15mm (130mm version)

Room-by-room comfort with thermostatic radiator control

The Stirling Bold Black thermostatic radiator valve and matching lockshield give you room-by-room control over an individual radiator while keeping the installation visually coordinated. Its angled 15mm fitting and liquid sensor combine practical connection design with automatic thermostatic response as the room temperature changes.

Why choose these radiator valves?

• Set each room's warmth more independently: Thermostatic control lets this radiator react to the temperature of its own room rather than relying only on the main heating controls.
• Avoid heating a room more than you need: By reducing hot-water flow when the room is warm enough, the valve can help limit unnecessary heating in that space.
• Keep a layer of frost protection in reserve: A frost-protection setting helps reduce freezing risk by allowing some hot-water flow when the room temperature drops to a very low level.
• Simplify the purchase with both valves supplied: Both the thermostatic side and matching lockshield are included, simplifying the parts you need to source for the radiator.
• Use a fitting designed around your pipe direction: Angled valves suit common layouts where pipework rises from the floor to meet a side-entry radiator connection.
• Adjust the radiator to suit how you use the room: Multi-temperature control provides a choice of thermostatic settings rather than limiting the radiator to fully open or fully closed.
• Benefit from automatic response to changing room temperature: A liquid-filled sensor reacts as the room warms and cools, helping the valve adjust without constant manual intervention.
• Choose a finish that complements the installation: The modern valve shape keeps the installation looking clean and contemporary. The Black colour with a matt finish gives the visible valve set a considered decorative appearance.
• Buy with longer-term reassurance: The 3 years guarantee provides added reassurance for a product intended to remain part of the heating installation for years to come.
