Stirling Bold - Black Nickel Thermostatic Radiator Valve & Installation Kit Angled 15mm
Product code: 51118
Simplify the radiator installation with a coordinated valve and accessory set
Bring the control and finishing details of the radiator together with this Stirling Bold thermostatic installation kit. The set pairs a angled TRV and matching lockshield with coordinated pipe covers and the additional supplied connection components, reducing the number of separate accessories you need to choose.
Why choose this radiator installation kit?
- Reduce unnecessary heating once the room is comfortable: The TRV responds automatically to room temperature, giving you more individual control than relying only on the main heating controls.
- Complete both radiator valve positions in one set: The TRV and matching lockshield are included together, giving you both valve positions as one coordinated set.
- Give the exposed pipework a cleaner finish: The supplied pipe covers help hide the exposed pipe immediately around the radiator connection, keeping the finishing details visually consistent.
- Help the radiator heat properly after installation: With a bleed valve included, the radiator can be vented when needed to support effective hot-water circulation.
- Complete the unused radiator connection: A blanking plug is supplied to complete the radiator's unused connection without another separate purchase.
- Choose a fitting designed around your pipework: The angled layout is designed around pipework approaching a side-entry radiator from below.
- Give the radiator connection a consistent look: The contemporary valve design helps the installation feel coordinated rather than purely functional. The Black Nickel colour with a polished & lacquered finish gives the visible parts of the kit a consistent appearance.
- Buy with longer-term reassurance: A 3 years guarantee gives you longer-term reassurance beyond the initial installation.

Watts & BTUs (British Thermal Units) Explained
What is a Watt?
Watts are our main unit of energy/power in the UK, commonly associated with lightbulbs and Home Energy performance certificates (EPCs).
What is a BTU?
BTUs are the unit of measurement used to portray a radiators heat output and a rooms heating requirement. 1 Watt is equal to 3.41 BTUs.
Why are they important?
We buy radiators to heat our homes, right? So, we need a way of knowing if a radiator is powerful enough to heat the room that we are shopping for - Watts and BTUs provide us with a value that makes its easier to compare radiators and ultimately choose the right one for our heating requirement.
Need help figuring out how much heat your room needs?
Our fast and easy-to-use BTU calculator can help you:
- Work out a heating requirement value (in BTUs & Watts) for your room
- Show you in-stock radiator recommendations that can fulfil this heat requirement
Delta (Δ) Ratings Explained
What is a Delta (Δ) Rating?
When discussing heat outputs, the Delta rating is the difference between the temperature of the water inside the heating system and the desired temperature of the room.
What does the value represent?
In simple terms, this value is about heat loss. Heating a room only works, if the radiator output exceeds the heat loss of the room.
We use this calculation to make it easy to choose a radiator that will have a heat output that exceeds the heat loss of the room when connected to your heating system type.
If you don't know the room heat loss, you can use our calculator to find out.
What Delta Rating should I use?
- Δ50 = Gas or oil boiler with a flow temperature of around 75°C and a return temperature of around 65°C.
- Δ30 = Low temperature systems e.g heat pumps.
