Manual water-flow control with a coordinated anthracite finish

Designed for simple, hands-on radiator control, this Round valve pair in matt Anthracite lets you manually adjust the amount of hot water entering the radiator. Unlike a TRV, it does not respond automatically as room temperature changes, making it a straightforward choice where manual control is preferred.

Why choose these radiator valves?

  • Adjust the radiator without thermostatic regulation: You control the radiator by physically adjusting the valve position, which changes how freely hot water can enter it.
  • Use a simple alternative to automatic temperature control: There is no automatic room-temperature response: once set, the valve continues to allow the selected level of flow until you manually change it.
  • Get both radiator valves in one set: A matching pair of manual valves is supplied, giving you the valves needed for both sides of the radiator in one coordinated set.
  • Match the valve shape to your pipe route: Where the pipework and radiator connection line up directly, the straight format avoids adding an unnecessary turn to the pipe route.
  • Get the correct pipe-side connection: The supplied reducers adapt the valve set for 8mm microbore pipework, giving this version a connection suited to matching 8mm pipes.
  • Carry the finish through to the visible fittings: The Anthracite finish and rounded valve shape turn a necessary radiator fitting into a considered part of the installation rather than leaving the connection visually unfinished.
  • Get durable brass at the radiator connection: The valves are made from brass, providing durable construction beneath the visible finish.
  • Get extra peace of mind after fitting: A 5 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.
