A complete TRV set for more flexible room heating

Designed to combine individual radiator control with a coordinated finish, this Chrome Derry Bold thermostatic valve set includes both the TRV and matching lockshield. Its angled layout suits the relevant pipe route, and the liquid sensing mechanism adjusts the valve as surrounding temperature changes.

Why choose these radiator valves?

  • Take more control of individual room comfort: Instead of leaving the radiator fully open, the TRV adjusts the flow of hot water as the surrounding room temperature changes.
  • 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.
  • Get the complete valve pair in one purchase: Supplying a matching lockshield alongside the TRV means both visible valve positions can be completed as one coordinated set.
  • Use a fitting designed around your pipe direction: Where pipework approaches a side-entry radiator from the floor, an angled valve provides the change in direction needed at the connection.
  • Adjust the radiator to suit how you use the room: Several thermostatic settings give you more flexibility than a simple manual on/off valve.
  • Benefit from automatic response to changing room temperature: Room-temperature changes are detected by the liquid sensor, allowing the valve to regulate flow automatically.
  • Make the valve set part of the radiator's overall look: A cleaner modern form helps the valve set feel coordinated with contemporary radiator designs. The Chrome colour with a polished & un-lacquered finish gives the visible valve set a considered decorative appearance.
  • Choose a valve set backed beyond installation: With a 3 years guarantee, the set comes with added reassurance for the years after 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.
