Thermostatic Radiator Valves

Quality TRV Radiator Valves in All Orientations, Styles and Finishes For Your Home

Thermostatic radiator valves (also known as TRVs or TRV radiator valves) from Radiator Valves 4u allow for individual room temperature management that contributes to a more efficient heating system and potential savings on your energy bills. 

These TRV radiator valves automatically adjust the flow of hot water to the radiator based on the room's temperature. 

What is a Thermostatic Radiator Valve?

A TRV valve reduces the flow to lower the radiator’s heat output when the room reaches the desired temperature and increases the flow when the room temperature drops. This automated adjustment provides a balance between comfort and energy efficiency without manual intervention, making radiator TRV radiator valves a practical solution for managing heating in different areas of a home or building.

Thermostatic radiator valves provide automatic temperature control that manual radiator valves don’t. Simply set it to the desired temperature setting and the valve will do the rest! This keeps the room at a steady, comfortable temperature without wasting energy.

FREQUENTLY ASKED QUESTIONS

Questions from our beloved customers

  • How often should a TRV be replaced?
    While a good quality thermostat radiator valve is built to be reliable, they don’t last forever. On average, you should consider replacing your TRVs every 10 to 15 years. Over time, the internal mechanism can wear out, making them less responsive and efficient.
  • What does a thermostatic valve do on a radiator?
    A thermostatic valve’s job is to control the temperature of a single room. It does this by sensing the air temperature around it and automatically adjusting the amount of hot water that flows into the radiator. When the room reaches your desired temperature, the valve reduces the flow, and when it cools down, it opens up again.
  • How does a thermostatic radiator valve work?
    Inside the head of the valve is a small capsule containing a special wax or liquid that expands when it gets warmer and contracts when it gets cooler. This expansion and contraction moves a pin inside the valve body, which in turn opens or closes the valve to control the flow of water. It’s a clever, self-contained mechanical device that doesn't require any electricity.
  • Can you replace a TRV yourself?
    If you are a confident and experienced DIYer, then yes, it’s entirely possible to replace a TRV yourself. However, it usually involves draining your central heating system, which can be a messy job if not done correctly. If you have any doubts, we always recommend hiring a qualified plumber.
  • What setting should TRV be on in winter?
    For living areas, a setting of 3 or 4 is usually ideal, which corresponds to around 19−22∘C. For bedrooms, you might prefer a cooler setting of 2 or 3. In rooms you don’t use often, you can turn the TRV down to the frost protection setting to prevent pipes from freezing while saving maximum energy.
  • Do you have to drain the system to change the thermostatic radiator valve?
    In most cases, yes. To prevent a flood, you need to drain the central heating system down to a level below the radiator you are working on. Some professional plumbers have specialist pipe-freezing kits that can isolate a single radiator, but for most DIY installations, draining the system is necessary.
  • Do thermostatic radiator valves shut off completely?
    Yes, when the room reaches the temperature you’ve selected on the dial, the valve will close completely, stopping hot water from entering the radiator. The radiator will then cool down naturally. It will only open again when the room temperature drops below your set level.
  • How to adjust a thermostatic radiator valve?
    Adjusting a TRV is simple. Just turn the head of the valve to the desired number or symbol. The numbers usually range from 1 to 5. A lower number means a cooler room temperature, and a higher number means a warmer room temperature. Give it a little time to work after you make an adjustment.
  • Can you turn off a radiator without a thermostatic valve?
    Yes. Most radiators have two valves. If you don't have a TRV, you will have a manual valve (or wheelhead) which you can turn clockwise to shut it off. The second valve is called a lockshield valve, which is used to balance the system and shouldn't be adjusted regularly. A TRV simply gives you automatic temperature control rather than just a manual on/off function.
  • How long do TRV valves last?
    A good quality TRV, like those sold at Radiator Valves 4u, should last for 10-15 years or more. Their lifespan can be affected by factors like water quality and how often they are adjusted.
  • How to tell if a TRV is faulty?
    Common signs of a faulty TRV include: The radiator is always on full heat, no matter the setting. The radiator stays cold, even when the heating is on and the valve is turned up. The valve head is stuck and won’t turn. There are water leaks from the valve body. Sometimes, the internal pin can get stuck. Gently removing the head and carefully working the pin up and down with a pair of grips can fix this.
