Radiator Valves

Radiator valves are a vital part of any heating system, helping you maintain comfort and efficiency at home. With options such as thermostatic radiator valves (TRVs), you can easily control the temperature of each radiator individually for a tailored heating experience.

Types of radiator valves

  • Straight Radiator Valves: Ideal for pipework that comes directly from the floor. These valves connect in a straight line, offering a neat and practical finish.
  • Angled Radiator Valves: The most common choice, angled valves connect at 90 degrees to help conceal pipework for a tidy look.
  • Corner Radiator Valves: A stylish option where the valve faces inward toward the wall, creating a discreet appearance.
  • Black Radiator Valves: A bold, contemporary choice that pairs perfectly with modern interiors and contrasts beautifully with lighter radiators.

    • Maintaining your radiator valves

    To keep your radiator valves efficient and long-lasting, regular maintenance is key. Using a radiator bleed valve helps release trapped air, ensuring your heating system runs smoothly and avoids cold spots.

    Why choose thermostatic radiator valves (TRVs)?

    Thermostatic radiator valves automatically regulate hot water flow based on room temperature. This maintains consistent comfort while reducing energy waste, preventing overheating, and lowering energy costs.

    Whether you need angled radiator valves, corner radiator valves, or advanced TRVs, our expert team can help you make the right choice. Visit your local Howarth branch for tailored advice or explore our full range online.

    Control your home’s heating with confidence and style using high-quality radiator valves from Howarth.

Frequently Asked Questions

How do I change a radiator valve?
To change a radiator valve, you will need to first switch off the heating and water system, and then locate the drain off. After that, you will need to remove the old radiator valve to be able to fit the new radiator valve. That is when you can turn the mains water back on, to be able to finish by bleeding the radiator.
How do thermostatic radiator valves work?
Thermostatic valve head goes on top of the valve body, and then as the room temperature changes, the valve head expands, adjusting a pin in the valve body so that it opens or closes.
What are the two valves on a radiator for?
One of the valves accounts for hot water that enters the radiator. The other valve, referred to as the lockshield valve, balances the system by regulating how much heat the radiator gives off.
What side of the radiator is the lockshield valve?
The lockshield valve is located on the side of the radiator opposite the on/off valve.
How to change a radiator valve without draining the system?
To change a radiator valve without draining the whole system, start by turning the heating and water off, then protect the floor around the radiator under the valves to catch any excess water. After that, prepare the radiator valves by removing the nuts and adaptors on the new valve and smear it with the PFTE tape that joins to the radiator. Next, release the stored pressure, then open the old valve on the flow pipe. Once the thermostatic valve or manual is open, release the pressure, drain the radiator and remove the old thermostatic valve. Finally, you can attach the new thermostatic valve or manual valve, remove the old lockshield valve, and connect the new lockshield valve to finish.
