Tackling a heating project can be confusing, but the right radiator accessories are crucial for a flawless finish. Whether you're installing a new radiator or simply upgrading an existing one, this guide is your definitive resource for understanding everything from radiator valves to pipe covers, ensuring you have the right parts for the job. Our focus is on home central heating systems, so you can be confident you're in the right place.

The Essential Radiator Accessories Explained

Choosing the correct components for your radiator is about more than just functionality; it's about control, stability, and a polished aesthetic. We break down the key parts to help you understand their purpose.

Radiator Valves: The Heart of Your Heating Control

Radiator valves are a fundamental component, designed to control the flow of hot water into your radiator and regulate its heat output.[1, 2] There are two main types:

Manual Valves: These operate just like a traditional tap, requiring you to manually turn them to increase or decrease the heat.[1, 3]
Thermostatic Radiator Valves (TRVs): More advanced and energy-efficient, TRVs feature a built-in thermostat that automatically adjusts heat output based on the room's ambient temperature.[1, 3]

For a clean, professional finish, radiator valves are available in a variety of shapes—angled, straight, and corner—to suit different pipe arrangements.[3] You can also find a wide selection of finishes, from classic chrome to modern matte black and rustic brass, to perfectly match your radiator.[4]

Radiator Wall Stays & Brackets: Stability Meets Style

Wall stays and brackets are essential for safety and stability. Their primary function is to anchor your radiator securely to the wall, preventing any movement or accidental damage, which is especially critical for heavier units like cast iron radiators.[5, 6, 2] It is vital to ensure the wall itself is strong enough to comfortably support the radiator's weight.[2] Proper installation involves securing the wall plate, inserting the threaded rod, and then adding the front clamping plate and nut to hold the radiator in position.[7, 8]

Radiator Pipe Sleeves & Covers: Concealing Pipework for a Polished Finish

Radiator pipe sleeves, also known as pipe shrouds or covers, are decorative accessories designed to elegantly conceal unsightly pipework.[9, 10] They are a simple yet effective way to achieve a clean, streamlined aesthetic.[10] Different types offer varying levels of convenience and durability:

Snap-on Covers: These are incredibly popular for their ease of installation, as they simply "snap" over your existing pipes without the need for tools or adhesive.[9, 11] They are available in finishes like chrome or brass to match your other fittings.[9]
Self-Adhesive Covers: A no-fuss solution for a quick cosmetic lift, though their finishes may be less durable.[9]

How to Bleed a Radiator

If your radiators have cold spots, it’s a sign that trapped air is preventing efficient heating. Bleeding them is a simple fix to restore optimal performance.[3]

First, turn off your central heating system and allow the radiators to cool down completely.[12]
Use a radiator key or a flathead screwdriver to open the bleed valve.[13]
Turn the valve a quarter-turn anti-clockwise; you should hear a hissing sound as air escapes.[14]
Once water starts to come out, turn the valve clockwise to close it. Be careful not to overtighten to avoid damaging the thread.[12]
Use a cloth to catch any drips.[12]

A Step-by-Step Guide to Fitting Radiator Wall Stays

Wall stays are essential for securing your radiator, especially for heavier models. Precision is key for a safe installation.[7, 8]

Attach the wall plate securely to the wall at the correct height using an appropriate plug.[7, 8]
Screw the joining spigot or threaded stud into the wall plate.[7, 8]
Trim the threaded rod to the correct length, depending on the depth of your radiator.[8]
Carefully slide the radiator into position, ensuring it's aligned with the brackets.[7, 8]
Add the front clamping plates, washer, and nut to secure the radiator in place.[7, 8]
