Radiator accessories determine whether your radiator is mounted securely, connected correctly, and controlled efficiently. This range includes around 40 products from Belrad and Radiva, from floor brackets and J-brackets to radiator valves, thermostatic heads, and complete connection kits. Prices range from approximately £1 for individual small parts to around £130 for a complete set with thermostatic control.
Which Radiator Accessories Do You Need?
The type of radiator you have determines which accessories are required. For a panel radiator, J-brackets are the right choice — available for radiator heights of 500 mm, 600 mm, and 900 mm. A designer radiator or towel radiator requires a dedicated mounting set, available in white, matt black, and chrome to match your room's finish. If you're fitting a towel radiator, you'll also need separate towel bar buttons.
For the connection, check the thread type and pipe diameter. Most domestic radiators use a 1/2" connection, and the radiator connection kits in this range are designed to match. For control, choose between a thermostatic head with an M30 x 1/2" connection or a 900 W electric Wi-Fi thermostat, suitable for electric bathroom radiators. A quick overview by type:
- Panel radiator: J-bracket (H500, H600, or H900) + 1/2" radiator connection kit + thermostatic head M30 x 1/2"
- Bathroom radiator: mounting set in white, matt black, or chrome + radiator connection kit + optional 900 W Wi-Fi thermostat
- Towel radiator: mounting set + towel bar buttons
Installation Tips
A common mistake is fitting a thermostatic head onto a valve with a different thread size than M30 x 1/2". Always check the thread type on your existing valve before ordering. An adapter can sometimes resolve a mismatch, but it also increases the risk of leaks when the system first heats up.
Frequently Asked Questions
Which radiator connection kit do I need?
This depends on the connection side of your radiator and the pipe diameter in the wall. Most domestic radiators use a 1/2" connection, which is also the most common size in this range. Always check the connection sizes in the product description before ordering, as an incorrect size will cause leaks.
What is the difference between a J-bracket and a floor bracket?
A J-bracket is fixed to the wall and holds the radiator away from it. A floor bracket sits on the floor and supports the radiator's weight from below. Which one you need depends on your wall construction and radiator type — with a hollow or partition wall, a floor bracket is often the safer option.
Can I adapt an existing radiator to a different connection?
This depends on the radiator type and its current connection position. With the right radiator connection kit, you can often change the connection side, but a centre connection requires a specific kit designed for that purpose. Check the product description carefully, or get in touch if you're unsure about compatibility.
