Frequently Asked Questions
What accessories do I need for my cast iron radiator?
To get your radiator working and safe you will definitely need radiator valves to control the heat and wall stays to prevent it from falling. You may also want pipe sleeves to cover ugly copper pipes and make the finish look neat.
Why do I need wall stays for cast iron radiators?
Cast iron radiators are extremely heavy and can cause injury if they tip over. Wall stays are metal brackets that anchor the radiator to the wall so it stands firm and cannot be knocked over by children or pets.
How many wall stays should I use for one radiator?
We recommend you install one wall stay for every 10 sections of your radiator. If your radiator is very long or heavy using two or more stays will give you the best stability and safety.
What is a cast iron radiator joining key used for?
A joining key is a long metal tool used to connect separate sections of a radiator together. You will need this tool if your large radiator is delivered in pieces and needs to be assembled in your home.
What is the difference between manual and thermostatic valves?
Manual valves work like a simple tap that you turn on and off by hand. Thermostatic valves are smarter because they sense the room temperature and automatically adjust the heat flow to save you money on energy bills.
What are radiator bushes?
Radiator bushes are circular fittings that screw into the four corners of your radiator. They act as adapters that allow you to connect your valves and air vents to the main body of the radiator.
Do I need pipe sleeves for my radiator installation?
Pipe sleeves are not technically required for the heating to work but they are highly recommended for style. They slide over your standard copper pipes to match the colour of your luxury valves and give a professional finish.
How do I use the radiator touch up paint?
If you accidentally scratch your radiator during installation you can use our touch up paint to fix it. Simply apply a small amount of the paint to the scratch with a brush and it will blend in with the original finish.
Why is there a deposit for the heavy duty joining key?
The heavy duty joining key is a specialized professional tool that is expensive to manufacture. We charge a deposit to ensure the tool is returned to us safely after you have finished building your radiator.
Can I install cast iron radiator accessories myself?
You can easily fit simple items like pipe sleeves or wall stays if you have basic DIY skills. However we strongly suggest hiring a qualified plumber to install valves and join radiator sections to prevent water leaks.
How do I stop my cast iron radiator from leaking?
Leaks often happen if a connection is loose or a rubber seal is worn out. Check that your valves and joining nipples are fully tightened and ensure that the thread tape or hemp is applied correctly to the joints.
What are radiator end caps used for?
End caps are used to plug the open holes at the end of a radiator section that are not being used for valves. They ensure the water stays inside the radiator and help maintain the correct pressure in your heating system.
How do I choose the right size valves for my pipes?
Most homes in the UK use 15mm copper pipes for heating. Our valves are designed to fit these standard pipes perfectly. You just need to decide if you need angled valves for wall pipes or straight valves for floor pipes.
Why is my radiator cold at the top?
If your radiator is hot at the bottom but cold at the top it usually means air is trapped inside. You can fix this by using a radiator key to open the bleed valve until the air hisses out and water appears.
Do your accessories match the radiator colours?
Yes we offer a wide range of finishes including brass chrome and black. You can select wall stays and pipe sleeves that perfectly match your radiator valves to create a beautiful and coordinated look in your room.
What is the best way to clean my radiator accessories?
You should wipe your accessories gently with a soft dry cloth to remove dust. Do not use harsh chemical cleaners or wet sponges on metal finishes as this can damage the protective coating and cause rust.
Can I use these accessories on old reclaimed radiators?
Yes most of our modern accessories like manual valves and wall stays are compatible with vintage radiators. You just need to check the thread sizes on your old radiator to ensure the new parts will screw in correctly.
What is a radiator bleed valve?
A bleed valve is a small air vent usually found at the top corner of the radiator. It is an essential part that allows you to release trapped air so that hot water can fill the entire radiator and heat your room efficiently.
How tight should I screw in the radiator valves?
You should tighten the valves enough to create a watertight seal but be careful not to over tighten. Using too much force can crack the nuts or damage the rubber O-rings which might lead to leaks later on.
Do I need special tools to install wall stays?
You will typically need a drill to make a hole in your masonry or timber wall and a screwdriver to secure the bracket. It is a standard job but always check for hidden wires or pipes in the wall before you start drilling.
