If your cast iron radiator weighs over 100kg it will be split into two or more sections to ensure it arrives safely. This means you will need an additional piece of kit called a joining tool to connect each section of your radiator together. But don't sweat it. We will provide a joining tool and ask that you please return it to us when you are all done with it. You can find out more about the handy extras we provide in our central heating inhibitor guide and central heating inhibitor guide and how to avoid corrosion guide have got you covered.
