Looking for a change? Whether you’re wanting to upgrade for better efficiency, renovate your space, or bid farewell to an old companion, this guide has you covered. We’ll walk you through the steps of a radiator change, unravelling the why and how for a seamless transition in your home’s heating system.
12 Steps for Changing Your Cast Iron Radiator
Whatever the reason for changing your cast iron radiator, follow this straightforward 12 step process for a seamless, safe and structured experience when upgrading your home’s heating system.
- Turn Off the Heating System
Begin by turning off the heating system and allowing the radiator to cool.
- Drain the System
Use a radiator key or valve to open the bleed valve on the radiator, letting water drain into a container. Alternatively, use a hose to direct water outside.
- Prepare for Water Leakage
Place towels, buckets, or a plastic sheet under the radiator to catch any remaining water when disconnecting.
- Loosen Valve Connections
Use an adjustable wrench to loosen the nut connecting the radiator valve to the pipe. Use a bowl or bucket to catch any water that may spill during this step.
- Disconnect the Radiator
After draining water, disconnect the radiator from the valves. Lift the radiator slightly to detach it from the wall brackets or floor supports.
- Cap or Plug Pipes
Cap or plug the exposed pipes to prevent water leakage. This step is crucial if the heating system will remain operational without the removed radiator.
- Secure Radiator for Removal
If the radiator is large, have assistance to help lift and remove it safely. Secure the radiator to prevent accidental tipping or damage.
- Seal Valve Connections
Seal the exposed valve connections with caps or plugs to prevent water and air from entering the heating system.
- Cap the Floor Openings
If floor openings are left from removing floor supports, cap them to ensure safety and prevent drafts.
- Dispose or Store the Radiator
Decide whether to dispose of the radiator or store it for future use. If storing, ensure it’s in a dry place to prevent corrosion.
- Install the New Radiator
Follow the manufacturer’s instructions for installing the new radiator, ensuring a secure connection to the valves and proper support.
- Repressurise and Bleed the System
If necessary, repressurise the heating system and bleed radiators to remove air pockets.
