How To Correctly Install A Radiator

After the Radiator is mounted onto the wall the next step is piping and correctly installing the radiator in the safest way possible. Now let’s go through this together...

1. Firstly, turn off the hot water and leave it to cool for half hour or so. This allows you time to prepare for the radiator installation and removal, gathering all the equipment you need.

2. Next, turn off the specific radiator you are planning to replace by turning the plastic handle clockwise. At the far end of the unit there should also be a protective cap, which is also known as the lock-shield valve. Remove the cap, and close this valve using an adjustable spanner by turning it clockwise too. Make sure you count the number of turns as you go, because it needs to be turned back the same number of times once the new radiator is fitted to ensure even distribution and a balanced hot water system.

3. Now you can bleed the radiator to get out any excess water. Turn the key at the far top corner and have a cloth or small container ready to catch any liquid that might drain from the unit.

4. The radiator is now ready to be removed! Grip the valve assembly at the bottom of the model with a steady wrench to prevent it being pulled loose along with the unit itself, and then undo the necessary nuts and bolts before hoisting the radiator from the brackets on the wall (be aware that you may need an extra pair of hands at this point if the radiator proves to be slightly heavier than you were expecting!)

5. Once the unit is removed you need to drain any excess water still inside; simply hoist it at an angle and allow the liquid to flow directly into a bucket or container you’ve already positioned into place.

6. Dispose of the old unit safely and carefully – preferably outside or in a hire skip if you can afford it.

7. Now the new model is ready to be installed. Fitting a radiator becomes a little trickier at this point, so take your time and don’t rush any of the next steps – you don’t want to break anything before the unit is even up and working.

8. Before you fit a radiator, you should wrap a short length of PTFE tape around the thread of the unit, this keeps it secure while you’re attempting to manoeuvre it into position.

9. Next, lift the unit onto the walls and make sure its securely in place.

10. Fitting radiator valves is a delicate job, so you should also make certain that these are correctly positioned before using the wrench to bolt them down permanently.

11. If everything looks as it should, tighten the valves while holding the valve assembly in place. Don’t over-tighten the valves, as you will only end up with a faulty system that doesn’t heat properly and have to start all over again.

12. Now, open the bleed valve at the top and the flow valve at the bottom of the unit. The flow valve is essentially you’re on/off switch by which you can control the temperature of your radiator. Wait until water begins to leak from the bleed valve, and then close both up – your radiator is now filled with water.

13. Open the return valve (or lockshield valve) at the bottom of the model by the same number of turns as you did before, but this time turning it anti-clockwise; this allows the water to circulate and distribute evenly throughout the radiator.

14. Finally, check for leaks and switch on the hot water to test out your new model – your new radiator unit fitting is all complete!

Any there you go, all installed and fitted in a safe and structured manner.
