One Radiator Not Working

One Radiator Not Working


Have you had that one radiator not working at your home?

Before doing anything else, you must know what to check first.

Identify the Problem

Is your radiator not heating up in a specific part of your house?

It can either be that on the 2nd floor and above, one radiator is not heating up or vice versa where your radiator is not heating up in the basement and is working on the succeeding floors.

The reason for radiator not working above is either the pressure is not enough or there could be air trapped inside the pipes. To have an exact pressure in the basement where the boiler is located should be 4, on the first floor you will add another 5, and then succeeding each floor. If you have a normal or regular valve then manually adding the exact pressure can help or is necessary.

If your radiator is not heating up below, most common reason for this is that there may be blockage due either system is old. Dust and rust build up gradually in your central heating system. That’s why most people suggest you have to flush it out by contacting an engineer for it.

This must be done quickly to avoid paying high electrical bills. Flushing may take some time depending how large your heating system is but it will be worth it instead of enduring the cold weather during winter season.

Learn How to Bleed your Radiator

Bleeding your radiator is a simple repair method that anyone can do.

What you need are a Radiator key, a bucket, and a used cloth.

Before checking the floor or room where the radiator is not working, make sure to turn off your heating system first. This is necessary to avoid first degree burns due to contact with hot water to your skin.

Once the heating system is off, hold your radiator key and insert it on the valve located above.

The correct way to do this is to rotate the radiator key slowly from right to left. On the other hand, hold the cloth covering the valve to be sure you won’t be splashed with hot water or air. This is done to slowly let the air out. You will hear a fizzle sound until slowly fades away.

Rotate the radiator key from left to right tightening the radiator valve.

Take note that the pressure will drop so you need to manually add the exact pressure.
