Bleeding radiator

It is important to regularly bleed the radiator, as this ensures the optimal heat distribution in your home. If the bleeding is not done you will find that the radiator feels cold or that the heat distribution in the radiator is uneven.
Below you will find a guide for bleeding a radiator system.

Bleeding radiators should be done as often as necessary. Most often this is one a year. If the radiator keeps filling with air, this should be done more regularly.

At City Apartment you will find several small tips, tricks and guides for the apartment maintenance. The few steps make a huge difference and make your home even more comfortable to live in.

Best way to bleed radiators

Fortunately, venting radiator is easy and straightforward and you do not have to hire a professional.

There are two types of radiators in the City Apartment homes:

  • A type of radiator where a wrench or parrot pliers must be used
  • A type of radiator where a radiator spanner must be used

The type of radiator can be recognized by the following:

  • If there is a metal screw, a wrench/parrot pliers must be used
  • If there is no metal screw and just a small thread, a radiator spanner must be used

Bleeding of radiator with key

Bleeding radiators with a wrench or parrot pliers:

  • Turn up the heat at the highest temperature. This ensures free passage

  • You find a small metal screw (typically at the opposite end of the thermostat). This is loosened with the wrench or parrot pliers

  • Turn counter-clockwise. Put a cloth around the screw or just below, as water comes out the small valve. If there is air inside the radiator, you will hear a hissing sound. Eventually, water will come out and you can close it again. It is important to have a cloth below the screw, as the water may be black and discolour the walls

  • Close the screw clockwise. It should not be tight, just closed

  • Remove air from radiator regularly to get the optimal effect

Bleeding radiators with a radiator spanner:
Basically, you remove air from radiator with a radiator spanner the same way as with parrot pliers.

  • Turn up the heat at the highest temperature. This ensures free passage

  • There is a small thread in the radiator (typically at the opposite end of the thermostat). This is opened using a radiator spanner

  • Turn counter-clockwise. Put a cloth around the thread or just below, as water comes out the small valve. If there is air inside the radiator, you will hear a hissing sound. Eventually, water will come out and you can close it again. It is important to have a cloth below the thread, as the water may be black and discolour the walls

  • Close the thread clockwise. It should not be tight, just closed

  • Remove air from radiator regularly to get the optimal effect
