When should you bleed your radiators?

Many modern radiators provide heat by having hot water pumped through their pipes. During the summer months when heating is not in use, or if the system is drained, air can enter these pipes. This air causes issues with the water flow, requiring you to ‘bleed’ the radiator to release any air from the system. Not doing so will lead to your heating taking much longer to warm the house which may result in a much larger than expected bill. A few signs that your radiators need bleeding include:

  • Strange noises coming from the radiator – Radiators should not gurgle, rattle or bang and this is a strong sign that air is trapped inside. Your radiator shouldn’t contain any air at all, only water.
  • Cool patches – A common sign that a radiator needs bleeding is part of the radiator not warming up. Often, the lower half of the area will warm up whilst the top remains cool, although cold patches may be evident in any part of the radiator. This is caused by trapped air in the cool area which has displaced the hot water. Bleeding your radiator will release the air, allowing the hot water to flow freely.
  • Damp or mould around the house – The presence of damp or mould around the house can often be an indicator that your radiator is not working as it should. Uneven heating through the house can cause condensation, leading to these patches of mould.

These symptoms indicate that your radiators should be bled as soon as possible. However, to avoid your heating becoming ineffective in the first place, it is recommended that radiators are bled at least once a year. Ideally, this should take place at the beginning of the heating season before the radiators are put into use. Remember, this simple maintenance task will ensure comfort in your home and help to save some cash for the things that are really important.
