Bleeding your radiators

Please see below the steps necessary to bleed a radiator:

  1. Check which radiators need bleeding by checking for cool spots, usually towards the top, when the heating is on.
  2. Wait until the radiators have cooled before attempting to bleed them.
  3. Have a cloth or towel to hand as this will be required to catch drips of water.
  4. Locate the bleed valve which can be found at the top of the radiator on either the right or left hand side.
  5. Ensure you have the correct key to fit the valve. Usually a standard square ended key is required which are available from B&Q and similar stores.
  6. Carefully turn the bleed valve anti-clockwise until escaping air can be heard, wait until water is drawn out via the valve into your cloth and the air bubbles stop ensuring you hold the key in place throughout this process.
  7. Tighten the valve back into place and wipe off any excess water.

NB: CVRL staff are unable to assist with this so if you are not confident with this task please consult a qualified plumber or heating engineer.

Changing your radiators

Some tips from our heating engineers and our Consultant: A word of warning: Under no circumstances install more radiators than originally fitted and do not use any kind of pump to overcome resistance. Any such changes will violate your lease agreement because these kind of changes will interfere with the balance of the system for the whole Village. Over the years, changes by some residents have caused lower temperatures and in some cases loss of heating. And now the Dos:

  1. Only engage heating engineers familiar with working on similar systems
  2. Only use steel or cast iron radiators, never aluminum
  3. Only use steel or copper pipe with the appropriate metal fittings. Never use push fit plastic fittings or galvanised steel pipe
  4. Pressure test all work to 35 meter head before reconnection to main system
  5. Check and re-check that all components used are suitable for the system pressure
  6. New radiators should have the same output to the ones you are replacing
  7. Although installing thermostatic radiator valves is a good idea to control the temperature in the rooms, be aware that the system is old and therefore water circulating carries sludge/dirt which could result in sticking radiator valves​
If in any doubt contact our Managing Agents BEFORE you carry out any work or spend any money
