Bleeding a radiator is a very simple job, but you need the right tools. Do not use a pair of plyers because if you cannot turn the radiator valve to the off position it will flood the room until your central heating system has emptied.
The correct tool for bleeding a radiator is a “radiator key” this key will fit snuggly onto the valve and will open up the valve so the air can escape.
As the air releases the water can rise to the top making your system more productive with more heat emitting from your radiators!
Bleeding A Radiator
Here are the steps needed to bleed a radiator and make it more energy-efficient. The more water you have in your radiator the hotter it will become. After the summer months when radiators are not used they will become full of air, so once a year you must keep on top of your radiators.
Start at the top of the house and check the overall pressure after you bleed each radiator. If there is not enough water in the system then the pressure will drop and you should top up the water pressure by a switch or a filling loop.
- Grab a radiator key, towel or bowl in case of leaks
- Push the key into the TOP valve
- Turn left NOT right, lefty loosey and righty tightie
- You will hear a hissing sound, this is the air escaping
- As soon as you hear water spitting out turn the radiator off (right)
- Your radiator is not full of water for maximum heat!
- Check the overall boiler pressure, located behind the front panel
- If the pressure has dropped just top-tup the system
- You have successfully bled a radiator
- Now continue doing this until all radiators have been bled
Conclusion – Bleeding A Radiator
Once you have mastered bleeding a radiator, you should continue doing this each year for maximum heat and efficiency from your boiler/heating system.
If your pressure is not rising or your radiators have no water left in them then you will need to bring in a boiler/plumbing expert to help fix the issue. If you have any questions not covered in this simple how-to guide then feel free to ask in the comment section located below!
