constant need to bleed

john1963

I have a radiator that needs to be bled everyday. Any ideas what might be needed. Thanks

To save on work an automatic bleeding valve can be installed. This demands no atention and removes the air automatically.
Available from the plumbing shop and DIY markets.

But such a lot of air in the radiator indicates a faulty CH system. Get a heating engineer to have a look at it. There are many possible reasons for air diffusion into the system.

Your CH system isn't balanced. Get this done.

Before you go and spend money on a heating enginneer. Can you confirm if this rad is upstairs in your property or if its a single storey property.

and do you have a sealed or open vented system. The answer to this question can disgard the use of an AAV and allow further advice. As an AAV fitted to a rad on a sealed system.Would be of as much use as a chocolate fireguard for open fire.

If it needs to be bled everyday then water is getting out of system. So look for signs I.e stain on ceiling or on overflow pipe outside. If it's an open system it could be going back up cold feed or pitching back up through expansion pipe.

Its not recommended to fit auto bleed valves to rad , thats bad advice , you will be introducing fresh water to the system on a regular basis causing corrosion , fitting these is only masking the problem , you need to find out if you have a leak , it appears you do

I had that problem a few years ago. it turned out that there was a leak in a gunbarrel pipe under a concrete floor.

+1 on looking for a leak somewhere,even a weep at a joint over time will drop the pressure,
if you cant find the leak you might try putting a can of oxipic or fast stop into the system although this stuff only really works for small a loss of pressure
how often do you have to introduce water into the system ????
