Washroom Radiator Taking in air

[mick4810]

Hi
Have a radiator in the downstairs washroom that is connected directly to boiler (not combi) which needs bleeding every couple of days. It was not doing this until I had a radiator replaced two months ago.

Any ideas I can't see any leaks.

Thanks

Is your heating system open vented (tank in loft) or sealed (red expansion vessel)?
