Rad in bathroom needs bleeding every day.

[cliff1010]

I Had a new boiler installed early 2014 so could get them out but if a simple fix I will do it to save taking a day off work. All rads heat up but one in upstairs bathroom has to be bleed to get it hot it stays hot all day and next on period requires bleeding ? The system has a header tank so if I am correct does not need to be re pressured via filler pipe. The boiler is a Worcester Bosch greenstar RI. (lPG). Any ideas on what I can do
Thanks Cliff

Fit an automatic bleeding valve on the radiator.

Is it air or hydrogen? Either way it should be corrected.

Terrible advice...you're just masking a problem with the system.

There's either problems with the pipe configuration or leaks on the system allowing air to be drawn in and collect in this rad.

Thanks for the advice, I ordered one of these valves but the other advice is good and I need to rectify it moving forward.

The pump was replaced last year 2013 (new pump)
The boiler was replaced in Mar 2014
The rads/ system was power flushed in 2013

Any ideas where the air could be getting in ?

Hi Cliff,

Our bathroom radiator is connected to the hot water circuit still and this radiator (just this one) constantly has air in it. Our pump is on the lowest setting. I use to use an Aladdin value but this has now failed (2nd one).

I'm told the radiator on the hot water circuit will always catch air as it is almost acting as a vent for air trapped in the hot water circuit.

Not much help I know!

thanks any advice is helpful, I am going to check the pump setting tonight it's just strange it's only started recently. But saying that when it was installed in March we didn't have the heating on much so maybe it's something to do with the install of the boiler.?

Post the boiler make and model and pipe layout.

It is not normal for radiators/towel radiators to collect air...there is a problem.
