Constantly having to bleed radiators

[fasteddy1234]

Hi there,

I have to constantly bleed 2 of the radiators in my house. We're talking about once every 2 weeks. Ones upstairs and the other is downstairs.

Also I can hear alot of gurgling from both rads, and the occassional LOUD Gurgling...

Any Ideas??

Thanks

One ov 2 things or both if water in radiator is black sludge like then it needs flushing out, sludge makes air in heating system. Or you have a small leak on system drawing air into sytem all the time whan pump is on.

If this is an open vented system rather than a combi, check your header tank. There have been a few problems in this forum concerning water gushing from the vent pipe back into the tank If this happens, the water in your system picks up a new supply of dissolved air every time it goes over the top.

I should also add that dissolved air speeds up corrosion. The sooner you get to the bottom of this the better.
