Hi all. First of all - I am a total newbie when it comes to DIY and I have never did much of it, so apologies for any silly questions.
Me and my girlfriend have recently moved into a 2 bed house with CH. We've previously lived in a flat which had electric heating, and so I don't really know anything about CH.
I did some research on web though...
The pressure in our boiler is really high, it oscillates between 2.5 and 3, where 3 is the max the boiler can handle - according to the dial.
Apparently the most common cause of that is air in the CH system. The remedy is to bleed the radiators, which I intend to do as soon as my radiator key arrives (yes, I didn't have one!).
I switched the radiators on tonight to check which ones need bleeding - and the internet teaches us ( icon_wink.gif ) that it's the ones that are not fully heated at the top parts...
Unfortunately mine were cold at the bottom parts (all of them), and I had to switch the heating off as the pressure was getting to 3.5, which was already at the red mark on the pressure dial.
So my question is - what should I do? Do I bleed them all? Will this cause massive pressure drop and a need to re-pressurise the boiler? I need some guidance and advice, as the nights are getting cold and we really need to start heating the house...
Thanks in advance for any kind advice and help!
