Boiler HELP - It's FREEZING!

[mybrownbearbarney]

Just wondering if anyone is an expert on boilers ....

I've had gurgling radiators since the heating was turned back on a couple of weeks ago. While a plumber was fixing a tap for me on Wednesday, I asked him to sort out the gurgling. He bled the radiators and said that the pressure on my Keston Celsius 25 was too low - he raised the pressure to 1 - 1.5.

The boiler is on the ground floor and there are radiators on this floor and two further floors. The pump is on the first floor - but enclosed behind a washing machine/dryer and not accessible without removing panelling.

The gurgling has now stopped but suddenly the radiators are not heating up - only mildly lukewarm and we're freezing (a couple on the first floor are warmer than the others). Is it pure coincidence that this happened after the pressure was raised? I have a Keston engineer coming - but not until midweek. Is there anything I can do in the meantime??? I know absolutely nothing about heating systems but am willing to learn quickly as it is soooooo cold!

Thank you.

mine always went wrong after a bled them. sounds like the pressure needs to be taken up again.

Put the heating on, bleed the radiators again (start at the bottom of the house and work your way up) and then top up the boiler to increase the pressure to about 1.5 bar.

Thanks - will try bleeding them again.

similar problem here - downstairs is fine, upstairs tow of ht rads are cold. I have bled them but they go cold again straightaway, so i assume air is getting into the system somewhere. Any suggestions?

It could be that the flow of water through the rads is too fast - try turning the valve on the side a quarter turn and see if that helps.

Did it work?

DH has taken over - this will the next thing to try on his list once he has bought a new key. Yesterday he turned all the downstairs rads off to see if that made a difference upstairs - no. Then the rad key snapped so that was the end of that! There is air getting in, but from where???
