Does anybody still do this?
These new condenser boilers are supposed to be a air/water tight system, my heating has just kicked in and heard a gurgling from the hallway radiator, got the key out the draw and let a load of air out. They get hot when I run the hot water too  |

Yes you should still do it ....
Make sure you don't over-pressurise though...... best to have vocal contact with someone who can regulate the loop valve whilst you're bleeding each radiator  |

The radiators get hot when you have the central heating set to "Hot Water Only"? If so we had that a couple of years back and needed a plumber to come and fix it as it was during the summer.
As for bleeding them - we hadn't for years and always put the low level of heat down to the boiler (which was installed by the Romans I think!!) - plumber had to drain the system a while back and bled all the radiators and since then the house is positively toasty when we have the heating on.
So guess the answer is yes you do need to |

In a sealed system you shouldn't be getting "air" out of radiators, you may get a very small amount of hydrogen bubbling out but your talking tiny amounts.
If you're bleeding alot of air out regularly you may have air being sucked in on the negative side of the pump.

I havent messed with any of the valves under the boiler (ideal logic combi 30) and its set to hot water & central heating, i was led to believe that these new systems were maintenance free as they self fill/bleed once installed. But I have noticed that the rads have been cooler at the top... meaning air in the system, and bled them twice since moving in my flat in february, i know if i ring my council housing number I'll get fobbed off without an engineer seeing it. |

Iceland, but Aldi is closer.. |
Could be the system was poorly installed and never purged properly, high spots in runs will trap air, over time small amounts will be picked up with the water flow ending up trapped in the first radiator it encounters.
As soon as the radiator gets hot, the air expands with the steam and further reduces the volume of water in the radiator making the large cold areas.

"Your diverter valve in the boiler is jammed, probably with black sludge if you've been bleeding and topping up regularly.
"
That's very sexy... I like a man who knows his stuff... X |

Installed by council contractors so work quality unknown.
I bled rads while system was cold to avoid steam and pump disturbing air pockets in rads. |

Yea I still bleed mine, I'm with the housing trust, when my boiler packed in I called them they came and put a new one in but it took them nearly 3 weeks to do it, so I was left with out heating for nearly 3 weeks, hot water I still had but that took about a hour to heat up x |

"I go around them every year, just to check but it's largely resulting now in no air coming out.
I'm guessing it's a couple of weeks more until I have it on this winter"
I just set the room thermostat and leave it to come on and go off by itself. |

I had to re-pressurise my year old boiler last summer. I haven't had to bleed any of the new radiators yet. I can never remember which order to bleed them in. |
