I think I need to bleed the radiators!
We haven't long moved in here and had to have a new radiator fitted, got that done but didn't use the heating much over "summer"
When I have come to put it on recently, I have noticed that the upstairs radiators aren't warming properly
So.... I presume they need bleeding.. am I right?
I can go and get a key... have looked on a forum on the net about which order to do them in, it just says from highest point and work down... so doesn't matter which room 1st then?
Also... the heating has to be off for this to be done right?
If anyone knows anything I'd be real grateful!

Thanks in advance
