If it is a combi boiler you also need to let more water into the radiator loop as you let some air out - should be above 1 bar on the pressure gauge on the combi. You have tried bleeding it haven't you?

no, it's too cold as I still don't know how to bleed the radiators

Make sure you fill up with inhibitor afterwards.

This is worth repeating. Without inhibitor steel radiators in electrical contact with copper pipes set up a nice little electric cell while the radiators dissolve from the inside......

Hot and cold spots, flushing, bleeding?

Sounds like the menopause to me. I suggest you apply some patches.

If it's a combi boiler in a studio flat, with a radiator loop of one radiator near the boiler, for example with both in the kitchen, it may be cheaper to ditch the radiator and its pipe work and refit the lot from scratch with new gear.

Haven't got time to read the whole thread so sorry if someone's already suggested it but it sounds like the radiator(s) need bleeding.

I have just read the whole thread...

I think that bleeding the radiators may well be in order.

I never read threads but when trying to fix heating problems, always bleed the radiators first.
