I'd be so grateful!
1) If the water in the rads and pipes is so hot that I can't touch the rads, is it possible that I can hear it rushing and coursing through the rads and pipes? I've been told the noise is air in the system, but I'm wondering if it's boiling hot water instead.
2) When bleeding/venting rads, no air is coming out but sometimes the water spurts out (rather than trickling). When it spurts out, is that because there's air coming out too with the water?
3) Is it normal for my rads to go stone cold and the whole house become freezing and for it to take over an hour before the room thermostat tells the boiler to come back on to heat the house? I'm boiling hot and then freezing cold all evening!
