Hi
I've recently changed my central heating pump, and also flushed and inhibited the system, which is a conventional boiler, not a combi. I have noticed that the pipes have started to 'creak' when the boiler is on, and this is particularly apparent intermittantly just as the boiler is reaching max temp and then after the thermostat shuts it down...
The creaking sounds like expansion/contraction noises, but I wonder why this has only just started??
I've also just noticed that one of the rads upstairs had quite a bit of air in it, but i've never had a problem with the system gasing before. Could the inhibitor be causing this? It may well just be residual air left over from the draining/refilling when I flushed it.
Any ideas?
Thanks
