Air in mains water system

[Bob.joneshome]

I have a mains feed unvented Ariston Primo indirect hot water cylinder on the first floor and mains cold water throughout but over the past few weeks the water is spurting from the taps as though air is trapped. I have tried running all the taps to clear the air but within in a day the spurting is back soaking anybody in close range. I think the problem could be somehow connected to the heating system as when the taps are off a can hear the sound of bubbles rising up the pipes (don’t know which ones as boxed in) which feed the unvented hot water cylinder. The heating system is feed form a header tank in the loft.
Any suggestions?

Sounds like air in the water supply.

I suffer from excess air sometimes, can I blame the water company or is it the brewery's fault?
