Getting air out

[Wibbly]

I have an ecoFit pure recently installed and hear what sounds like air circulation as the boiler fires up the CH from cold. None of the rads are cool at the top suggesting they've been bled correctly.

How would I go about removing the rest of the air? Previous boiler (in the same location) did not do this.

If you know what you are doing then you can get into some parameters on the boiler controls there is a purge phase which should help, but you should really get your engineer back as this is part of the commissioning of the boiler

If its persistent, like for more than a week then I'd recommend getting the installer back.
Going back to issues like this is part of the job that you've already paid for.

Thanks. Pain that I only notice when it's starts from cold, not once warm, so difficult to reproduce on demand when he turns up, or prove he's fixed it...

Is it symptomatic of anything in particular, in general?
