The only hum which would be continuous when the boiler is on will be the pump. This can sound quite loud if the vibration is travelling down the pipes, try clipping the flow and return under the boiler and see if this reduces the noise.

I have exactly the same boiler installed just under a year ago and have the exact same problem with the noise. I had a vaillant engineer come out and said it was not the boiler but thinks the water rushing through the pipes is the cause. I'm not sure but theres basically nothing I can do about it. Only thing Is you will slowly get used to it.
