New build heating system buzzing

[Aeropars]

Hi All,

I've recently moved into a new build house and when i moved in the heating system was fine and almost silent.

The other day I came home and noticed a loud buzzing/humming like something was vibrating and because of the stud wall construction, the sound was loudly reverberating around the house.

I tracked this down to being in the cupboard where the hot water tank is stored. I have a boiler which heats the water and the tank also has an emersion heater as a backup. The emersion is never on.

Before I go back to the builder I wanted to get some advice from those who are more experienced at this than me. the fact that this was almost silent suggests that there is something wrong here. Can anyone tell me what it might be and if theres anything I can do to remediate it?

Any help apreciated!

Just to add, the water system is a Tribune HE system if that helps.

Possibly the pump if it is in the cupboard.
Could be one of the zone valves has closed and there is no by pass fitted.

Thanks for the reply.

I gather then, it's not something I can deal with?

And I also assume I am right to report to the builders? Some of the stuff I have reported to them they have dismissed as normal so I want to be as clued up as I possibly can before approaching them.

report the buiders for what ? and to who ? you would be better finding out what the problem actually is before doing anything else

It might be the two port valve on the cylinder if its a sunvic as the forces from the moving magnetic fields make the wires physically move at the same frequency; when they move, they move the air, creating sound waves that you hear.
