i had a heatrae sadia electromax boiler(9kw) fitted back in august and 6 new rads.(a whole new system replacing n s h). In the last 2/3 weeks i have noticed a sound comming from the 2 rads closest to the boiler which sounds to me like a blowlamp running. The system works as it should and no alarms are flashing at me, but this bloody noise is really annoying.I have tried turning the trv down on each but it doesn't seem to work.The pipe work is all copper and surface fixed, all clipped nicely and no leaks. The 2 rads mentioned are on the same pipe run and the rad in the lounge below is T'ed off from these. The 2 rads are 1000 singles and the one below is 1000 double.I hope that is enough info for an expert, i am just a lowly carpenter!Please help, it's driving me mad.

Have you checked the rads for air.
check for air, check valves are all open...if you do blead and its a sealed system...check your water pressure gauge afterwards...should be 1 - 1.5 bar.
