Moved into a brand new house with the following set up:
Potteton Promax HE
Twin zones (Zone 1 = bottom floor and Zone = top two floors) via Siemens controls
Big Kingspan HE cylinder and teeny tiny radiators (I'm used to living in older houses - LOL)
The radiator in the main bathroom which is adjacent to the airing cupboard (which houses the pump, expansion tanks and cylinder) doesn't have a TRV and comes on when there is a call for hot water. I can turn it off via the lock shield - but before I talk to the builder, all I really want to know is 'Should this happen? If pics of the install will help then I will post these.
Thanks
PS I have also had to bleed the top floor rads on two separate occasions - is it usual to have trapped air in brand new systems or should this have been sorted by the installer?
