Fixing TV onto Wall - Strength of Aerated Concrete Wall

[PhilipJ]

Hi,

I am wanting to fix my TV onto the wall. The wall directly behind the TV is a metal stud wall so has no strength, so I need to mount the TV on the side wall (a solid wall) with the TV on a long arm.

Intended TV position

I am concerned that this puts a lot of horizontal force on the wall (equiv ~28kg).

The wall is a dot and dab onto aerated concrete blocks (H+H Celen Blocks Standard Grade (https://www.hhcelcon.co.uk/solutions/by ... con-blocks)
Will the wall support a 28kg side load? The TV stand says it will support TVs up to 25kg, but even with a 11.5kg TV, it seems like when I hold the TV stand up with TV, this feels lie it will put a large load on the wall. Any advice would be very welcome.
TV stand is Vogels THIN 545 (https://www.vogels.com/en-gb/c/thin-545 ... ount-black)

Many thanks,
Phil
