Domestic Hot Water flow restrictor position - help required

[fist_me_gently]

Hello,

I'm having trouble with my hot water flow to the taps in my house, I'm relatively certain it's the flow restrictor. When I watched the guy pipe it in I remember him dropping it in but I can't for the life of me remember where it went. I've had several unsuccessful attempts at locating & removing it.

Hopefully someone can point me in the right direction, I've taken a picture of the boiler for reference.

Any help will be greatly appreciated, thank you

second pipe in from the right hand side. Turn water off and open that nut facing

I have had both the far right and the second from the right elbows out and there's no insert in either... Could it perhaps be up inside the boiler? I didn't pay much attention at the time to where it was placed..

Anyone else?
