Chasing CH pipes using speedfit

[Muskopia]

I'm chasing some walls and using speedfit for pipes to the radiators.

I'll be using conduit and want to transition to copper ends which will connect to the rads. Can I bury the speedfit fittings (elbows etc)?

What are the options for pipe exiting the wall and connecting to the rads? Do I chase the walls in-line with the TRV's at each end?

Thanks!

Oh! Figured it out!

Pushfit stems.
One wall chase | pipes come out in middle behind radiator | 90 deg elbows splaying out pipe to each TRV
