radiators in series

[farm boy]

I am planning to put two radiators in a bedroom should I plumb them in series with just one TRV on the first one or not.

Not. The first will emit the majority of the heat, with the second only having the residual heat to use. Connect in parallel, each with their own TRV

Thought the title was a Netflix box set

Don't do it! Take it from someone with a single pipe system (me).

Thanks, will do.
