Are you saying the pipe i connect to the thermostat valve can go to flow or return

It doesn't matter if the TRV is fitted on the flow or return, but some valves are fussy about flow direction. The water flow through them should follow the direction of the arrow on the valve body.

Bi-directional valves, identified by a double headed arrow, can be fitted either way round on either flow or return
