Opinion sought on adding TRV's

[graham bowers]

My CH system has nominal 9.5 KW of radiator capacity and 13 radiators plus the indirect hot water cylinder through a diverter valve. All but 4 radiators have TRV's fitted. Those that don't are the downstairs toilet (0.29 KW) Hallway that has the system room stat (0.84 KW) kitchen (1.25 KW) and dining room (1.4 KW).

Radiator KW ratings are nominal catalogue spec just to give a sense of relative size.

The kitchen gets heat from cooking activity and the dining room picks up solar and has a computer that chucks out heat. These seem good candidates for TRV's as the missus and daughter tend to open windows if it gets too warm.

That would leave the hallway and downstairs toilet without TRV's at about 1.1 KW.

Any obvious snags with this plan please?

Nope sounds ok as you say leave the other two as they are

Thanks for that, padded to get to 20 characters

I’d do the downstairs toilet while you’ve got the system drained, that way every room is controllable by a thermostat.
