Which side to feed?

[ICanDoItWell]

I am replacing a bedroom single panel radiator with a double panel double convector because the previous rad was not sufficient. I also want to fit a TRV, there was none fitted before and with the larger radiator it is now needed.

Lots unexpected problems have been delaying this, such as plaster falling off a wall and a wall practically unsupported on floorboards due to cement breaking out over the last 46 years. The house is very cold so I need to get it finished quickly.

The left side of the rad is on a wall less than 3 feet from another wall at right angles so it is very close to a corner and I plan on putting a bed next to the rad which would box in a TRV quite badly. I therefore want to put it on the right hand side where it will have more air flow and be less restricted by the bed.

The new Rad is slightly wider too, 950 compared with 1m so pipework needs to be changed.

Here is the issue. The feed is usually on the left where I intend having the lockshield valve and the TRV on the right, closer to the centre of the room.

The TRV is bi-directional. Should I put the feed pipe to the left where the lockshield valve will be or the right with the TRV? Go with convention for piping, feed to the left, but have the lockshield valve on the feed side or have the feed on the right with the TRV?

TRV is Bi directional,either side will do

Yes, I know it's bi-directional, I did mention that for a reason. However, it's a question of whether I go with convention for feed and return but have the lockshield on the feed side or go against convention and have the lockshield on the return side like logic dictates.

I realise that it will work either way but I was thinking about people who might come to work on it later. It is going to be a bit confusing either way, but which is less so?
