Does it make a difference which side the feed goes on a rad

Hi,

Does it matter which side the feed is connected to on a radiator. I assume that the thermostat valve is always fitted on the feed side is this correct or doesn't it matter.

Doesn't matter. Traditionally it has been the right hand side. Most importantly is whether the trv is a 2 way valve or one way. If 2 way it doesn't matter which way the water flows.

If one way it has to flow in the direction of the arrow stamped on the valve body.

Always better to put trv on flow pipe into rad even if bi-flow.. As g4y has already said it does not matter which side is the flow
