Yes it does. They have a baffle or diverter near the flow. So it is imperative that the flow is connected to the inlet port ,and return to the outlet port.
What happens if you get flow and return the wrong way round?
If the pipes are reversed, the sensor will record the lower temperature and could compensate to make up the difference. This can result in unwanted noise, or overheating and inefficiency.

Yes. As it is at present the flow runs straight thru the bottom of the rad and out the other side. Water will follow the path of least resistance.
Does it matter what side the radiator thermostat go?
The vast majority of new TRV’s are bidirectional and can be fitted to either the flow or return, but it is always good practice to fit them to the flow side. If a non bidirectional TRV is fitted on the return side it will create a vibrating sound as the water tries to flow though it.
Are radiators on a loop?
Single pipe loop
Each radiator ‘sits’ upon the pipe with both radiator connections made to the same pipe. As the heated water from the boiler is fed along the pipe, natural convection (hot water rises) causes the heated water to rise into the radiator displacing cooler water back into the pipe.
What are the two pipes on a radiator?
The two-pipe system consists of – you’ve guessed correctly – two separate pipes: one that feeds hot water to the radiators and one that conveys used water back to the boiler. In other words, the radiators are installed in parallel.
Do radiators have a flow and return?
The hot water doesn’t remain in the radiator, instead the hot water flows through the radiator and out again to the next radiator in the chain. As the hot water flows through the system it starts to cool down. When it flows back to the boiler the water is in a cooler state, and the boiler then reheats the water.
