Should I worry about this or do the job properly and drain the system and swap them all round? Just do it! With the whole system off, no water could go through the 2 zone valves so it must have come out of the return pipes surely? The evidence of temperature differential is pretty clear now though. I thought I read that nowadays it doesnt matter which way round the TRV is on the Rad — in older ones you used to get a knocking if fitted to the return side inadvertently.
For good order I fitted all mine to the flow side though. They are first-party cookies and are used for core functionality such as allowing users to log in and storing basket contents.

Typically, the only moving part on the radiator is the valves that attach the hot water pipes to the radiator themselves. It is common for individuals to learn more about TRV, Manual and Lockshield valves and they generally hope to have these standard radiator valves explained so they know what to buy.
Here are terms you must know in order to make the best decision when selecting a radiator for your home or flat. In addition to this, learn about the different types of valves and find out which radiator valves you need for your home. The thermostatic radiator valve TRV is used in office and apartment buildings to provide zoned heating from a central boiler.
With a built-in temperature sensor, the TRV will automatically adjust the heat output from the radiator to help maintain a steady room temperature. The TRV may be angled or straight, depending upon how it must be connected to the radiator, and they are sometimes decorative, designed in antique brass, copper, or nickel. Balancing the output of heat is a fairly simple operation that you should be able to perform.
The manual valve controls the water flow into the radiator to provide a constant level of heat. You must adjust the heat by physically turning the valve. As it has no labeled settings, the manual valve is smaller and more discreet than the TRV and either angled or straight, depending upon how it must be connected to the radiator.
Manual valves by Evolve begin under two pounds fifty. If you find the coolant is flowing, it means the thermostat valve is open. Why are my radiators cold when the heating is on?
If the radiator is cold at the top and warm at the bottom it could be a case of having a trapped air bubble. When a central heating system is signalled to switch on, it sends hot water to radiators.
If the top half of the radiator is warm but the bottom half cold it usually means a sludge problem. How do you fix a radiator that won't heat up?

Leave them fully open, you have to have at least one rad permanently open so the pump can always push water round the system when it's on. Why is there 2 valves on a radiator? The reason you need two valves generally on all rads is because the system dictates a flow and return. The flow pipework carries the newly heated water from the boiler.
The return taking it back at a lower temperature to be reheated by the boiler. What are the two valves on a towel radiator for? There are two main types of heated towel rail valves.
