What is a TRV on a radiator?
Keeping this in view, how does a TRV work on a radiator?
The TRV is a valve that self-regulates, meaning it adjusts the flow of water into your radiator depending on the setting. And as the room temperature changes, the valve head expands, adjusting a pin in the valve body so that it opens or closes.
Also, what side does a TRV go on a radiator? 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.
One may also ask, do you need TRV on all radiators?
You should have thermostatic radiator valves (TRVs) on all radiators but not in the same area as a wall thermostat, it is possible that this room may never get warm enough to turn the boiler off via the wall thermostat if the temperature in this area is being controlled independently by a TRV.
What should radiator valves be set at?
It's not possible to precisely convert the scales of your thermostatic radiator valve to degrees Celsius.
Approximate conversion into degrees Celsius.
|Valve position||Reference temperature||Recommended setting for|
|3-4||20-21°C||Lounge, child's bedroom|
|5||max.||Valve completely open|
