- flow return thermostatic valve
Discuss Thermostatic Valve, fit to Flow or Return? in the UK Plumbing Forum | Plumbing Advice area at PlumbersForums.net
It depends which valve you have , but most nowadays are bi-directional so it doesn’t matter.
However.
On a vertical rad quite often the direction of flow is critical - it should tell you this , but it doesn’t matter if trv is on flow or return.
