What would happen if you put the flow & return on opposite?
Would it still work properly?
Thx all

on a rad you mean, yes, just the same, on the boiler, no, the stat will be reading the wrong side,and the pump will be going the wrong way,,  |

Rocket it's also worth noting :- Thermostatic rad valves (certainly Dandfoss ones) are installed/positioned differently depending if fitted on the flow of return side.

like endfeed says, most TRY's can go either way, they're called bi-directional, you can tell because they have an arrow pointing in the direction of the flow, if there are 2 arrows, pointing both ways, its Bi-directional, it there's only 1 arrow, then that must go on the flow otherwise it knocks when it trys to shut off, the valve wants to close but the power of the pump fights against it and causes knocking which transmits all over the house,
