Tado TRV issue!?
Hello, I’ve recently had a radiator replaced including the valves. The TRV has been mounted on the return side of the radiator and not the flow side. The valve is bi-directional. The issue I’m having is that when heat is called for, it takes a very long time for the radiator to get hot and the valve where the TRV is mounted remains lukewarm. Is this a case of the new valve not opening fully!?
