"The wrong way" would mean water flowing into the radiator through the balance valve and out through the thermostatic valve, but the radiator is symmetrical, and the valves are not one way (are they?), so what would be the problem? The reason this came up is I'm plumbing in a new radiator and I've not marked which pipe is which that I've threaded out of sight under the floor. Although I can actually tell which is which as it's HEP pipe with metre markings on it, I wondered if I really have to know? The online spec. for my valves says they can be used either way. In industrial pipework, the throttling valve is always put on the leaving side. -- Davey. |
