I have ended up installing a new vertical radiator and placing it in a horizontal position in a conservatory. The reason for this was that the pipework would have looked ugly as it would have to go around a single step so I decided to place it in another part of the conservatory but in a horitzontal position. The entry point of the pipework to the radiator is hot but most of the radiator remains cold? There is no air in the radiator.
Why would you spend £££££££'s on an expensive vertical rad and put it sideways, you could buy a normal rad for less than half the price ? Some of those high rads have an internal tube that goes to the top, or in your case to the side and if its not piped up right will not work, that could be the problem or it could just be air locked, try turning off all the other rads and see if that gets it going,
Lockshield valve open, & not closed, & as mentioned above. Is there any bleed valve in radiator you can vent any air.
Valve is open and water comes out when I bleed. If I connect the radiator the other way round would that do the trick?
