I've looked around this and other forums but have not found a discussion matching my issue. We have recently had a new extension to the house and as part of that a new radiator has been added to the system, in fact 3 New ones have. The problem lies with the new one in the kitchen, the others are working fine.
The radiator rarely heats up and never to any great temperature, however the pipe below the valve on the 'output' side is hot, as hot as the working radiators. The pipe below the input valve, the one with the thermostat, is cold.
Any ideas as to why this is, could the valves have been placed on the wrong sides!? Any advice is welcomed. Thanks.
