Hi all,
I have a valliant eco pure 25kw system boiler, 210l valliant unvented tank and 12 radiators in a three story house.
The radiator in our loft extension on the second floor hardly gets warm, but the towel radiator in the en-suite literally 2 feet away is red hot. The radiator does not have a trv valve so the pin isn’t stuck.
The system has been bled and there is no air in the system. I have switched all of the trvs off then the radiator is red hot.
I have previously run x400 and x800 in the system on different occasions to clean the system out and have a magnetic filter fitted.
There is also another radiator close to the boiler that is always cold. The radiator has been changed along with the valves but this has made no difference. I suspect the pipe is blocked is there any way to unblock the pipe without having to pull the floor up to cut and replace pieces of pipe?
Thank you for any advice in advance!
