Hi,
I have added a new rad to an existing pressurised system. I had to run the 15mm pipe 10' upstairs to cut into the existing pipes as I could not dig the floor up to reach the downstairs rads.
I have T'ed into the flow and return feed to a rad upstairs.
The problem is that the new rad does not heat up. I have bled the system, nice and clean water and the TRV and lock valves are both open. Is my problem that the heat will not flow downstairs? And if so how do I fix it.
When bleeding the system the pipes became hot but then cooled down. I have shut off the rad upstairs that I have T'ed into but still no heat in the new rad.
I have also repressurised the system.
Any tips/ideas much appreciated
