Hi I wonder if you can help me
All rads are cold, the Grunfos alpha 2 pump is running and all pipes around it are hot, there is a pipe behind it with a bleed vavle on the end, If I release the air from this pipe and mess around with the speed of the pump, start it and stop it I can get the rads to go hot for 10 to 12 hours but then they go cold so I go back to bleed air mess with pump speed until it goes again.
Any ideas what's causing this problem?
Any help appreciated
Thanks
