Having more problems with CH/HW and wonder if there's any advice (it really would be appreciated as I'm rapidly losing hair!)
Two weeks ago I filled my central heating system with Salamander FastCleanse cleaning agent. Yesterday, I drained the system and flushed it for an hour or so from the header tank, and that's when the problems started. I now cannot get the upstairs rads to refill. I also noticed this morning, that the hot water is only warm.
Now, my system is a Baxi Bermuda where the boiler is behind the fireplace, and the hot water needs to be on in order for the C/H to be on. The downstairs rads are steaming hot (I assume because there is no circulation to upstairs)
Anyone any ideas why my upstairs rads won't fill up? I thought they would fill from directly from the header. Does this indicate a blockage? If so, how do I find/clear it? Also, why would I be out of H/W?
Any advice would be greatly welcomed. Thanks for reading Steve.
