Hi
Just looking for some suggestions on what to look for/try next.
Up until last weekend, our oil fired boiler central heating was working fine, all radiators heating as required.
We then had an issue of a mouse deciding to go for a exploration in our air intake and causing it to begin to soot up on Sunday.
We had an engineer out on Tuesday to diagnose the mouse situ and give the flue a clean out. That problem was then fixed, but now we have quite a weird issue of some radiators not heating up. Downstairs, we have 7 radiators and a towel rail, only 4 of which are heating up. Upstairs we have 5 radiators, and only the 1 in the shower room is working. Location wise, there doesn't seem to be a clear logic on which ones heat up and which ones don't as the one closest to the boiler upstairs isn't heating up.
After completing the repair, the engineer did say to top up the pressure as it was just below 1bar. We done this today to around 1.4bar and the radiators still weren't heating.
We have bled all the radiators, and double and triple checked them, still to no avail. We then followed guidance from a YouTube video on balancing the system, all the valves were fully open, so closed them then opened half a turn, no change.
Any suggestions on other things to look at/for?
