I flushed one radiator, and apart from a bit of rust coloured water....it did not seem that bad really. I will have to flush a few more to get a better idea.

This may be on the to do list in the future.....but for now....I am sticking with this. The boiler itself is only 7 years old. A modern condensing heat only boiler. I was considering that as an option, but the boiler is not the highest point of the system. Tank is in in the loft, boiler in the...

Yeh, A full bore lever valve on each end seems a doable/sensible solution if I want to make it easier to service. Just a bit more work to install. @Motman 's solution probably works just as well though. Although without cutting of the return pipe I wonder if there would be enough pressure to...

Ahh, I thought that makes it more difficult to flush and clean the magnet out, i.e you have to drain the system to clean it. But, looking at their videos, I assume this is the scenario sans valve: I assume another option is to fit my own 22m full bore valves before and after the filter.

After a bit of reading, should I be concerned that the valves on the Fernox Omega are not full bore? Will that cause issues with a open vent heat only system?

Looks like a good one, I think I have seen recommendation for that before. Looks easy enough to fit, might as well do it myself. From what I can see, it should be fit on the return pipe just before the boiler. As I have a heat only boiler, I assume I do not have to consider the location of...

Sounds like a good plan. I assume it is best to get the filter connected before filling and flushing the system at all? Any recommendation on filter brand? I know magnaclense crops up everywhere with marketing but what do people recommend on here? Or is it one of those "can of worms" questions.

I had to drain my Central Heating system down to remove radiators/decorate etc. Unfortunately it has been drained down for far longer than expected due to certain delays, 12 months now. I plan to flush each radiator manually before refilling, but should I be concerned about the rust that and...
