Planning to use Fernox restorer then inhibitor in my CH system which is of the open vented variety. Property is a top floor flat, with microbore pipes running underfloor to rads. I have a pump on the output side of the boiler.
How best to "flush" the system until water runs clear, as per directions on the bottle?
Presumably I will have to open a rad union and collect the water there during the flush, but this will never completely empty the circuit because of the underfloor pipes?
do I need a powerflushing unit? what is a powerflushing unit? can I just run the pump to give me a "powerflush"?
