Re: Rads not heating up
you will need to flush each rad in turn, turn all reds off except 1 flush that out for 5 to 10 mins then close it and move to the next if you are going to use sludge remover then put in in 3 or 4 days before you flush the rads out this is so it gets round the system and has time to work, if you have the spare time then this is ok but if you dont have the time its better to get the power flush done
