Just bled all my radiators in my house & all of them are chucking out very blackened/dark water. Most of them had little to no air them apart from the bathroom one which seemed to have enough air in it to fill a bouncy castle!!!!
Anyway, is this normal? Or should I drain the system out completely & refill it with again & add some Central Heating Inhibitor (1L)
btw, its a small 3 bedroom house with 9 radiators (4 downstairs), open system (with header tank in loft) & it was drain out 3 years ago when we had to move a radiator in the kitchen.
System is 15 years old.
Thanks in adavance!
