We have a copper hot water cylinder which is 11 years old. For the past while there have been 'bits' coming out in the water - mostly noticable when you fill a bath. I got a friend to empty and flush out the cylinder (without disconnecting it) and it did help but now its back .. it has been flushed a few times now and I'm getting really fed up with it. The 'bits' are black pieces in the water - some very tiny but now this evening bigger bits.
So now I'm thinking it must be the cylinder disentigrating ???
And I am thinking maybe I'd be best replacing it to finally solve this ... I started reading a bit on here and see Stainless Steel cylinders recommended.
So I have some questions - should I replace the cylinder? Or do I need to?
If so then should I go for a stainless steel one?
I looked for prices but am not sure which stainless steel one I'd need ... I'm not sure on size - it was a "standard" size back then .. how many coil cylinder do I need .. I think 2 as I have a "Willis" heater installed which quickly heats a smaller amount of hot water so I think it must have 2 coils??? .. And can someone explain heat recovery also or is that just for solar?
Sorry for so many Qs - just want to see if its feasible for us to change .. or if its needed
Thanks in advance
