dirty hot water All aspects of plumbing questions and answers, help, tips and information

[K.YOUNGS]

My hot water contains small dark bits of scale or something like.
Ive got a back boiler supplying a indirect cylinder.Ive got an idea that the heating coil in the cylinder might be on its way out,or some kind of corrosion inside the cylinder.Any ideas are appreciated. :?

Found cold water tank was covered with an old piece of chipboard,which had rotted & partially collapsed into tank. Chips of wood had then found their way into hot water cylinder,hence dirty hot water.Hope this is of help to others.

It could be the heating coil in the cylinder is corroding and the heating water is leaking into the hot water.

Check for a drain point on the cylinder, you could run the hot water off - drain the cylinder and refill a couple of times, to flush it. It could just be a build up of silt in the bottom of the cylinder - with the age of the system.

Has any water mains work been carried out in your area recently ? could just be some dirt has getting into the water supply and into your cylinder.

Tanks and cylinders are fairly expensive, so if you're thinking of renewing. It's best to think about the age of the boiler and the possibility of future breakdowns and costs. It may be best upgrading to a Combi boiler. It could save you abit of money regarding repairs and your gas bill.

Hope this helps
