I had a combination boiler (Baxi/Potterton) installed about 6 weeks ago. The
boiler seems to be working okay in terms of providing central heating and
hot water.

The problem is that the hot water provided by the boiler has a milky white
colour - to the extent that when the kitchen sink is filled with hot water
the water is completely white. I thought, initially, that the problem was
perhaps down to flux in the system or alternatively to limescale (I live in
a very hard water area). But I think something else is probably wrong. The
problem seems to be less apparent when the bath is filled with hot water and
more apparent when water is drawn from a sink.

Has anyone come across this before?

Is this anything to be worried about?
