heating system boiler maintenance

Iíve been wondering about water/mineral deposits in the piping that is used to carry the water in my heating system. It uses a boiler, and about 8 yrs. ago what I think was the original, was replaced. The original was a huge all cast iron monster. I had to break it into pieces with a sledgehammer. AnyhowÖ.
Iím curious about the deposits that end up getting left in the piping system that go all around the house, and in the convectors.
Wondering if there is something I can add and do to flush the system, maybe I get better heat, or 0.03 off my heating bill???

The boiler we put in is a higher efficiency, and is working fine, Iíd just like to maintain it and keep it in good working order.

Thanks!

The water in the system shouldn't be touched once it's operating unless you need to replace a component. As that water ages, it's gets better for the system. If the mfg of the boiler didn't specify any additives with the new install, don't use any.

That is pretty much what I was thinking. What about the "makeup" water though? I don't forsee it having to top off very often, but obviously new water is added if the level gets low. There is a sort of pressure switch, or mechanism on the system that will add water if it is needed.
I'm going off memory here, so I can picture the device so well.

Yes, there probably is a auto fill or pressure reducing valve on the system. A closed system shouldn't really need make up water, unless there's a slight leak.
