Distilled water is just that, distilled, pure water. If you take tap water and boil it you will find a whitish buildup on the side of the pot or pan you boil it in. Now if you would have placed that same water in your furnace you would get that same buildup. When that happens in pipes it is called scale or scale buildup. When that happens you loss the efficiency of the furnace, it makes it harder to heat.

I would imagine it is because of the level of Ca & Mg (TDS) in potable fresh water. We have to use distilled (not de-ionized) water in our rectifier's cooling system to prevent the build up of Ca in the heat exchanger of the rectifier cooling water system.
FYI de-ionized water is extremely aggressive and will cause metal in the cooling water system to degrade.
