Why is there "sand" in the pipes?

Plumbing puzzle: my neighbor has what looks like find sand which collects in her *hot water* eventually clogging metal screens on faucets, etc. The obvious answer is that this is some sort of mineral precipitate as the system has been flushed several times and a filter installed on the water coming into the house. What is causing this precipitate in the hot water and why doesn't this happen with my hot water which is the same town water on the same street (same pipes) that is going into her house?

Also, the water heater is from tank heated by a closed loop off the hot water furnace. The problem was occuring before this water heater was installed.
