When you're used to deal with steam, that's not such a big deal when the system "fails" and starts providing hot water.
My (off-topic ?) question was more about cheese layers. From my point of view, removing paper strips (in order to "improve" the system) was just putting a big number of cheese slices in a "fail-unsafe" (by definition) computer. Hence the big loss of capacity when there's one squawk too many.
