How cold is cold?

Last year I moved from Yorkshire to Alice Springs. One unexpected
challenge was finding that removing blood stains from clothing became
difficult. A long soak in cold water doesn't work any more. Why? Is
Australian blood different?

The answer seems to be that the cold water is different - it isn't
actually cold. The warm climate means that the water in the tank, is
similarly warm.

Pager does not refer to the temperature of the water on the cold water
cycle. Was it cold, as it would be in Yorkshire, or tepid, as in Alice
Springs? It costs more to use hot water - perhaps this otherwise neat
piece of research should be repeated in colder climes, including a check
on the water temperature, before we all turn up the heat.
