The idea of raising your thermostat is a good quick step with *no*
changes to habits (well except teaching folks to test the water temp
before being immersed in it a good practice anyway) personally I
like a *really* hot shower.... and wouldn't tolerate a "scaldproof"
adapter.

I think a small usage change will do you better with less
investment. Can you convince the family to stagger the washups? some
in the morning, some at night, some in the afternoon?
