I have heard of an anti-scalding device that can just screw into a kitchen
faucet. If this device exist, I could use it. Does anyone know of a web
source where I could perhaps find one?

I see someone has already suggested turning down the water heater. For
what purpose do you need to maintain water that is hot enough to
scald? You mention a kitchen faucet, which suggests either dish- or
handwashing to me. Of course it's nice to have a near-boiling water
spigot for coffee and instant soup, but those are usually add-ons, not
OE.
