I'm a snowbird and worry about a furnace failure while I'm away. I've heard
that there is a temperature sensing switch that will turn on a lamp if the
house gets too cold. I'd like to set a lamp in the front window so my
neighbor can check the place as he drives by without coming inside. Does
such a switch exist? Who sells it? Thanks in advance.
Just buy a 120 volt thermostat like this one:
(Amazon.com product link shortened)
and wire it in series with the lamp.
Course if the cause of no heat is a power failure, then you're not in
very good shape, are you.
For a little more money you can buy low temperature alarms which will
dial a phone number, maybe your heating contractor, and deliver a message.
One of my relatives just installed this one from Home Depot:
He plugged some sort of strobe light into it so that the neighbors are
sure to see it. He said it worked fine except that it went off once
(while he happened to be in the house) - apparently the result of
plugging it into an outlet on an outside wall, which made the unit too
cold. So he plugged it into an interior wall and ran an extension cord.
I was going to get one for the house I've been trying to sell, but as of
1PM today it became no longer my problem, hurray.

Not to keep the house warm - but as a FAIOLSAFE indicator. If the
light is ON, there is both heat and power. If the light is off, either
the heat or the power is out, OR the bulb has failed.
It can give a false error indication, but is pretty well impossible to
produce a false "OK"
