I need a thermostat (simple mercury switch style) that goes down to 32F
or so, so I can heat a space only just enough to keep it from freezing.

So far, no luck.

Plan B is to just mount a regular thermostat, tilted, so as to skew the
temperature range. Just need the right night to calibrate it...

line or low voltage?

Freezing starts above 32 F when I needed freeze protection I chose 40F,
small safety margin.
