Replacing baseboard thermostats

[Josh Carpenter]

Hey everyone! I have two really grungy (though fully functional) baseboard heat-only thermostats, circa 1980. Similar to my previous question on Wi-Fi locks, what are people's experiences with modern thermostats? I've learned that it's a specialized type of line voltage thermostat, not compatible with regular low voltage Furnace/AC systems. I want it to be easy to use for guests, and allow me to set it remotely when the unit is vacant. Nest seems like a good bet, but it's not clear if they are compatible...? Thanks in advance!
