The house we moved into this year has Electric Baseboard Heating. It had six very basic thermostats and one of the classic round Honeywell thermostats that at least showed the room temperature.
Six of the thermostats are what is know as "Line Voltage" thermostats. 240 volts in my house. I replaced those with Aube (bought buy Honeywell) TH104Plus programable thermostats. (2 wire) They are fantastic!
5+2 programming, backlight, ultimate precision (± 0.15ºC / 0.27ºF)
3500 W @ 240 V, 14.6 A

The classic round Honeywell presented more of a challenge. It was also 2 wire but I measured the voltage and it was 29.5 volts. A web search didn't turn up much so I called Honeywell and, after some research, they recommended their RTH230B. It is listed as a 24 volt thermostat but the guy from Honeywell said the maximum voltage for that unit is actually 30 volts.
All of my thermostats are now 5+2 day programable and they all show the temperature. It is really nice waking up to a warm house and getting home with the heat coming on 15 minutes before I arrive. With the old old thermostats we were either hot or cold.
Temperature outside tonight will go down to -1ºC!
