Electric Heat

[Jimmy7]

I have to replace an old mechanical 240 Volt 22 Amp. wall mounted electric heat thermostat. As long as I install another 240v 22 amp mechanical thermostat I’m good to go, correct? I didn’t know if I should be looking at anything else as well.

Match the 1p vs 2p option. Otherwise, you're good.

Are you referring to whether the thermostat breaks one leg of the 240V, or both legs?

Yeppers.

Just for completeness, the only gotcha would be if it's set up with a switch loop rather than line and load in the T-stst box, AND you are using one of the fancier electronic/programmable thermostats. Some of those t-stats don't work with switch loops or have specific heater requirements, such as no fan heaters.
