Trying to help my folks figure out what to do with heat in their house. Two story home in cold climate, 30 year old electric baseboard heaters.

Can I replace only the living room thermostat - or do I need to do all at once?

  • Why would replace the thermostat ? Is it faulty ? Nov 15, 2023 at 6:19
  • I've answered your question but I feel like there's another question or plan in the background which you might want to also post. If the goal is to reduce heating costs, a more intelligent thermostat can help a little, but it's going to be on the order of a few percent at best. Almost certainly the better way to go will be by adding mini splits.

Go for it. One of my friends has had to replace one of their baseboard thermostats twice while the other two are the original 1980s units. Unless this is a very weird system, there's no connection between the thermostats. Be aware that these will be 'line voltage' thermostats, so if you're thinking of using a smart thermostat it almost certainly won't work.
