Minimum temperature in unused room?
We live in a townhouse. No central heating—each room has its own electric baseboard heater and thermostat. Two of our rooms will be little used over the winter. Is there a recommended minimum temperature to set the thermostats at? I keep reading 15º but that is for an entire house with central heating and pipes that could freeze. There is no plumbing in either of these two rooms nor in the walls adjacent to them. If we shut the heat off entirely the rooms may drop to 12º or so. Is that ok? I've seen how paint peels in abandoned buildings that are unheated over the winter, I'm guessing that's not a concern with 12º?
