I have a 2 story home with 2 heating units (1 for each floor).
My living room is open to the 2nd floor.
When I heat the downstairs, the upstairs become significatnly warmer (i know hot air rises, duh)... but I'm assuming this uses a lot more energy to heat the downstairs. Also, it becomes to hot for those in bedrooms upstairs.
Example: downstairs thermostat is set to 71, upstairs is set to 68. The tempreture upstairs is always over 71 when downstairs reaches 71.
Is there a best practice for energy conservation in heating spaces like this?
What would you set each thermostat to?
