You should set the temperature around 50to 60 degrees Fahrenheit (℉). Most of the time, dropping thethermostat to 50 °F to save some heating bill is fine. Youdon't need to set your thermostat too high if your plumbing runswithin the interior walls. You should have no issues byleaving the thermostat at 50 °F.
