I read conflicting reports on saving on heating.
One theory argues to close off all rooms that are not being used, heating only the rooms being used / occupied.
Others suggest leaving rooms open to improve air flow of the heating system.
And does it make sense to set the timer thermostat lower at night, letting it turn on early in the morning. I've read that it's best to set the thermostat and don't touch it.
I need advice and suggestions -
