Does a small overnight setback pay off on a heat pump?
A modest overnight setback seems like it could reduce heat loss, but the morning recovery may call on auxiliary heat and eat into the savings. How much does that balance depend on the thermostat’s controls and the backup-heat setup?
For a practical comparison, would you first establish whether the system has electric or another type of auxiliary heat, and whether the thermostat indicates when it runs? What energy-use or runtime patterns would make a fair comparison between holding a steady setpoint and using a small setback, rather than mistaking a cold-weather or occupancy change for an effect of the schedule?
