Should I lower my heat pump temperature at night?

Lowering your heat pump thermostat temperature by a few degrees at night can help save energy, but you must exercise caution to avoid triggering auxiliary electric resistance heating strips. Unlike traditional fossil fuel furnaces that can blast high-temperature air to reheat a home quickly after a large temperature setback, standard heat pumps deliver moderate warmth. If you lower your thermostat too much overnight—such as dropping it by five to ten degrees—the heat pump will struggle to recover in the morning, forcing the expensive backup auxiliary electric strips to engage and consume excessive electricity. Therefore, minor nighttime setbacks of two to three degrees are generally acceptable, or maintaining a steady, comfortable temperature around 68 degrees Fahrenheit is often more efficient. You can verify the best setting by monitoring your monthly utility bills.
