For your home
What this week’s weather means for heating, cooling, pipes and fresh air.
Heating this week
About 72% less heating than a typical week.

47, 17 and 5°F are the test points heat pumps are rated at. About 8 hours are near freezing and damp, when outdoor units defrost more often.
Comfort
Dry air outside (dew point 30°F). Indoor air will run dry too — a humidifier keeping indoor relative humidity in the 30–50% range is more comfortable and cuts static shocks, without going so high it fogs cold windows.
