What this week’s weather means for heating, cooling, pipes and fresh air.

Heating this week

About 71% less heating than a typical week.

This week 60Typical 204

Heating degree days, base 65°F

Heat-pump hours, next 7 days

h below 47°F: 45
h below 17°F: 0
h below 5°F: 0

47, 17 and 5°F are the test points heat pumps are rated at. About 21 hours are near freezing and damp, when outdoor units defrost more often.

Comfort

Dry air outside (dew point 19°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.

Open the windows?

No stretch in the next few days is comfortable enough outside, by temperature, dew point and air quality.
