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

Heating this week

About 70% less heating than a typical week.

This week 39Typical 133

Heating degree days, base 65°F

Heat-pump hours, next 7 days

h below 47°F: 28
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 19 hours are near freezing and damp, when outdoor units defrost more often.

Comfort

Dry air outside (dew point 28°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?

Today, 2:00 PM–5:00 PM

Good stretch to open the windows (air quality forecast not available for part of this window).
