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

Heating this week

About 67% less heating than a typical week.

Heating degree days, base 65°F

Heat-pump hours, next 7 days

h below 47°F: 30
h below 17°F: 0

47, 17 and 5°F are the test points heat pumps are rated at. About 13 hours are near freezing and damp, when outdoor units defrost more often.

Comfort

Dry air outside (dew point 37°F).
