Heating this week

About 71% less heating than a typical week.

Heating degree days, base 65°F

Heat-pump hours, next 7 days

h below 47°F: 27
h below 17°F: 0

47, 17 and 5°F are the test points heat pumps are rated at. About 14 hours are near freezing and damp, when outdoor units defrost more often.

Comfort

Dry air outside (dew point 37°F).
