Heating this week

About 72% less heating than a typical week.

Heating degree days, base 65°F

Heat-pump hours, next 7 days

47, 17 and 5°F are the test points heat pumps are rated at.

Comfort

Dry air outside (dew point 24°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.
