For your home

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

Pipes: watch the cold

Tonight’s low: 24°−4°

Overnight low near 24°F — not yet at drip-the-faucets cold, but worth watching if it's forecast to drop further.

Heating this week

About 62% less heating than a typical week.

This week 60Typical 159

Heating degree days, base 65°F

Heat-pump hours, next 7 days

h below 47°F: 44
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 6 hours are near freezing and damp, when outdoor units defrost more often.

Comfort

Dry air outside (dew point 25°F).

Open the windows?

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