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

Pipes: watch the cold

Tonight’s low: 23°−5°

Overnight low near 23°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.

h below 47°F: 32
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 18 hours are near freezing and damp, when outdoor units defrost more often.

Comfort
