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

Pipes: watch the cold

Tonight’s low: 22°−6°

Overnight low near 22°F — not yet at drip-the-faucets cold, but worth watching if it's forecast to drop further.

Heating this week

About 66% less heating than a typical week.

47, 17 and 5°F are the test points heat pumps are rated at. About 12 hours are near freezing and damp, when outdoor units defrost more often.

Comfort

Dry air outside (dew point 26°F).
