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

Pipes: watch the cold

Tonight’s low: 26°−3°

Overnight low near 26°F — not yet at drip-the-faucets cold, but worth watching if it's forecast to drop further.

Heating this week

About 67% less heating than a typical week.

47, 17 and 5°F are the test points heat pumps are rated at. About 2 hours are near freezing and damp, when outdoor units defrost more often.

Comfort

Dry air outside (dew point 27°F).

Open the windows?

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