For your home

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

Drip faucets tonight

Tonight’s low: 12°−11°

Overnight low of 12°F for 8+ hours — cold enough that pipes in unheated spaces can freeze. Let faucets on exterior walls drip overnight.

Heating this week

About 67% less heating than a typical week.

This week 58Typical 174

Heating degree days, base 65°F

Heat-pump hours, next 7 days

h below 47°F: 35
h below 17°F: 5
h below 5°F: 0

47, 17 and 5°F are the test points heat pumps are rated at. About 7 hours are near freezing and damp, when outdoor units defrost more often.

Cold-climate heat pump? Look up certified models on rebate.blue (opens in a new tab)

Comfort

Dry air outside (dew point 36°F).

Open the windows?

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

Is this typical?
