What this week’s weather means for heating, cooling, pipes and fresh air.
About 71% less heating than a typical week.
Heating degree days, base 65°F
47, 17 and 5°F are the test points heat pumps are rated at. About 17 hours are near freezing and damp, when outdoor units defrost more often.
Dry air outside (dew point 27°F). Indoor air will run dry too — a humidifier keeping indoor relative humidity in the 30–50% range is more comfortable and cuts static shocks, without going so high it fogs cold windows.
Today, 2:00 PM–4:00 PM
Good stretch to open the windows.
Today’s expected high is 2°1° warmer than typical.
On average 1° colder than normal (daily mean temperature).
