What this week’s weather means for heating, cooling, pipes and fresh air.
About 76% 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 23 hours are near freezing and damp, when outdoor units defrost more often.
Dry air outside (dew point 25°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.
No stretch in the next few days is comfortable enough outside, by temperature, dew point and air quality.
Today’s expected high is about typical for the date.
On average 5°3° warmer than normal (daily mean temperature).
