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 32 hours are near freezing and damp, when outdoor units defrost more often.
Dry air outside (dew point 30°F).
No stretch in the next few days is comfortable enough outside, by temperature, dew point and air quality.
Today’s expected high is 7°4° colder than typical.
