What chimneys face in the 302 area
Geographically, 302 covers the entire state of Delaware, from Wilmington, Newark and New Castle in the north through Dover, the state capital, to Rehoboth Beach, Lewes and the other beach towns of Sussex County. Census figures count about 452,000 homes and apartments here. About 44% were built before 1980 (8.3% before 1940), and the median home dates from the 1980s. About 59% are single-family detached houses.
Wilmington, the most populous city in Delaware, lies where the Christina River and Brandywine Creek meet, near the Delaware River. It had 70,898 people at the 2020 census, is the seat of New Castle County, and anchors a metro division of 740,426 residents.
Winters are cool rather than harsh. NOAA's 1991–2020 normals for Wilmington New Castle Co Airport, DE show about 4,647 heating degree days a year, a January average of 33.5°F, and about 20.2 inches of snow. Rain and the occasional freeze still work on brick and mortar over the years, so a cracked crown or a missing cap is worth fixing early.
By Census count, about 42% of households heat mainly with utility gas and about 36% with electricity. Wood is the main heat in fewer than 2 in 100 homes, so most fireplaces here are for cool evenings, and gas fireplaces and inserts are common. It sits in IECC climate zone 4A. Wood, gas or oil, the NFPA 211 standard says chimneys, fireplaces and vents should be inspected once a year.
