What Key West Does to a Tankless Heater

Space is scarce in Key West and the salt air reaches every surface. When a heater is tucked into a tight utility nook, corrosion on its fittings and vent cap is the first thing we look for.

Local factors in Key West

  • Coastal corrosion. Sea air attacks outdoor fittings and electrical connections, so we look for corrosion on every visit in this area.

Census snapshot

Housing in Key West at a Glance

14,414homes in total
1967typical build year
2%use gas heat
47%lived in by owners

Key West is mainly an electric-heat market, at about 84% of homes, which makes an electric tankless model a likely find; those units draw heavy current, so a fault often shows up at the breaker, an element or a temperature sensor. Half the housing here predates 1967, when homes were piped and vented for tank heaters; a tankless unit added later often needed a larger gas line, a new vent path or a condensate drain, and those add-ons are frequent starting points for a fault. Owner-occupied homes make up about 47% of the total and single-family houses about 52%, a mix that means tankless problems get reported by owners in some homes and by landlords or tenants in others.

At roughly 4,611 people per square mile (about 25,824 residents on 5.6 square miles), Key West is suburban in feel, with detached houses mixed in among townhomes and smaller complexes. Our Florida coverage list has 308 communities, and this one is number 92 among them by population.
