Hearth & brick

Ancient – 1790

Repairability: High

Open fires, brick ovens, and communal bake houses. Wood or coal required constant tending.

Cast iron stoves

1795 – 1900

Repairability: Medium

Enclosed cast iron directed heat to multiple pots and warmed the room — often too large for small kitchens.

Average lifespan

Decades with maintenance

Gas & early electric

1802 – 1920s

Repairability: High

Gas valves allowed flame control; electric resistance ovens followed once homes had wiring.

Average lifespan

NAHB gas 15 / electric 13 yr (modern baseline)
