heating
In a thermoelectric generating system a heat source—usually fueled by coal, oil, or gas—is used within a boiler to convert water to high-pressure steam. The steam expands and turns the blades of a turbine, which turns the armature of a generator, producing electric power. A condenser converts any remaining steam to water, and a pump returns the water to the boiler.
Before the 12th century, indoor heating in Western Europe relied on central open fires, which required large roof openings that allowed wind and rain to enter and failed to effectively clear smoke.12
The introduction of the masonry fireplace and chimney significantly improved indoor environments in several ways:
- Smoke Removal: Unlike central hearths, chimneys efficiently carried smoke out of the building, preventing it from lingering and plaguing occupants.12
- Weather Protection: By eliminating the need for large roof openings, chimneys kept wind and rain out of the living space.2
- Architectural Flexibility: Chimneys allowed for the heating of both small and large rooms, as well as multistory buildings.2
- Increased Privacy: Because fireplaces could now be installed in individual rooms, houses were divided into smaller, more private spaces. This shift moved society away from the communal lifestyle of early medieval times, where many people shared a single, large, semipublic heated room.2
By providing a fireproof backstop and a dedicated flue, the chimney transformed domestic architecture and comfort.1
