Central heating is an engineered system designed to distribute thermal energy to an enclosed structure, such as a dwelling or commercial building. These systems typically involve generating heat via a centralized source, often using fossil fuels, electricity, or renewable energy sources, and then transporting that heat through a network of pipes. The heated fluid, which may be water or specialized heat transfer medium, circulates to various endpoints, such as radiators, underfloor coils, or vent registers. Modern implementations also include high-efficiency heat pumps, which utilize thermodynamic principles to transfer ambient heat into the structure, thereby improving energy efficiency and reducing reliance on direct combustion sources.
