A heating system is a setup designed to maintain a comfortable indoor temperature during cold weather. It typically includes components like a furnace, boiler, or heat pump, which generate heat, and a distribution system, such as ducts or radiators, that spreads the warmth throughout a building. These systems can be powered by various energy sources, including electricity, natural gas, or oil. Regular maintenance is essential for efficiency and safety, ensuring that the system operates effectively and reduces the risk of breakdowns or hazards. Proper insulation also plays a crucial role in enhancing the performance of a heating system.
