Steam heating is a method of heating buildings using steam generated from boiling water. In this system, water is heated in a boiler, and the steam produced travels through pipes to radiators or heating units in different rooms. As the steam cools, it condenses back into water and returns to the boiler to be reheated. This type of heating is efficient and can provide consistent warmth throughout a space. Steam heating systems are often found in older buildings but can still be effective in modern settings. Regular maintenance is important to ensure the system operates safely and efficiently.
