Boilers are often used to heat homes and have for decades now, delivering warmth and comfort even in the coldest months. But how exactly do these systems work? What are their main components? Whether you simply own a boiler or need to replace one and want to understand how boilers work, Ambient Heating & Air Conditioning will break down the systems of a boiler and how they work.
How Does a Boiler Heating System Work?
A boiler heating system is designed to heat water or sometimes steam and circulate it through radiators, baseboard heaters, or underfloor tubing to warm your home. Unlike forced air systems, which blow hot air into spaces, boiler systems radiate heat, providing even and consistent warmth. Following is how a boiler works.
• Water Source: The system starts with water, typically from your home’s main supply.
• Heating the Water: The boiler heats the water using various fuels. Common fuels include natural gas, oil, electricity, or even wood for older boilers.
• Circulation: Once heated, a pump circulates the water through a network of pipes leading to radiators or other heating outlets.
• Radiation: As the hot water flows through these outlets, they produce heat, warming up the surrounding air.
• Return Path: After releasing its heat, the cooled water returns to the boiler to be reheated and start the process again.
What are the Main Components of a Boiler Heating System?
A boiler is made up of a number of different components. Each component of the boiler has a role to play to ensure you have a warm home.
• Boiler: The heart of the system, is where water is heated. Modern boilers are more compact and efficient than their older counterparts.
• Burner/Fuel Source: This component introduces the necessary fuel like gas or oil and ignites it to produce heat. Electric boilers use heating elements, similar to large electric kettles.
• Heat Exchanger: Positioned within the boiler, this component assists in the transfer of heat from the burner or heating element to the water.
• Pump: This circulates the heated water through the pipes and into the home’s radiators or other heat systems that spread the heat.
• Expansion Tank: As water heats, it expands. The expansion tank compensates for this increase in volume, preventing potential damage to the system.
• Radiators, Baseboard Heaters and Underfloor Tubing: These are the heat distribution points. Radiators are the most traditional, while underfloor tubing offers a more modern, concealed approach.
• Thermostat: The system’s control point. It monitors the home’s temperature and signals the boiler to turn on or off accordingly.
• Safety Valves and Devices: These ensure that the boiler operates within safe parameters, releasing pressure if it becomes too high and shutting down the system in case of malfunctions.
