A crucial component in closed-loop heating and cooling systems, this device accommodates the volume changes in water caused by temperature fluctuations. As water heats, it expands, and without a designated space for this increase in volume, the system pressure would rise significantly. This rise could lead to component failure or even rupture of pipes. The device provides a reservoir to absorb this extra volume, maintaining a stable and safe operating pressure.
Maintaining system integrity and efficiency are primary advantages. By preventing over-pressurization, it safeguards boilers, pumps, and other sensitive elements from potential damage, extending their lifespan and reducing maintenance costs. Furthermore, stable pressure allows for consistent system performance and optimized energy usage. Historically, open systems vented excess pressure directly, leading to corrosion and water loss; the enclosed design is a considerable advancement.
