Expansion tanks are used to control and stabilize pressure fluctuations caused by thermal expansion in closed-loop plumbing and heating systems. Their installation helps prevent damage, prolong equipment life, improve energy efficiency, and ensure the safe and efficient operation of these systems.
Pressure Regulation
One of the primary functions of an expansion tank is to regulate and stabilize the pressure within a closed-loop system, such as a hydronic heating system or a domestic hot water system. When water is heated, it expands, which can lead to an increase in pressure within the system. The expansion tank absorbs this excess pressure, preventing the system from experiencing potentially damaging pressure spikes.
Preventing System Damage
Without an expansion tank, the increased pressure caused by thermal expansion could lead to damage to system components, such as pipes, valves, and fixtures. In extreme cases, it can cause leaks, bursts, or even equipment failure.
Prolonging Equipment Life
By maintaining a stable pressure, expansion tanks help prolong the life of system components, reducing the risk of premature wear and damage.
Energy Efficiency
In heating systems, such as boilers or water heaters, expansion tanks contribute to energy efficiency. They prevent the relief valve from opening due to excessive pressure, which can result in water discharge and energy wastage.
Reducing Water Waste
In systems without expansion tanks, excess pressure is often released through a relief valve, leading to water wastage. Expansion tanks prevent this unnecessary water discharge.
