A pressure expansion tank in a central heating system is a crucial component that helps to maintain the proper pressure levels within the system. As water heats up, it expands, and without a pressure expansion tank, this could lead to a dangerous increase in pressure within the system. The expansion tank provides a space for the expanded water to go, helping to prevent excessive pressure buildup. This helps to protect the system from damage and ensures that it operates safely and efficiently. **

Water pressure increases in a central heating system due to the expansion of water as it is heated. As the water is heated, it expands and the pressure within the system increases. This is why central heating systems have a pressure relief valve to prevent the pressure from becoming too high and causing damage to the system. Additionally, the pressure can also be increased by the use of a pressure pump to push the water through the system at a higher pressure. **
