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. **
