One of the best ways to save energy and water with central heating and domestic hot water temperature is to install a programmable thermostat. This allows you to set specific temperatures for different times of the day, reducing energy usage when you don't need as much heating or hot water. Additionally, insulating your hot water pipes and water heater can help to reduce heat loss and save energy. Finally, regularly maintaining your heating system and water heater can ensure they are running efficiently, saving both energy and water. **

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. **
