A sealed Central Heating System is a packaged unit with all the necessary controls and safety devices. The sealed system gets its water through the main water supply at pressure. It feeds directly from the main water supply.
Normal variations of pressure can be allowed in a sealed system through a pressure vessel that contains compressed gas; this is separated from the sealed system water by a diaphragm. A safety valve will let water to escape or fill up depending on whether the pressure becomes too high or too low respectively.
