The primary variants of the central heating system are sealed systems and pumped systems.
Expect to find a pumped/vented central heating system as they are the most familiar. A pumped or vented Central Heating System has a hot water cylinder and a feed and expansion tank. Hot water expands and in this type of system flows back to the expansion tank. The attic is most usually used to house the expansion tank as it needs to be high in the house.
A slightly newer, more present-day system that many people are choosing over a pumped or vented central heating system is a sealed system. There is no need for the water expansion tank if you choose to have a sealed central heating system installed. The mains water is used to supply the sealed Central Heating System. There are no tanks or copper piping in the loft, the sealed nature of the system without any venting delivers a number of benefits:

- less piping and joints to leak
- as the system is sealed there is less chance of air introduction leading to corroding or air locks
Any water pressure variations are accommodated by the incorporation of a pressure vessel. A safety valve will open if the pressure is higher than recommended. Similarly cold water is allowed into the system if the pressure is lower than the recommended level.
