Air conditioning systems are not yet a frequent feature in homes whereas every northern European family is built with a form of central heating. The majority of new houses that are being built in this day and age are built with a Central Heating System.

The value of central heating systems is fully realised in wintertime although most are also used to supply hot water every day of the year.

There are two primary variants of Central Heating System; pumped/vented and sealed systems.

Expect to find a pumped or vented central heating system as they are the most common. This type of system has a feed and expansion tank in concert with a hot water cylinder. In addition to allowing for water expansion when heated the expansion tank also tops up the central heating system with water when necessary. The loft is most normally used to house the expansion tank as it needs to be high in the house.

If you get a new home you may now find that it contains a sealed central heating system. A sealed system, as the name suggests is a closed system so no water tanks are needed. A sealed Central Heating System is connected to the mains water supply to allow the removal of the water feed tank. The loft is not now used for the expansion tank or copper copper piping, the whole system is sealed, its unvented, which has its benefits:

- you don’t need to worry about pipework in the loft freezing

- no maintenance work on the tank or pipe work that would be in the attic in a pumped or vented system

- less chance of leakages

- the sealing of the system precludes air entering which could lead to internal corrosion or the development of an air lock

A sealed system accommodates variances in pressure in the water supply by using a water pressure vessel. If the pressure becomes too high in a sealed Central Heating System; a safety valve will permit water to escape from the system and if the pressure drops too low a valve will open to refill the system with water.
