Air conditioning systems are not yet a stock feature in households whereas every northern European home is built with a form of central heating. Virtually all new housing developments incorporate central heating systems as a regular fixture within the family.
Having become used to modern amenities we cannot do without a heating system. Heating your dwelling provides a relaxing and cosy atmosphere. The central heating system also can give you a cheap source of hot water. As heating and hot water are essentials your system needs to be dependable. You want to match the central heating system to your home requirements so that it both meets your requirements and uses gas efficiently.
You will find two primary system forms, vented and sealed central heating systems.
pumped/vented systems are the most familiar. A feed and expansion tank is incorporated into this type of central heating system alongside a hot water cylinder. Water expands when warmed and the expansion tank allows for this. The loft is most normally used to house the expansion tank as it needs to be high in the house.
Sealed central heating systems are now more usually installed in new homes. A sealed system, as the name suggests is a closed system so no water tanks are needed. The function of the water feed tank is now provided by the cold water mains. if you take this system you don’t need to use your loft for housing in the expansion tank thereby saving space, seaing the system and removing the need to vent the hot water has some benefits:
- no risk of freezing pipes in the loft
- no maintenance work on the tank or pipes that would be in the loft in a pumped or vented system
- less chance of leakages
- sealed systems do not see airlocks and the absence of air reduces the likelihood of inner corrosion
A sealed system accommodates fluctuations in pressure in the water supply by using a water pressure vessel. A safety valve will open if the pressure is higher than advocated. Similarly cold water is allowed into the system if the pressure is lower than the advocated level.
