Various types of Central Heating Systems are available in the market. These systems for the most part are made up of a number of central heating radiators, pipework and of course a gas gas boiler.
Due to the average temperature that is seen across the UK and northern Europe , people barely find the need for air conditioning. Many of us find proper heating a necessity; as a result most of the new houses being constructed today are built with a Gas Central Heating System.
As autumn fades and chilly winds begin to blow, homeowners turn to their Central Heating for warmth and comfort. A well heated house can help create a comfortable space for you to enjoy with your family. Your Gas Central Heating System needs to be reliable. It is important to have peace of mind that your Gas Central Heating System is not only practical to use but also safe.
Two kinds of Central Heating Systems are mainly in use; pumped/vented and sealed systems.
You will find pumped/vented systems in most homes at the moment. An expansion tank is present in a pumped heating system. The tank supplies your house with hot water and provides the radiators with heat. When the water expands as it is heated the expansion tank allows for this. A pumped/vented heating system requires that the tank be installed at the highest level within the house – such as an attic or loft space, certainly on the top floor. It not only heats the house, but also supplies hot water.
Most houses, especially the old ones will have a vented/pumped heating system.
A Sealed Gas Central Heating System is a relatively modern technology, and is being adopted by many homeowners today. As the name indicates, a sealed system is a an enclosed system therefore no expansion water tanks are needed. In the absence of water tanks and pipework, the whole system is sealed and vented; here are some prominent benefits of such a system.
- There is no risk of pipes freezing in the attic as with older systems.
- loft space is freed up and pipe maintenance is reduced.
- Because the system is not vented, there is less chance of water leaking out.
- Unlike pumped/vented systems, air is not drawn through open vents so the possibility of air locks, corroding and sludge is much lower.
- Can be flushed out under pressure if needed by the mains water supply.
All the required controls and safety devices are incorporated into the sealed Central Heating systems. The water for a sealed Central Heating System is supplied direct from the main water supply. The mains water goes direct to the sealed system.
A pressure vessel containing compressed gas, which is kept separate from the sealed system by a diaphragm, is used to allow any pressure variations. A safety valve will let water to escape or fill up depending on whether the pressure becomes too high or too low respectively.
Gas Central Heating Systems are a worthwhile investment as they have the lowest cost of operation when compared with other types of heating. They also provide you with complete control which is much more than other heating systems can say about themselves.
