Determine what configuration of central heating gas boiler you need
There are a number of kinds of Gas Central Heating Systems on the market nowadays. Almost all these systems have a heating boiler at the core, with pipework connecting it to heating radiators.
In most parts of the UK air conditioning is hardly required because of the average temperatures of those regions. Many of us find proper heating a necessity; as a result most of the new homes being constructed today are built with a Gas Central Heating System.
Heating is vital, especially as wintertime is fast approaching. While blizzards rage on outside, you can be safe and warm on the inside. Therefore your heating system needs to be efficient and reliable. You Gas Central Heating System must give you the feeling of assurance that it is safe, simple to use with a long life.
There are two main types of Gas Central Heating Systems; pumped/vented and sealed systems.
The vented/pumped one is more common of the two. A pumped/vented Gas Central Heating System has a feed and expansion tank. Hot water from the storage tank supplies your kitchen and bath while also heating up the central heating radiators. The expansion tank has enough space to allow for the expanding of water as a result of heating. 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. The tank provides a dual supply of hot water and warmth for the house.
Older homes generally have pumped/vented Gas Central Heating systems.
A sealed system is now being used in the new houses that are being built. A sealed system, as the name suggests is a closed system so no water tanks are needed. There are benefits to have this closed type of system with pipework and tanks being unnecessary.
- The problem of freezing pipes is eliminated.
- As opposed to pumped/vented systems there is no need for maintenance work on tanks or pipes.
- Reduces the risk of leaking.
- As there are no open vents, air cannot enter into the system and so the risk of corrosion, air locks and sludge is drastically cut.
- Can be easily rinsed out under pressure via the main water supply.
This central heating system is self contained incorporating all the safety devices and other important controls. A sealed Gas Central Heating System uses water that comes directly from the main water supply. The mains water goes straight to the sealed system.
A pressure vessel containing tightly packed gas can allow a sealed system to have normal fluctuations of pressure; a diaphragm serves as a barrier between the gas and water in the sealed system. The pressure in a sealed Central Heating System is controlled by a valve that lets water out if the pressure becomes too high and opens to refill the system with water if the pressure gets too low.
Compared to any other form of heating, Central Heating systems are by far the most practical and economical. They also offer you all round control which is more than most heating systems do.
