Several types of Central Heating Systems are available in the heating 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.
Whilst we need heating systems air conditioners are not needed in the United Kingdom and Europe because of the average temperature throughout the year. Most of us need a decent heating supply far more; this is why the majority of new houses that are being built in this day and age are built with a Central Heating System.
Central Heating is essential, particularly whens winter is heading our way. You can make your home more comfortable, pleasing and relaxing by heating it with Central Heating. This security in wintertime is possible only if your Gas Central Heating System is foolproof, well maintained and operating efficiently. You Central Heating System must give you the feeling of confidence that it is safe, simple to use with a long life.
Vented (or pumped) and Sealed heating systems are the two most common types available.
Pumped/vented systems are the ones that many homes have and they have the most components resulting in potentially higher maintenance costs. The pumped/vented Central Heating Systems have an expansion tank and a feed. Hot water from the storage tank supplies your kitchen and bath while also heating up the radiators. The tank makes way for any water expansion that is caused by the heating process. It is normally placed at the highest place of the house like the attic area, taking up space. It not only heats the house, but also supplies hot water.
A lot of older homes have pumped/vented Central Heating systems.
A central heating boiler system that is somewhat newer and more modern and that most people are choosing nowadays over the pumped/vented Central Heating system is the sealed system. 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.
- Frozen loft pipes are no longer a problem.
- No maintenance or repair work is required for the pipes and tank which would have been in the loft.
- The risk of leakage is decreased as there are fewer pipes and the system is less complex.
- Unlike pumped/vented systems, air is not drawn through open vents so the possibility of airlocks, corroding and sludge is much lower.
- Can be flushed out under pressure if needed by the mains 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 pressure of the main water supply benefits the hot water outlets and gives a healthy shower.
Normal variations of pressure can be allowed in a sealed system through a pressure vessel that contains compressed gas; this is separated from the sealed system water by a diaphragm. Pressure buildup in a Sealed system can be relieved by a safety valve which drains out water; and pressure drop is compensated by automatic fresh intake of water via another valve.
As compared to other heating systems, Gas Central Heating systems are cheaper to run. They offer you a lot more control of your home environment than the other heating systems.
