Central Heating systems come in various forms. A heating boiler, central heating radiator and pipework are common components in many of these Gas Central Heating Systems, they are simple in plumbing terms.
Air conditioning is not a priority for residents of Europe and northern countries as these regions experience cold weather most of the year with short duration summertimes. Most of us need a decent heating supply far more; this is why the majority of new homes that are being built in this day and age are built with a Gas Central Heating System.
With the onset of winter, heating becomes crucial to warming your home. While snowstorms rage on outside, you can be safe and warm on the inside. For this, you need a reliable boiler in your Gas Central Heating system. It is essential to have peace of mind that your Gas Central Heating System is not only practical to use but also safe.
Two kinds of Gas Central Heating Systems are mainly in use; pumped/vented and sealed systems.
Pumped/vented systems are the ones that many homes have and they have the most components resulting in potentially higher maintenance costs. An expansion tank is present in a pumped heating system. Your heating radiators are heated and your water is stored in a hot water tank. Water expands when heated; this expansion is accommodated in a feed-expansion tank. The expansion tank is placed at highest spot to help create water pressure. It not only heats the house, but also supplies hot water.
A pumped/vented Gas Central Heating System is what most homes probably have, especially those built many years earlier.
A Sealed Central Heating System is a relatively modern technology, and is being adopted by many homeowners today. No water tanks are needed for a Sealed system as it is a completely closed setup saving space. This unvented system eliminates water tanks and loft plumbing, thus giving a number of advantages.
- There is no risk of pipes freezing in the loft as with older systems.
- attic space is freed up and pipe maintenance is reduced.
- The risk of leakage is diminished as there are fewer pipes and the system is less complex.
- The risk of air locks, corrosion and gunk are reduced because there won’t be any air being taken down into the system through the open holes as the system is sealed.
- The mains water supply can flush the sealed system if needed.
This central heating system is self contained incorporating all the safety devices and other important controls. The sealed system gets its water through the main water supply at pressure. There is no hot water tank, so water is drawn directly from the main supply.
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. A safety valve will let water to escape or fill up depending on whether the pressure becomes too high or too low respectively.
Central Heating Systems are worth the money as they are cheaper to run than any other form of heating. They also offer you all round control which is more than most heating systems do.
