The householders guide to the primary types of home central heating systems

Central heating systems have improved and that there are now many different forms each with differing advantages and drawbacks according to your requirements. This paper will help you to picture the choices available to you. Most if not all of these Central Heating System comprise of a gas boiler, radiator and piping.

In the past central heating systems were rare and only added as an after thought to the homes of affluent consumers. Nowadays whenever you purchase a new property you will expect that it has an efficient central heating system, probably gas. Also it is rare that buying an already occupied property your find that it does not have central heating, if this is a situation you certainly will want to reflect its omission in the purchase price.

Heating is vital, particularly in wintertime. Arriving home to a cold property is not pleasant. The drama is completely transformed Wendy heating system is switched on creating a warm environment. Not only will a modern gas boiler power the central heating system but it is also able to produce hot water, whether stored or on demand, for use in bathing and showers or washing clothes or cutlery.

Whatever type of system you have chosen the overriding requirement is that is dependable and that you do not suffer unexpected breakdowns. Most people completely ignore their central heating and only pay attention when it stops working. We would suggest that a another very important aspect of a central system is that it is efficient.

Central Heating Systems fall into two main categories; pumped or vented and sealed systems.

The pumped/vented system is most frequently seen. This type of system has a feed system and and expansion tank in concert with a hot water cylinder. The expansion tank is placed high up in the house often in the attic. It allows water in the system to expand when hot and also conveniently tops of the water in the central heating system if any evaporates or you have a small leak.

These days the sealed system is the variety which is most often installed in properties. An advantage of a sealed system is that it has no requirement for an expansion tank. A sealed central heating unit will get its water supply direct from the mains at pressure. This frees your loft of the expansion tank and copper piping, you get a range of advantages from the elimination of these constituents:

– no chance of freezing pipes in the loft

– fewer elements require less upkeep

– fewer leaks from pipework joints

– reduced risk of air locks, corrosion and sludge as there isn’t a chance of air being drawn down into the system through open vents as the system is sealed

Variation in the water supply taken direct from the water mains is handled by a pressure vessel which is formed into the system. If the pressure becomes too high in a sealed Central Heating System; a safety valve will allow water to escape from the system and if the pressure drops too low a valve will open to replenish the system with water.
