Gas Boilers Information

Dwellings have different types of central warming

There are various kinds of Central Heating Systems that can be purchased in the market. A central heating boiler, radiator and pipework are common components in many of these Central Heating Systems, they are simple in plumbing terms.

People in the United Kingdom, Europe and some parts of Russia, hardly need an air conditioner because of the low average temperature. 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.

With wintertime coming up round the corner heating should be at the front of your mind. Only then you can relax and feel cosy inside your home. Your Gas Central Heating System needs to be reliable. A good central heating system should inspire confidence, give value for money and be simple to operate.

There are two main types of Central Heating Systems; pumped/vented and sealed systems.

The most commonly used systems are pumped/vented Gas Central Heating systems. A pumped/vented Gas Central Heating System includes components known as a feed and expansion tank to allow for the expansion of water as it is heated in the radiators. Hot water from the storage tank supplies your kitchen and bath while also heating up the heating radiators. When the water expands as it is heated the expansion tank allows for this. The tank is placed in the highest place, normally the loft area. 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 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. No water tanks are needed with the sealed system. This unvented system eliminates water tanks and loft plumbing, thus giving a number of advantages.

- There is no risk of pipes freezing in the attic as with older systems.

- loft space is freed up and pipe maintenance is reduced.

- The risk of leakage is cut as there are fewer pipes and the system is less complex.

- Reduced risk of airlocks, 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.

- The main water pressure can easily be used to flush out a Sealed system for easy upkeep.

A sealed Gas Central Heating System is a system with the required controls and safety equipment all contained in one. The mains water supplies the water required for the sealed Gas Central Heating system. It feeds directly from the main water supply.

The system also has a pressure vessel which contains compressed gas, it controls the variations in pressure and a diaphragm is used to separate it from the sealed system. 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.

Central Heating systems are a great way to keep your home warm, also they don’t cost you as much as the other systems would. Their ease of operation and versatility is much better than other types of heating.

What must I do to cover against a central heating system breakdown

The boiler in your home is generally ignored in the summertime when warmth is plentiful, but if it does suddenly stop working, you may be stuck with measly kettle fulls of hot water and chilly cold showers everyday. It is only when the gas boiler breaks down that you become acutely aware of its importance in your home. And then you realise how important, not to mention expensive, it really is.

Generally a tenant paying rent is not liable to repair a malfunctioning central heating boiler as the landlord is responsible for maintenance and repair of his premises. Should anything go wrong when you are the homeowner the situation is different so you might think of putting a little aside to cover this risk.

You might consider investing in a new heating boiler model if your previous one is older than ten years, it would cut the cost of your fuel especially if the new one is a high-efficiency model and it would be less prone to breakdown. Your choice of a gas boiler should be determined by the capacity required (based on family needs), the space available for the heating boiler and the existing heating system. For smaller homes with fewer people a combi gas boiler tends to be the most common choice, especially if you want instant hot water at mains pressure. A combi boiler warms up the water as it flows through, removing the need to store the water in a hot water tank. With such a combi central heating boiler, a hot shower is instantly available; however if another hot outlet is opened, your share of warm water will quickly run out and you shower could be a cold one.

A sealed system heating boiler uses a single storage tank, usually in an airing cupboard, and enables a large family to have several taps or showers on the go at once, without compromising hot water or water pressure. The benefit of using a system boiler is that it can be installed quickly and easily in a relatively small area. Compared to a combi boiler, a storage boiler heats water slowly; after depletion, a fresh tankful can take some time to be replenished.

Many older houses have an open vent heating boiler installed, and it is the bulkiest of all; two tanks in the attic and a storage cylinder in the ventilated closet. This has similar advantages and disadvantages to the sealed systems as it enables several taps to be used at once, but you will have to wait for the water to heat and pressure is sometimes an issue.

Lastly, one central heating system type that lets many outlets to be used at once without losing any pressure is the back gas boiler, however it can take up a lot of room. Back boilers are normally placed in a chimney breast, but they are not the recommended type for your house unless your home already has one. It would save you a lot of money on installation of a new central heating boiler if a back gas boiler is already installed in your home when you moved in, as it is cheaper to replace an old back boiler rather than install a completely new heating system.

It is costly to repair a central heating system which ever type your home has. Taking out central heating insurance can provide peace of mind that if something goes wrong with your heating system, your costs will be covered. Buy an insurance plan that includes an annual maintenance contract and emergency house calls and repairs when needed; you will save some extra money and mean you never have to shiver in your shower again.
