The benefits and drawbacks of the diverse central heating boiler types
There are several kinds of Central Heating Systems that can be purchased in the market. 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.
Across the majority of Northern Europe the climate is not warm enough to warrant air conditioning. That is why in the UK most houses built these days are constructed with Central Heating Systems fully integrated into the home.
Heating is vital, especially as wintertime is fast approaching. You can make your home more comfortable, pleasing and relaxing by heating it with Gas Central Heating. Therefore your heating system needs to be efficient and reliable. You should feel that your Central Heating System is safe, easy to use and long lasting.
There are two main types of 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 includes components known as a feed and expansion tank to allow for the expansion of water as it is heated in the radiators. The tank supplies your house with hot water and provides the radiators with heat. The expansion tank has enough space to allow for the expanding of water as a result of heating. The tank is placed in the highest place, normally the loft area. It serves a dual purpose by heating the house and also supplying heated water.
A lot of older homes have pumped/vented Central Heating systems.
A slightly newer, more up-to-date central heating boiler that many people are choosing over a pumped/vented Gas Central Heating system is a sealed system. No water tanks are needed with the sealed system. In the absence of water tanks and pipework, the whole system is sealed and vented; here are some prominent benefits of such a system.
- As there are no pipes, they cannot freeze up in the attic.
- No maintenance or repair work is required for the pipes and tank which would have been in the loft.
- The risk of leaks is decreased.
- 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.
- If necessary, the system can be flushed out under pressure using the main water supply.
A sealed Gas Central Heating System is a packaged unit with all the necessary controls and safety devices. The mains water supplies the water required for the sealed Gas Central Heating system. It is plumbed straight into the main water supply.
Separated from the sealed system by a diaphragm is a pressure vessel, which contains compressed gas; this vessel is responsible for managing variations of pressure in the heating 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 refill the system with water.
Compared to any other form of heating, Central Heating systems are by far the most practical and economical. Moreover, they offer all kinds of control, which are normally not found in other heating systems giving you a more enjoyable environment.
