The benefits and drawbacks of the variant heating gas boiler models
Central Heating systems come in different forms. These systems for the most part are made up of a number of central heating radiators, pipework and of course a gas gas boiler.
In most parts of the UK air conditioning is hardly needed because of the average temperatures of those regions. In fact, a decent central heating system is a necessity in these regions, and due to this, a majority of new houses have a Central Heating system.
A reliable Central Heating system is important to keep your home warm especially during winter months. Heating your home provides a relaxing and cosy atmosphere. Therefore your heating system needs to be efficient and reliable. It is essential to have peace of mind that your Central Heating System is not only practical to use but also safe.
Pumped/vented and sealed are the two main types of Gas Central Heating Systems on the market.
The most commonly used systems are pumped/vented Gas Central Heating systems. The basic differentiating components of such a system are a feed and expansion tank. The hot water storage tank provides your home with warm water and brings heat to the radiators. The expansion tank has adequate space to accommodate any water expansion that occurs due to heat. The tank is positioned at the point of maximum height, usually in the attic area to create water pressure. The tank provides a dual supply of hot water and warmth for the house.
A pumped/vented 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 Gas Central Heating system is the sealed system. As the name suggests, sealed system is a closed system; no tank is required in this system. This unvented system eliminates water tanks and loft plumbing, thus giving a number of advantages.
- The problem of freezing pipes is eliminated.
- No maintenance work on the tank or pipes that would be in the attic in a pumped/vented system.
- The risk of leakage is cut as there are fewer pipes and the system is less complex.
- 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.
- If necessary, the system can be flushed out under pressure using the main water supply.
A sealed Central Heating System is a system with the required controls and safety equipment all contained in one. No tank feeds a sealed system, the supply comes directly from the mains. The main water supply feeds the system immediately under pressure.
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.
As compared to other heating systems, Gas Central Heating systems are cheaper to run. They also provide you with complete control which is much more than other heating systems can say about themselves.
