The rewards and disadvantages of the different central heating gas boiler configurations
There are a number of sorts of Gas Central Heating Systems on the market these days. Despite the different names basically these systems usually have copper pipework, heating radiators and a gas boiler.
In most parts of the United Kingdom air conditioning is hardly required because of the average temperatures of those regions. 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 Central Heating System.
With the onset of winter, heating becomes crucial to warming your home. A well heated house can help create a comfortable space for you to enjoy with your family. Your Central Heating System needs to be reliable. It is essential to have peace of mind that your Gas Central Heating System is not only practical to use but also safe.
Vented (or pumped) and Sealed heating systems are the two most common types available.
Pumped/vented systems are the most frequent. An expansion tank is present in a pumped heating system. The hot water tank performs two functions; firstly, supply hot water to your house, and secondly, provides heat to the central heating radiators. Any water expansion that may occur due to heating is handled by the expansion tank. A pumped/vented heating system requires that the tank be installed at the highest level within the house – such as an attic or attic space, certainly on the top floor. It performs dual functions by providing hot water and heating up the house.
A lot of older homes have pumped/vented Central Heating systems.
A 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. As the name indicates, a sealed system is a an enclosed system therefore no expansion water tanks are needed. There are no tanks or pipework in the attic, the whole system is sealed, its unvented, which has its benefits:.
- No risk of freezing pipes in the loft.
- No maintenance or repair work is required for the pipes and tank which would have been in the loft.
- Because the system is not vented, there is less chance of water leaking out.
- Unlike pumped/vented systems, air is not drawn through open vents so the possibility of air locks, corroding and sludge is much lower.
- If necessary, the system can be flushed out under pressure using the main water supply.
Such a Sealed Gas Central Heating System is installed with all the required gauges, controls and safeguards. The sealed system gets its water through the main water supply at pressure. It is plumbed straight into the main water 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. The safety valve opens up when the pressure in the system rises so that water can escape through it, on the other hand it opens up when the pressure drops down so that the water can refill the system.
Compared to any other form of heating, Gas Central Heating systems are by far the most practical and economical. They also provide you with complete control which is much more than other heating systems can say about themselves.
