Houses have contrasting types of central heating system
There are various kinds of Gas Central Heating Systems that can be purchased in the market. Almost all these systems have a central heating boiler at the core, with pipework connecting it to central heating radiators.
In most parts of the United Kingdom air conditioning is hardly required because of the average temperatures of those regions. Today a good Gas Central Heating system has become a major part of every household, so much so that it is being fitted in all the new houses that are being constructed.
Central Heating is vital, especially as winter is fast approaching. A well heated house can help create a comfortable space for you to enjoy with your family. This security in winter is possible only if your Central Heating System is foolproof, well maintained and functioning efficiently. A good central heating system should inspire confidence, give value for money and be simple to operate.
Pumped/vented and sealed are the two main types of Central Heating Systems on the market.
Pumped/vented systems are the most common. An expansion tank is present in a pumped heating system. Your central heating radiators are heated and your water is stored in a hot water tank. The expansion tank has adequate space to accommodate any water expansion that occurs due to heat. It is normally placed at the highest place of the house like the attic area, taking up space. It performs dual functions by providing hot water and heating up the house.
Many homes feature a pumped/vented Central Heating System, particularly the ones constructed several year ago.
A slightly newer boiler is sealed heating system and this is the preferred central heating system in newer properties. 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 loft, the whole system is sealed, its unvented, which has its benefits:.
- Frozen attic pipes are no longer a problem.
- No maintenance work on the tank or pipes that would be in the attic in a pumped/vented system.
- Because the system is not vented, there is less chance of water leaking out.
- As there are no open vents, air cannot enter into the system and so the risk of corroding, airlocks and sludge is drastically cut.
- Can be flushed out under pressure if needed by the mains water supply.
Such a Sealed Central Heating System is installed with all the required gauges, controls and safeguards. The water for the system is provided directly from the main water pipe of the house. It feeds directly from the main water supply.
Normal variations of pressure can be allowed in a sealed system through a pressure vessel that contains compressed gas; this is separated from the sealed system water by a diaphragm. 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.
