How many variant types of central heating boiler are there
Various types of Gas Central Heating Systems are available in the market. These systems for the most part are made up of a number of heating radiators, pipework and of course a gas gas boiler.
People in the UK, Europe and some parts of Russia, hardly need an air conditioner because of the low average temperature. Heating is more in demand particularly in the chilly wintertime, making a Gas Central Heating System an absolute must-have for all modern houses and all those located in the United Kingdom.
As autumn fades and chilly winds begin to blow, householders turn to their Central Heating for warmth and comfort. Only then you can relax and feel cosy inside your house. For this, you need a reliable gas boiler in your Gas Central Heating system. Additionally, your heating system should also be safe, user-friendly and durable.
Pumped/vented and sealed are the two main types of Gas Central Heating Systems on the market.
The vented/pumped one is more common of the two. Heating systems using the pump or vent process are equipped with a tank to allow for feeding of replacement water and expansion of heated water. The hot water storage tank provides your home with warm water and brings heat to the radiators. Water expands when heated; this expansion is accommodated in a feed-expansion tank. It is normally placed at the highest place of the house like the attic area, taking up space. 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 slightly newer central heating boiler is sealed heating system and this is the preferred heating system in newer properties. No water tanks are needed with the sealed system. There are no pipework or tanks also in the attic, the system is sealed in the true sense and it has its own advantages.
- There is no chance of pipes freezing in the attic.
- attic space is freed up and pipe maintenance is reduced.
- Because the system is not vented, there is less chance of water leaking out.
- 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.
- It is possible to flush out the system if required by using the mains 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 feeds directly from the main water supply.
Pressure variation can be regulated by a pressure vessel holding compressed gas; the hot water is pressurized by a diaphragm which also separates the water from the compressed gas. 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.
Central Heating systems are a great way to keep your house warm, also they don’t cost you as much as the other systems would. And they provide you with much more control and choice when it comes to your heating compared to any other systems.
