Sealed and vented are two gas heating system variances
Central heating systems have improved and that there are now several different variants each with differing advantages and drawbacks according to your needs. In this page we will discuss that the variants of central heating system available to help you fit them to your requirements. The main component in a central heating system is the gas boiler and this will be chosen in accord with your needs.
Whether you are purchasing a new development or established household you’ll find that it will contain a central heating system which is a modern day essential. Whether you are looking at a completely new dwelling house or an established house one of the characteristics you will need to investigate is its central heating system.
Try running a home without your central heating system switched on and you will quickly visualise how important the system is. No one would deny how a household is transformed when we install an economic heating system. In addition to warming the household the central heating system will be used to furnish hot water when called for. Your Central Heating System needs to be reliable. Systems tend to last for fifteen years and you will require one that is both efficient and dependable.
Pumped systems and sealed central heating systems are the two main forms.
Expect to find a pumped/vented central heating system as they are the most usual. This type of system has a feed and expansion tank in concert with a hot water cylinder. Water expands when heated and the expansion tank allows for this. If you look for the expansion tank in an existing system you will most commonly find it in the attic.
A slightly newer, more up-to-date system that numerous people are choosing over a pumped/vented central heating system is a sealed system. Sealed systems have less component parts having no need for the water expansion tank. The mains water is used to supply the sealed Central Heating System. There are no tanks or pipe work in the attic, the sealed nature of the system without any venting delivers a number of benefits:
- you don’t need to worry about pipe work in the attic freezing
- there are fewer system parts reducing any maintenance requirements
- reduces the risk of leaking
- sealed systems do not have airlocks and the absence of air cuts the likelihood of interior corrosion
Typical variations of pressure can be allowed in a sealed system through a pressure vessel that contains compressed gas. Safety valves open if the interior pressure is too high. Other automated valves open to allow the interior water to be topped up if it drops to low.
