Sealed and vented are two gas heating system types
Purchasing a new central heating system is not a straightforward subject, you first need to visualise what type of system is best suited to your dwelling house. Below you will find an outline of the main forms of central heating system presently traded. Most if not all of these Central Heating System comprise of a boiler, radiator and pipework.
In terms of the systems within your dwelling house the central heating system will be one of the most expensive and the one that is in everyday use, and cooling systems are seen less frequently. The bulk of new houses that are being built in this day and age are built with a Central Heating System.
Try running a household without your central heating system switched on and you’ll quickly picture how important the system is. No one would deny how a dwelling is transformed when we install an economic heating system. Hot water production is another important role in the life of a central heating system. You need heating and hot water every day so you need a system that you can depend upon. You should find that your Central Heating System is safe, easy to use and long lasting.
Whilst there are many varieties the two primary forms of system are vented and sealed systems.
The most usual type of system is the pumped/vented system. The main difference you’ll see is that this form of heating system in addition to the hot water cylinder is that it has an expansion tank. Hot water expands and in this type of system runs back to the expansion tank. If you look for the expansion tank in an existing system you will most normally find it in the attic.
A slightly newer, more present-day system that several people are choosing over a pumped/vented central heating system is a sealed system. Sealed systems have less elements having no need for the water expansion tank. A sealed Central Heating System is connected to the mains water supply to allow the removal of the water feed tank. if you take this system you don’t need to use your loft for housing in the expansion tank thereby saving space, you will get the following benefits when adopting a sealed system:
- no chance of freezing pipes in the attic
- fewer parts require less upkeep
- fewer leakages from copper piping seals
- you will get fewer problems from air entering leading to corroding or blocks
A sealed system accommodates variations in pressure in the water supply by using a water pressure vessel. A safety valve will open if the pressure is higher than recommended. Similarly cold water is allowed into the system if the pressure is lower than the advocated level.
