Is your gas heating system vented or sealed
Before you get a central heating system you need to interpret what form of system and gas boiler you will require. Below you will find an outline of the main variants of central heating system presently sold. Most if not all of these Central Heating System comprise of a central heating boiler, radiator and copper piping.
Whether you are purchasing a new development or established family you will find that it will contain a central heating system which is a modern day necessity. The bulk of new houses that are being built in this day and age are built with a Central Heating System.
Heating is vital, particularly in winter. No one would deny how a household is changed when we install an efficient heating system. A central heating system also provides hot water for bathing and washing. For these reasons your central heating system has to be dependable. You will want an efficient system that runs in the background without any niggling breakdowns.
There are two primary variants of Central Heating System; pumped or vented and sealed systems.
Expect to find a pumped or vented central heating system as they are the most usual. You will find that this configuration contains a feed and expansion tank in addition to a hot water cylinder. In addition to allowing for water expansion when heated the expansion tank also tops up the central heating system with water when called for. The expansion tank needs to be mounted higher than the other system constituents and most often this will be positioned in your attic.
If you purchase a new family you may now find that it incorporates a sealed central heating system. Sealed systems have fewer constituents having no need for the water expansion tank. The mains water is used to supply the sealed Central Heating System. This eliminates the requirement for any copper piping or central heating water tanks in the attic, you get a range of benefits from the elimination of these elements:
- as the piping is removed from the loft it will not be in danger of freezing in the wintertime
- there are fewer system elements reducing any upkeep requirements
- fewer leaks from pipework seals
- sealed systems do not have airlocks and the absence of air cuts the likelihood of interior corroding
Any water pressure variations are accommodated by the incorporation of a pressure vessel. If the pressure becomes too high in a sealed Central Heating System; a escape valve will permit water to escape from the system and if the pressure drops too low a valve will open to refill the system with water.
