Before you buy a central heating system you need to establish what type of system and heating boiler you will want. Below you will find an outline of the main variants of central heating system presently traded. Most if not all of these Central Heating System comprise of a heating boiler, radiator and copper piping.
Whether you are buying a new development or established family you will find that it will contain a central heating system which is a modern day essential. Virtually all new housing developments incorporate central heating systems as a common fixture within the household.
Try running a household without your central heating system switched on and you’ll quickly visualise how important the system is. A new central heating system can give your family the atmosphere you are looking for. A central heating system also delivers hot water for bathing and washing. Your Central Heating System needs to be reliable. You want to match the central heating system to your family requirements so that it both meets your requirements and uses gas efficiently.
You will find two main system variants, vented and sealed central heating systems.
pumped/vented systems are the most common. A feed and expansion tank is incorporated into this form of central heating system alongside a hot water cylinder. Water expands when warmed and the expansion tank allows for this. The attic is most commonly used to house the expansion tank as it needs to be high in the house.
If you purchase a new home you may now find that it contains a sealed central heating system. The water expansion tank can be dispensed with in a sealed central heating system. The water for a sealed Central Heating System is rendered direct from the main water supply. It feeds directly from the primary water supply. This eliminates the requirement for any pipework or central heating water tanks in the loft, you get a range of advantages from the elimination of these elements:
- you don’t need to worry about pipework in the attic freezing
- there are fewer system constituents reducing any maintenance requirements
- fewer leaks from pipework joints
- the sealing of the system precludes air entering which could lead to interior corrosion or the evolution of an air lock
It is familiar for the water supply pressure to vary and that this is dealt with by integrating a pressure vessel. If the pressure becomes too high in a sealed Central Heating System; a safety valve will allow water to escape from the system and if the pressure drops too low a valve will open to replenish the system with water.
