The most usual type is a pumped or vented system. A feed and expansion tank is incorporated into this form of central heating system alongside a hot water cylinder. Hot water expands and in this type of system courses 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.
If you purchase a new household you may now find that it incorporates a sealed central heating system. The water expansion tank can be dispensed with in a sealed central heating system. A sealed Central Heating System is attached to the mains water supply to allow the removal of the water feed tank. if you embrace this system you don’t need to use your attic for housing in the expansion tank thereby saving space, you will get the following benefits when adopting a sealed system:
- you don’t need to care about piping in the loft freezing
- there are fewer system component parts reducing any upkeep requirements
- less chance of leakages
- you will get fewer problems from air entry leading to corrosion or blockages
It is usual for the water supply pressure to change and that this is dealt with by incorporating a pressure vessel. Valves allow cold water to enter and top up the system when pressure falls, other safety mechanics open valves if the inner pressure is to high.
