Selecting your next Central Heating System
Selecting your next Central Heating System
Purchasing a new central heating system is not a plain subject, you first should understand 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. The main component in a central heating system is the gas boiler and this will be selected in accord with your needs.
Air conditioning systems are not yet a frequent feature in households whereas every northern European family is built with a form of central heating. Virtually all new housing developments incorporate central heating systems as a stock fixture within the dwelling house.
Whilst we tend to forget about the central heating system it will be functioning day-to-day to furnish hot water and comes to the fore in the winter when heating your family. You can relax at dwelling when the heating is operational. In addition to heating the dwelling the central heating system will be used to supply hot water when required. You need heating and hot water every day so you need a system that you can depend upon. Systems tend to last for fifteen years and you will require one that is both efficient and reliable.
The main variants of the central heating system are sealed systems and pumped systems.
The most common type is a pumped/vented system. A pumped or vented Central Heating System has a hot water cylinder and a feed and expansion tank. The expansion tank allows the system to be topped up with water and creates space for the hot water to expand when the heating system is used. The expansion tank is positioned high up in the house often in the loft.
A more modern alternative is a sealed system. There is no need for the water expansion tank if you choose to have a sealed central heating system fitted. 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, the whole system is sealed, its unvented, which has its benefits:
- taking out the copper pipes from the attic removes any risk of them freezing
- fewer components require less maintenance
- less chance of pipework developing leakages
- as the system is sealed there is less chance of air entering leading to corrosion or airlocks
It is frequent 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 mechanisms open valves if the interior pressure is to high.
