The leading variants of central heating systems
Before you purchase a central heating system you need to picture what type of system and boiler you will require. Below you will find an outline of the main types of central heating system presently traded. When you purchase a central heating system you are essentially purchasing a collection of different parts including a boiler and radiators.
In terms of the systems within your family the central heating system will be one of the most costly and the one that is in daily use, and cooling systems are seen less frequently. Most existing houses and virtually all new home developments now incorporate central heating systems to heat the household and supply hot water.
Having become used to modern amenities we cannot do without a heating system. You can unwind at dwelling house when the heating is working. In addition to heating the home the central heating system will be used to supply hot water when required. Dependability is a major requirement for your central heating system. You want to match the central heating system to your home requirements so that it both meets your needs and uses gas efficiently.
There are two primary types of Central Heating System; pumped/vented and sealed systems.
The most common type of system is the pumped/vented system. A pumped or vented Central Heating System has a hot water cylinder and a feed and expansion tank. 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 tank is placed in the highest place in the home, normally the loft area.
If you purchase a new household you may now find that it incorporates a sealed central heating system. A sealed system, as the name suggests is a closed system so no water tanks are needed. The mains water is used to supply the sealed Central Heating System. This frees your loft of the expansion tank and pipework, you get a range of advantages from the elimination of these elements:
- frozen wintertime pipe work from copper pipes in the loft it is now eradicated
- there are fewer system components reducing any maintenance requirements
- less chance of leakages
- you will get fewer problems from air ingress leading to corrosion or blocks
Typical variances of pressure can be allowed in a sealed system through a pressure vessel that contains compressed gas. This system has a valve that allows mains water to enter the system if the water pressure has dropped down. An alternative valve will open if the pressure is detected as being too high.
