Gas Heating System Alternatives
Purchasing a new central heating system is not a straightforward topic, you first should know what type of system is best suited to your dwelling. Below you will find an outline of the main forms of central heating system currently traded. When you purchase a central heating system you are essentially purchasing a collection of different constituents including a boiler and radiators.
In north Europe the primary household system will be the heating system, although there is much talk of global warming at the moment there is little mass demand for air conditioning systems. The bulk of new houses that are being built in this day and age are built with a Central Heating System.
Whilst we tend to forget about the central heating system it will be operational day-to-day to provide hot water and comes to the fore in the winter when heating your family. You can relax at dwelling house when the heating is functioning. Another important role for the central heating system is to create hot water. Your Central Heating System needs to be dependable. You will want an efficient system that functions in the background without any niggling failures.
Whilst there are several forms the two primary forms of system are vented and sealed systems.
The most common type of system is the pumped/vented system. You will note that this configuration contains a feed and expansion tank in addition to a hot water cylinder. Hot water expands and in this type of system flows back to the expansion tank. If you look for the expansion tank in an existing system you will most commonly find it in the attic.
As thinking develops sealed systems are now more normally being installed in homes. Sealed systems have less component parts having no need for the water expansion tank. The role of the water feed tank is now provided by the cold water mains. There are no tanks or piping in the loft, the whole system is sealed, its unvented, which has its benefits:
- as the pipe work is removed from the attic it will not be in danger of freezing in the winter
- fewer elements mean reduced purchase costs
- less copper piping and joints to leak
- as the system is sealed there is less chance of air entering leading to corroding or air locks
Normal variances of pressure can be permitted in a sealed system through a pressure vessel that holds compressed gas. A safety valve will open if the pressure is higher than advocated. Similarly cold water is allowed into the system if the pressure is lower than the advocated level.
